Compare local - server: show as different by content but isn't?

[dirk-o]

I have compared local files with files on the server by content. FFS shows them as unequal. I have then downloaded some of those files and checked / compared again with FFS, now it shows them as equal. Why might it be like that?

And how could I get the right result, when I compare local files with the ones on a server?

And FFS shows different file sizes by comparing local-server of those files and same file sizes after downloading them.
