When you open a document, the corresponding history is generated. For example, opening a Word document will generate a shortcut in [Document] (under XP, my recent document) and leave traces in the list of recently used files in word[. This way, every time you have to clear the document record, very troublesome. The following simple method allows you to hide a variety of document browsing records with the help of WinRAR. Set up a RAR compression package, put the file in. Open the file again and you'll find the trail is all gone! Of course, if necessary, you can also add a password to the files in RAR.
