Option - free useful tips to make some free space on C drive

Here we would like to introduce some free useful tips to make some free space on C drive.

Step 1. Delete all the temp files to free your hard disk drive space. There is probably a lot of junk on C that you could move (or delete) to reclaim a lot more space- temp files (delete), /Windows/$NTUnistall* folders (move or delete anything more than a few months old), *.dmp files (delete), and probably some junk in /temp (probably delete). Be aware that this may add only a little space to your c drive.

Step 2. Place the pagefile to some other drives other than c drive. Right click My Computer—Properties—Advanced—Performace(Settings)—Adanced—Virtual Memorry(Change) then you can allocate the pagefile to some other drives. However it can only make less than 2G space which depends on the current size of the pagefile.

Step 3. Uninstall programs in c drive and install them to another drive.
