|If you drive is nearly full, simply deleting a few files may not be enough. |
First delete any or all files you do not need.
second empty recycling bin
third go to add-remove programs and uninstall anything you do not use.
fourth check your swap file to see if it is too large - allow windows to manage or manually set to 1 1/2 times RAM
fifth turn off system restore, wait a moment and turn back on again (you may have more restore points than needed taking up vital room)
If this together is not enough, consider getting an external hard drive and moving off many of your files that you do not always need with you.
