A great number of options enables you to do multiple things: create multiple file types, delete files, copy them using clipboard, move them between folders and partitions on your PC, rename files, print out selected documents, create lists of favorite file locations, compare directories by their properties.
In addition, you can mount disk image files so they can be browsed or burned via the system navigator embedded file burning feature; extract file archives, or create them by compressing desired files using popular archiving formats (ZIP, RAR, 7z, and many more), split large files so they can fit on the media you can obtain, and merge them later on.
