The DOS attrib command can clear the O attribute: > [@I have a folder in which Find doesn't work](https://resource.dopus.com/t/i-have-a-folder-in-which-find-doesnt-work/40920/2): > > It's because all the files in that archive have several random attributes set which makes Opus think they're offline files (and by design Opus doesn't try to search offline files). The easiest way to fix it I think is to open a DOS prompt in the roo… If you have a lot of directories to do, you could set up a button to run that command and it should fix them. --- _[View the full topic](https://resource.dopus.com/t/no-thumbnails-with-specific-archives-extracted-via-7zip/42274)._
