Weird problem.
If I upload larger files (40+ mb) to our company ftp site, I almost always (80% or better) get a corrupted file. The only way I can check the validity of the file is to download it and then do a binary compare.
I'm pretty sure the errors happen in the upload because the downloaded files are always the 'same' (if I download a file 2-3 times, it will always compare fine with the other downloads).
Typically there are only 4-10 bytes different, almost always near the end of the file (these are all 'zipped files, by the way); thus the reason why larger files fail more often, I suppose.
I have tried WS_FTP, IE-FTP and FlashFXP; all give similar errors.
I use WinZip v10.0 (latest build), and FlashFXP v3.4.0.
I have unloaded my virus scanner (Trend SMB), and all other background programs I can find.
I talked to our host techies, and they (and the winzip people) say it has to be in the file transfer software but I ain't so sure. I'm kinda pointing my finger at our host ISP but I really don't know how to go about 'proving' it.
Anyone have a clue about what's going on?
Thanks.
