unix -> windows text transfer dropping embedded Ctrl-M

When transferring a text file which contained an embedded Ctrl-M character not associated with any line terminator from unix to windows with SFTP protocol, the Ctrl-M character gets dropped. This does not occur when doing a text transfer on a similar file from windows to unix. I would have expected that Ctrl-M characters would only be stripped in a text transfer if associated with a line terminator, and then only for a transfer from windows to unix. Is this expected behaviour or is this a bug?

I am using WinSCP 4.0.6 (build 358) which I believe is the latest. I cannot verify if this also happens with FTP protocol as our unix hosts only accept SFTP connections.

This has been fixed already. See tracker entry.

I get a "You do not have permission to access this document." from that page. Can you explain how to set up so ^Ms are not showing up on the unix side? I am on version 4.0.3 Build 345
Thx

I have just re-tested my original case with SFTP protocol using both versions 4.1.6 & 4.1.7, and the Ctrl-M is not being dropped. Which protocol are you using?

CTRL+M char issue, WINSCP 4.3.5

When I transfer any file from windows to my AIX server CTRL+M character is displayed in every editable file when opened with VI editor. ALso such file do not get executed because of presence of this character, why CTRl+M character pops up while transferring the file. Is there any reason for this or its just a BUG.

Is the character present in the source file? Depending on that, do you want WinSCP to transfer file intact (i.e. you believe WinSCP is adding the character [this is unlikely])? Or do you want WinSCP to strip the character when uploading? For that see:

I checked the files on Windows XP with various editors but CTRL+M character is not shown. But after file transfer those CTRL+M character appears when I use VI editor.

Have you tried some binary viewer?
