2020-DEC-20 - v8.62 Logo
File properties dialog (Windows)
In the context menu of the file list in the main program, there is a new menu entry, which allows to open the Windows file properties dialog for a specific file, from within the main program.

Multiple property dialogs can be opened and all will be closed automatically, if you close the main program. This option isn't available in TurboSFV LE.
Short path form
For a file name, a short path form exists: Each component in the path can be described with a maximum of 8 characters and the file name itself has an 8.3 alias. The short path form for a file name will now be displayed in the validation details for a file. The underlying file system must support this short form.

The short path form can be copied together with the validation details to the clipboard or exported to a file. This functionality isn't available in TurboSFV LE.
Shell property sheet page: Hash
On the Shell property sheet page "Hash", the calculation of checksums automatically starts for smaller files. A new configuration value allows to individually define the maximum size for a small file.
Other changes and improvements
  • In TurboSFV, all executables are digitally signed. The underlying certificate was renewed.
  • In the main program, the display of file names and path information was improved in case of overlong paths.
  • Some informational messages added for a better user experience.
2020-AUG-30 - v8.61 Logo
Load a checksum file without starting the validation
It's now possible to open a hash file in TurboSFV without immediately starting the validation. This can be useful for analysis tasks, for which a validation of all files isn't necessarily needed or would take too much time, for example
  • Examine, which files are no longer available.
  • Investigate, which files were added since the creation of the hash file.
  • Inspect the total size of all listed files.
  • Analyze the file list by using filter.
  • Export file lists in various formats.
  • Create a new checksum file based on the loaded one.
The hash file can be loaded via a new menu entry, either in the main program or in the context menu of the file in the Explorer.

The new functionality isn't available in TurboSFV LE.
Shell property sheet page: Hash
Added the functionality, which allows to copy just the selected checksum to the clipboard, without any additional information.
2020-JUN-14 - v8.60 Logo
New encoding type: UTF-8
TurboSFV now supports the encoding UTF-8, which can be used for encoding files, which must be encoded in a Unicode capable manner. Along with the already supported encoding UTF-16 (previously labeled as Unicode), there is now a second type UTF-8, which supports Unicode characters.

UTF-8 encodes Unicode characters in a different way: Depending on which characters are frequently used for file and folder names on a system, the size of a checksum file produced by TurboSFV can differ comparing to UTF-16. For example, if a checksum file was generated for all files on a drive, then there can be a big difference.

The default encoding can be specified in the configuration. In addition, it can be specified which of the Unicode encoding types takes precedence over the other.

For the command-line version, the encoding to be used can be specified by a switch. Note, that the values for this switch have changed: If it was set to Auto=2 in previous versions, then this value now means UTF-8. The automated detection can now be achieved with the new value 9.

Other changes
  • Before a validation job in the GUI version can start or finish, a probably opened child window must be closed.
  • Some minor issues fixed in the configuration dialog.
2020-APR-26 - v8.54 Logo
Validation: Export to hash file
A list of files, which are actually displayed in the validation window, can be exported to a new hash file. This list can be adjusted by setting one of the available filters (for example hide non-existing files) or by adding new files with the "Find New" functionality.

Up to now, all files had to be validated before you could export them to a new hash file. This restriction is gone now: All files can now be exported, whether validated or not. The validation process can be interrupted, then the list of files can be prepared (sorting, filtering, adding new files) and exported.

Other changes
  • Export to hash file: Layout of commentary lines changed.
  • Layout of other reports adjusted.
  • Smaller layout issues in the configuration dialog fixed.
2020-MAR-15 - v8.53 Logo
Validation: New column for file list
The file list, which is displayed during the validation of checksums, has a new column, which indicates the absolute path for each file. Like the others, this column can be sorted.

If you right-click on the column headers of this list, then a popup menu appears now, which allows to hide / show columns.
Other changes
  • Checksum files per folder: Improvements for building the checksum file name, depending on the selected option for naming the file.
  • Error fixed, which could occur in the control element of the file list in the main program.
2020-FEB-02 - v8.52 Logo
Configuration: Import and export
All configuration values, which can be adjusted in the TurboSFV configuration dialog, can now be exported to a file. The configuration file can be later used, to restore the previously saved configuration values.

As with changed configuration values, restored configuration values will become active after leaving the configuration dialog by using the save button.
Other changes
  • Layout changed on some configuration pages.
  • A few minor problems in the configuration dialog fixed.
  • TurboSFV now supports Windows 10 #1909.
2019-DEC-14 - v8.51 Logo
Checksum files per folder
With the creation mode "per folder", one checksum file can be created for each folder in the selected folder tree. The save dialog for this mode now provides options for building the checksum file name:
  • Root folder: The file names are based on the name of the folder, which is the root folder of the selected folder tree.
  • Folder name: Each file name is based on the current folder name.
  • File names: TurboSFV tries to build a file name based on the names of the files in each folder. If it fails, then the manual file name will be used.
  • Manual: The file name is the same for all folders and can be specified in the configuration.
In previous versions, the manual file name was always used.

