Noooooooooooooo!!!!!!!!!!!!!!!!

Seems like I just lost about 150 important mails. I copied them from the server, then deleted them from the server. When I tried to open them, it turned out that the files were all empty (0 bytes).

The file format was typical mail format, like:
1336353331.M511406P22629.server1.mymail.org,S=3096,W=3175:2,ad
1338131864.H554013P14219.server.mymail.com,S=2907:2,STcd

After copying, the file names are all truncated, like this:
1336353331.M511406P22629.server1.mymail.org,S=3096,W=3175
1338131864.H554013P14219.server.mymail.com,S=2907

So it seems like WinSCP got cofused with those file names, but there was no error message whatsoever. ;(

Sorry for that. What protocol are you using? Are you able to reproduce the problem with truncating file names? Can you post a session log file showing that?

Hi Martin,

The protocol is SFTP. Find the log below - hope this helps!

The result is a 0-byte file with the name of:
1338397343.H963419P27875.server.xxx.com,S=22838

First, Windows does not allow colon in file name.
Anyway, WinSCP should translate the colon, not trim everything afterwards.
Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

WinSCP (or rather Windows) would behave this way, if you had disabled replacing of special characters on download (it's enabled by default):
https://winscp.net/eng/docs/ui_transfer_custom

Well, it doesn't really matter to me if WinSCP translates the colon or not - the only problem is that the file ends up empty. It seems like there is some inconsistency - one part of WinSCP trims the name, whereas the part that copies the file contents doesn't know the new name?

Yes, replacing of special characters is disabled in my preferences. I did that half a year ago, because enabling it also caused issues - but it believe those were fixed in 5.0.5 - so now I enabled it again. Thanks for the heads up!

I'm afraid there is no email in your profile. ;)

You have to login to see it, as mentioned above.
