I just found that I have 4 GB of space in
/Documents and Settings/<user name>/Local Settings/temp.Is there any reason why I shouldn’t go and delete these?
Solution:
The location you mentioned is the default location for System Environment Variable “TEMP” or “TMP”.Applications use the TEMP for storing temporary data, data that will be needed for the specific user session & installers use it to extract the data from the compressed installation files.You can safely delete any files that are not locked. (Locked files are still being used by application for storing user data).The easiest way will be using CCleaner a freeware to do it for you.
