Free up space on your drive by deleting temporary files. The first step in looking for temporary files is to quit all of the programs you're running. Get out of them all; no exceptions! You never know whether those programs are creating temporary files. If so, you won't be able to delete the files.
Use the Windows Search feature to locate the different files on your system that have the following characteristics and then delete them -- after determining that it's safe to do so:
.tmp extension: By far, the most common indicator of a temporary file is one that ends in the .tmp extension.
Tilde (~) as first character: Not content with conforming to the .tmp extension standard, some programs create temporary files that begin with a tilde. For instance, you may see a file named ~DF3E05.tmp.
Zero file length: Sometimes a program may create temporary files and put nothing in them. Since these files have no characters, they have no size.
.bak extension: Technically, these files are not temporary. Instead, they're backup files. If the file is old, you may not need it anymore, and you can safely delete.
.old extension: When programs update some files, they rename the original file with the .old extension.
