This is a simple app but is indispensable for me. As a designer, I'm visual when it comes to organizing my graphic files, fonts, stock photos, etc. The containing folders serve me better by a visual icon rather than text and while I use FolderBrander for client/job names on folders, I use Telling Folders for much of the rest.
- Drag a Font file preview on top of the app and it will show as icon for that font family's folder.
- Pull a logo from a site as the folder icon for files from that company or client.
- Make a marquee screen shot of whatever and use it as folder icon.
- Album folders in my music collection will get the cover art on them.
Lastly, it handles transparency so png's will work and not be stuck with a square border icon.
