I can't really help you with why this is occurring. It should work if the characters haven't been munged in the Winsock transfer process.

We used FWrite years ago in a backup/recovery routine and had no problems with the fact that the files were binary (EXEs) in nature.

Could the data be getting corrupted in transport? Have you examined each block to determine if it is the same going in and out? If you have control of both ends, you could perform a check sum (Sys(2007)) and pass this in addition to the package. On the receiving end, you could strip off the check sum value, and perform another check sum. If they didn't match, you could attempt to retrieve the information again.

One other thing, instead of FWRITE(), you could use StrtoFile() to handle the same thing.

HTH.
