Most of us face Lower Disk Space problem many times. Windows notifies us about the lower disk space and we are forced to delete some useless files or to resize the partition to get some free space.I'm posting this tutorial to tell some methods to get as mush FREE space as we can.But use it at your own risk. I'll not be responsible for any kind of damage/problem in your system.
I have been using these tips since many years and never faced any problem.

Following are some ways to get lots of free space:1.) First thing is to use windows built-in "Disk Cleanup" application. You can right-click on a drive in My Computer and select "Properties" now click on "Disk Cleanup" button. Now select all given options, like "Downloaded Program Files", "Temporary Internet Files", "Compress old files", etc. Believe me you can get more than 1GB FREE space after using Disk Cleanup coz once I got approx. 1.5GB more FREE space after running Disk Cleanup.
Alternatively you can run "Disk Cleanup" directly from RUN dialog box by giving "cleanmgr.exe" command.
