xCRC

If would be great if FXP would support 32-bit CRC as XCRC. I think the only client that supports it now is Globalscape FTP client. I think that this feature that prevents from files being currpted is great

isn't this what SFV check is doing?

Nope, Sfv is for a finished file (you check it then). This FTP command--http://www.southrivertech.com/support/titanftp/webhelp/xcrc.htm

XCRC does same thing...

SFV also calculate CRC32 sum
it's not in any RFC
i see different servers implement it differently..some require to have " " around file name, some don't, some allow calc of crc32 from artitrary file size, some only on full filesize

It's generally a very bad idea to implement something like this into server.. (esp. if server has large files on it) as crc calculation would consume every last bit of cpu time there is left. Likelihood of files being corrupted during transfer over TCP is near 0%.
