We are all familiar with the Windows Explorer, and i believe that in the daily use many people have found one of its biggest shortage, that is there is not a view method to allows us to see the size of each folder (or the contained file/folder numbers). So that when the disk space becoming insufficient, and you want to know which folder is taking up a lot of space, then it is doubly difficult.

When there are a large number of the file or folder names need to be modify, there must be a lot of people will feel headache. After all, the manual slow changing file name is a inefficient and very annoying thing. This moment if you have a set of appropriate file name modifying software, all of this will be very efficient.
