I would like to know how to make all the files in my PC that have a certain same extension (*.ii) automatically invisible with DO. I work with IconWorkshop and it creates a cache file for each of my icons. It's quite annoying to open a folder and see all those cache files everywhere. I'm sure DO can hide them, but I have no idea how to do it. Please help.
If you always want it to be this way then you'd probably do well to take a look at Nudel's HOW TO: Understand and Configure Folder Formats FAQ. Once you're familiar with using Folder Formats, you'll want to look at the 'Filters' tab in Folder Formats and add *.ii to the 'Hide Filter'...
Otherwise, you can add the new File Filter Field to a toolbar somewhere for 'on the fly filtering'. You can read more about that in the Opus 82 Changes.pdf located in the programs installation folder.
