File filter does not work in MSIE Cache directory

Hi, in DOpus I have a folder like this:

C:\Users\Peter\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low\Content.IE5\W20R6LVJ

In this directory there are different file types: JPG, GIF, MP3, HTM, JS, PNG, etc. etc.

When I am in this directory and apply a file filter such as e.g. *.GIF it does not work! (While it does work in other directories).

Why the file filter does not work in this directory and how can I make it work?

OS: W7 x64 SP1

Best wishes to all for the new year!

You're might be viewing the cache as a virtual folder (with the view supplied by Windows and not supporting Opus's filters). If so add it to the list of folders to treat as real under Preferences / Folders / Virtual Folders.

If it's not that, have you checked that there actually are .GIF files below that path?
