How it works:

• choose a single file or a directory
• single files and directories will be treated as a set of files
• there will be no duplicates in a set
• you can apply a set expression to your sets
• operators are: + (union), & (intersect), - (subtract)
• expression tokens need to be separated by spaces (e.g. "A + B", not "A+B")
• you can use round brackets as well
• if you click the export button the files of your result set will be exportet into "Export" in the application directory

What is it good for?

• eleminate file duplicates
• analyse directories for similarities or differences
