.net – There is in Windows file systems a pre computed hash for each file


I want to search a file duplicate by its hash. For performance purposes I want to know if there is a stored hash/checksum for each file in NTFS/FAT file systems. If there is, I don't have to compute them all to search my file.

If there is, how to access it using .NET?

If it helps, it will be JPEG files. Do they have a checksum?

There is no such thing.
