Hi. I sync my files with Google Drive. I want to make sure about my files are copied exactly the same. Is FFS hashing files with Cloud API (or something like that) or downloading the file and hashing after that? Thanks.

No, you will want to look into "VerifyCopiedFiles"

Hi. Thanks for answer. If I don't change the "VerifyCopiedFiles", it isn't download files to my computer for hashing, right?

For good reasons, FreeFileSync (FFS) does not use hashes (as discussed in this forum in multiple threads).
Instead, FFS uses a plain bit-by-bit comparison.

Is bit by bit or hashing with SHA-1/SHA-256 etc. more reliable?

Theoretically, files can have an identical checksum and still differ in content.
That is however very, very unlikely, and, as explained in said threads, not the reason why FFS does not use hashes.
