Thanks for your help. Now I've run into something else.
I had set up an FTP operation in a package some time ago and it was working fine. I tried to run it again today and it failed saying that there were no files available. The execution log showed a successful connection and that it had changed directories as specified, but then 0 files found. Running an FTP session with the FTP supplied with Windows from the same box, using the same login, I can see a long list of files. I am at a loss as to why VImp cannot find the files which are there.
When configuring my FTP action in the package I see that I get success when I try the "Connect" button. I also see that the "Files List:" box has nothing but the root directory listed ("/"). Hovering my mouse cursor over the box I am prompted to "Double click to browse directory", but when I try that it doesn't show any files (other than the root directory) and updates my "Remote Directory:" specification to the root directory.
Can you suggest anything I can do to determine why this isn't working? I did upgrade from 7.2.0 to 7.2.3 a few days ago, but I cannot think of anything else that has changed since I created this FTP action and it was working.
