TurboSFV v7.40 - Checksums for reparse points
Notes to TurboSFV v7.40:

TurboSFV now calculates a hash value for reparse points. Independent from the reparse point type, TurboSFV takes the data which is associated with a reparse point and computes a checksum. This works for reparse points which are used with files, but also for those which are used with folders. In other words, a reparse point will be treated like a file, not depending on its content. Thus, a hash value can be created and later on validated.

The Explorer in Windows usually displays 0 Bytes as the size for a reparse point. The size returned by TurboSFV is the size of the associated reparse data, which can't be 0 for a valid reparse point. According to the documentation, the size is limited to 16K Bytes (not confirmed).

For reading the associated reparse point data, only normal user privileges are needed. An application, which tries to create or modify a reparse point, needs administration privileges on recent OS. For a few reparse point types, the data structure is known and can be checked. For other types, the structure is defined by the application and can in principle hold any kind of data.