Export of validation results
The results of a validation can be exported to a file. The new version provides two addtional export types:
  • Summary: Provides a compressed report for the last validation.
  • Advanced: Contains a summary and addionally, a list of all files sorted by their validation status.
Command-line: If the switch /s (show details) was used, then probably not all lines with details did appear on the console screen.
2019-OCT-13 - v8.50 Logo
  • New configuration page "Hash file", which contains all settings for the checksum file.
  • For the encoding of the hash file, there is a new option "Auto", which automatically detects the needed encoding (ANSI or Unicode).
Other changes
  • Infotip: Only check for file availability, if files are on the same drive where the hash file is located.
  • Command-line: If output is redirected to a file, then don't pad out lines with spaces.
  • Improved analysis of checksum files.
  • Other minor changes.
2019-AUG-03 - v8.41 Logo
Error handling
Under certain conditions, the underlying operating system may produce unpredictable errors, which are difficult for an application to handle. Depending on the error, an application can stop the execution or retry with different parameters.

TurboSFV now better reacts to these errors and
  • stops the calculation process, if needed,
  • provides an appropriate error message,
  • keeps the user updated in these situations.
The GUI version as well as the command-line versions were changed accordingly.
Other changes
  • Command-line: Improved handling of break signals, which allow the user to interrupt the process.
  • Shell property sheet pages: Improved display of path information.
  • Other minor changes.
  • Command-line: In some cases, the console window title or the cursor style were not properly restored.
  • Main program: In a special situation, some entries in the popup menu were incorrectly en- or disabled.
  • If the calculation process had to stop, the progress could jump to 100%.
2019-JUN-23 - v8.40 Logo
File operations
TurboSFV creates checksum files or read them for the validation of hash values. Optionally, data can be exported into files. The changes in this version refer to read and write operations for files, especially for large files.
  • Less memory usage.
  • Progress indication.
  • The window doesn't longer freeze while loading or saving large files.
  • The operation can be canceled.
Other changes
  • Automatic detection of the encoding for export files.
  • Functionality "export to clipboard" removed: Instead export directly to files.
  • Command-line versions: Improved output to the console and setting the window title.
  • Command-line versions: Improved behaviour in error situations.
  • Minor changes for open- and save file dialogs.
  • Creation modes "per file / folder": One counter wasn't always correctly computed.
  • If in the main program the function "Find new files" was canceled, then the function was disabled in the menu and couldn't be restarted.
2019-MAR-31 - v8.30 Logo
New hash algorithms: XXH32 and XXH64
  • TurboSFV now includes the xxHash digest algorithm, in particular the 32 bit variant XXH32 and the 64 bit variant XXH64.
  • xxHash is a non-cryptographic algorithm and is mainly designed for speed. It's an alternative for other non-cryptographic hash algorithms, but shouldn't be used in environments with special requirements regarding the security of the hash function.
  • XXH32 operates with 32-bit numbers and is optimized for 32-bit environments. XXH32 produces a 32-bit hash value.
  • XXH64 deals with 64-bit numbers and is thus optimzed for 64-bit platforms (64-bit cpu and operating system). The output length is 64 bit.
  • xxHash checksums are stored in a checksum file with the new extension xxh.
Other changes
  • Menu order for available hash functions changed.
  • Minor technical improvements.
2019-JAN-27 - v8.21 Logo
Advanced filter capabilities for the command-line version
Similar to the GUI version, you can now also limit the number of files, which will be processed, in the command-line version, by using file filters.

With the file attribute filter, you can specify whether to include or exclude files with specific file attributes. The file extension filter allows to include or exclude files with specific file extensions.

You pass a filter as a command-line switch to the program. Both filters can be used alone or together. If both filters are used, then a file must meet the criteria of both filters.

With the file argument, you could already pre-select files by using wildcards. Together with the new filters, the file argument works then as a pre-filter.
Other changes
  • Windows 10: The latest build #1809 is now officially supported.
  • Manual: Chapter "Digital signatures" updated.
2018-DEC-09 - v8.20 Logo
Checksum files per folder
Hash files can now be created folder-wise: Each folder will then get a checksum file, containing checksums for all selected files in a folder.

