backslash in ftp file names - inconsistency?

[StatusQuo]

When you (maybe accidently) rename a remote FTP-file to ..\filename.txt (using backslash instead of slash), TC renames it as you told it.
Because of the leading dot the file is not displayed any more. cm_FtpHiddenFiles makes TC show the file, but:
only the name part after the backslash is displayed (filename.txt).

- The file list is sorted correctly (alpabetically before files starting with a single dot),
- also cm_RenameOnly works OK, showing the complete name (..\filename.txt)

So the displayed file list seems to be the only place that can not deal with backslashes in file names.
Is this a known limitation?

This is for security reasons: When you copy the file, it's copied without the ..\ at the beginning to avoid that it overwrites system files in a higher directory, e.g. via
..\windows\explorer.exe
or so. The file is shown in the list in the same way as it is copied.

I see, thanks for the info.
