As the title suggest, if you select a folder (or directly the files in it) with a lot of files and you drag and drop it into the app GUI, Permadelete doesn't work and doesn't exec shred operation. In an another case, you must to shred the same folder multiple times in order to get the files in it shredded correctly.