In previous versions, hash files had to be created manually for each folder. Now this job can be done automated: The new mode accepts a set of files, one or more folders or a folder tree, calculates checksums for the selected files and creates automatically a checksum file in each folder.

The new version now has three creation modes (TurboSFV LE: Only Summary):
  • Summary: One checksum file for all selected files.
  • per Folder (new): One checksum file for each folder.
  • per File (old term: Single hash files): One checksum file for each file.
For all modes, files can be searched recursively. Available filters can be used, to limit the number of files.
Configuration dialogs
For the new creation mode, some configuration options had to be adjusted. As a result, the configuration page "create" had to be re-structured, on other pages some options had to be changed, added or removed.
  • Create: The manual hash file name is now also used for the creation mode "per Folder".
  • Create: Some options are only available for the creation mode "Summary".
  • Create (CE only): Options, which can be used to pre-define the state of some menu entries, do only appear, if TurboSFV was started with administration rights.
  • Validate (CE only): Search options removed - instead the state of the menu entry "Search recursive" can be pre-defined. Appears as well only with administration rights.
  • Shell (User): Replaced option "Hide menu entry single hash files" with "Hide menu entry creation mode". If the creation mode "Summary" is activated, then the menu entries for "creation mode" can be made hidden.
  • Administration (CE only): The new options can be defined system-wide.
Other changes
  • The main menu and the explorer context menu now have a sub menu, which provides options for selectiong the creation mode.
  • Save dialog added for the creation mode "per Folder".
  • Some options changed in the save dialog for the creation mode "per File".
  • Improved detection of invalid file names, if manually specified.
  • Re-newed certificate, which is used to digitally sign all executables.
  • More minor improvements.
2018-OCT-07 - v8.12 Logo
File filter available for more program functions
The file filter (attributes and extensions), which was introduced in v8.10 and v8.11 for the creation of hash files, can now also be applied while searching for new files with the following program functions:
  • Analysis of validation results
  • Shell Extension: Infotip
  • Shell Extension: Property Sheet Content
The filter can be separately switched on/off for each function.
Find new files: Number of folders examined
The number of examined folders during the search for new files is now reported in the following program modules:
  • Shell Extension: Infotip
  • Shell Extension: Property Sheet Content
  • Command-line Validate: Analysis
  • TurboSFV CE: The state of one menu switch in the main program wasn't saved / loaded.
2018-SEP-09 - v8.11 Logo
File attributes filter
A new file attributes filter can be used to limit the number of files, which will be processed for the calculation of hash values and which will be added to the hash file.

One or more file attributes can be selected and you have the option, whether to include or exclude the files, which have one of the selected attributes.

This filter can be used standalone or together with the file extension filter.
  • Some control elements in the configuration dialog didn't resize automatically.
  • In a special situation, the state of the file extension filter options wasn't correctly saved.
2018-AUG-11 - v8.10 Logo
File extension filter
TurboSFV can now limit the number of files, for which checksums will be calculated and added to the checksum file by using a file extension filter. One or more file extensions can be added to the filter list and you have the option, whether to include or exclude the files with an appropriate extension. This can be useful, if you pass a folder to the program, but you only want to calculate checksums for certain file types.
  • Include: Files with the specified extensions will be considered, all other files not.
  • Exclude: All files will be processed, except those with the specified extensions.
The filter can be activated / deactivated in the explorer context menu or in the main menu.
Other changes
  • Option "Single: Exclude hash files" removed. The same behavior can now be achieved by using the file extension filter.
  • Improvements regarding the dpi awareness.
  • Minor issues fixed.
2018-JUN-24 - v8.00 Logo
New edition: TurboSFV LE
Along with the Private Edition (TurboSFV PE) and the Commercial Edition (TurboSFV CE), there is now a Light Edition (TurboSFV LE). TurboSFV LE is designed for users, who just need a reliable tool for calculating file checksums, but don't need analysis tools in case of wrong hash values. Comparing to TurboSFV PE, the Light Edition comes with reduced functionality, but is cheaper in price. Thus the following features aren't available in TurboSFV LE:
  • Analysis capabilities
  • Options for creating single hash files
  • Command-line versions
  • Shell extensions are limited
On page Features you can compare the different versions.
Other changes
  • New configuration page Shell (User), which holds all options for the Shell integration, which can be configured by a normal user.
  • Special command-line versions for the Mobile Edition (ME). TurboSFV ME is included in TurboSFV CE.
  • Windows 10: The latest build #1803 is now officially supported.
  • Display issue after changing the theme.
  • Non-recursive "search and validate" didn't work from the explorer context menu.
  • Issue with setting a search folder in the shell property sheet page "Content".
  • In rare cases, a memory leak could occur in the shell property sheet pages.
