The Unicode character is U+202E: Right-to-Left Override, and it forces programs to display text in reverse order. However, there are other ways people can disguise the file extension.ĭubbed the “Unitrix” exploit by Avast after it was used by the Unitrix malware, this method takes advantage of a special character in Unicode to reverse the order of characters in a file name, hiding the dangerous file extension in the middle of the file name and placing a harmless-looking fake file extension near the end of the file name.

It is not worth keeping selections of films on your hard disk – they certainly take up a lot of space. If there are ISO images of applications or videos which will not be used in the future, you can delete them without doubt. Using this information, you can select the unnecessary elements to be deleted in order to clean up drive “C”. This utility is freeware with an English-language interface.Īfter checking the hard disk, the program will show all files which are located there, giving the exact size of each.
