Hello,

I'm stumped - I've searched the forums, looked at commands, and can't explain this behavior.

The process is simple: Windows scheduler calls a batch file that makes the Winscp script then calls winscp with it. In the script, we change to a directory, get those files, delete those files, exit.

Where the fault comes in is with the cd command. It seems to refuse to change to the named directory. I've tried it with and without paths.
From my reading, perhaps I need to disable the directory caching - but we're not using a stored session, so I don't see how I can do that via command line.

Batch file:
Code:
rem ftp grab process
  echo *** %date% %time% Starting Pull >> log\winscp-gd.log
  echo option batch abort > log\winscp-gd.winscp
  echo option confirm off >> log\winscp-gd.winscp
  echo option transfer binary >> log\winscp-gd.winscp
  echo open ftp://user@site.com:password@site.com >> log\winscp-gd.winscp
  echo pwd >> log\winscp-gd.winscp
  echo cd /bww >> log\winscp-gd.winscp
  echo pwd >> log\winscp-gd.winscp
  echo get *.csv -delete >> log\winscp-gd.winscp
  echo exit >> log\winscp-gd.winscp
  c:\Progra~1\WinSCP\winscp.com /script="log\winscp-gd.winscp" /log=log\winscp-gd.log > log\winscp-gd.out

* I've looked in the registry (per the docs) to see if there was a setting there for caching directories - didn't see it.
* This started happening with a 4* version of WinSCP, and the update to current version didn't change it.
* This used to work just fine. Worked for over a year. The behavior started about 2 weeks ago.
* I tried to access the tracker link for WinSCP to see if it was a known bug, but I got an error message (I'm probably not allowed in there)

Here's the oddest twist: If I run this directly (logged in as Admin), it works. When called from the Scheduler (as Admin), it fails. I don't see how that should make a difference, but I'll share it in the interest of full disclosure. Should what user the script is called as matter? Ultimately, it needs to work from Scheduler, and I'm willing to change settings/scripts to make that happen.

Thanks in advance!

It seems that the cache is corrupted. Remove HKEY_CURRENT_USER\Software\Martin Prikryl\WinSCP 2\Configuration\CDCache from LIL\fsadmin registry hive.

Thank you for the response.

I had deleted the key previously here (http://winscp.net/forum/viewtopic.php?t=5427) without luck. Just in case I did it wrong, I had another administrator monitor my change this time, and the result was still the same:

Code:
> 2013-10-21 13:45:00.752 Script: pwd
< 2013-10-21 13:45:00.752 Script: /
> 2013-10-21 13:45:00.752 Script: cd /bww
. 2013-10-21 13:45:00.753 Cached directory change via "/bww" to "/".
. 2013-10-21 13:45:00.753 Getting current directory name.
< 2013-10-21 13:45:00.753 Script: /
> 2013-10-21 13:45:00.753 Script: pwd
< 2013-10-21 13:45:00.753 Script: /


Any other ideas? Even some crazy work-arounds? We just need it to work.

Obviously, the cache is not empty. Are you sure you have deleted the registry key under the correct account?

You can also try to isolate your script run from any configuration (including any cache) by using /ini=nul command-line switch. What is a recommended practice anyway:

Did I do it right? That's why I had a second admin screen share with me when I did it the second time. We searched the entire hive for 'CDCache' and removed every instance of it, just in case.

I'll try the command line switch. I don't remember that being an option when I first wrote it!

I have sent you an email with a debug version of WinSCP to address you have used to register on this forum.
