On android I have a file manager that lists all compressed archive files on android then another icon that lists all pdf files on android
Is that something that can be done with Directory Opus. As this is a really useful to have if your searching for a compressed archive or pdf file. Time saving thing which is cool,
Yes, that can be done by performing the search and then right-clicking the results list and saving it as a Stored Query.
That creates a special file collection which will re-run the search each time you enter it.
I recommend installing Everything from https://www.voidtools.com (if you don't already use it) as it will make the search almost instant via the Global Everything search mode in Opus.
