Permission Issue - On download - No error being thrown

Version: 4.3.2 (Build 1201)
OS: Windows 7, Windows 2008 R2
Usage: Command line and scripting
Type: SFTP sites

I only have read only and execute permissions to winscp installed directory. I can connect to site and download file. 'lls' command shows file successfully downloaded but the file does not really exist on file system.

I've exited out and started winscp again. The 'lls' command still shows that the file is still there.

I often use get with -delete option. Winscp believes that it downloaded the file and goes ahead and deletes the file on remote server but the file was never actually stored on the filesystem.

This stared when my account was removed from the Admin group on the machine. Everything works correctly when I run from a directory that I have Read, Execute, and Modify permissions.

Thanks


Example: Files test2.txt and test3.txt where downloaded from our local SFTP site. They are empty files created with Notepad. I have tried files of varying size as well.

This show the actual directory listing and what winscp is reporting.

It's likely due to file system redirection functionality of Windows 7. It allows WinSCP to "write" to directory you do not have permissions to by actually writing them elsewhere. Application aware of the redirection functionality won't show such files.
