Depending on the cause, you can take several approaches to solving this problem. You can add more hard drive space by replacing your drive with a larger one or you can add an additional (internal or external) drive. But try the simple solution first: Close any open files or programs that you don’t need and restart your computer to release the page file. If you are running antivirus software, try disabling the program temporarily. If that solves the problem, you should contact the antivirus software’s publisher to see if there is an update or a workaround.
You should also consider deleting files or programs that you don’t need by running Disk Cleanup. To do so, click Start and select Programs, Accessories, System Tools, and Disk Cleanup. You’ll see a dialog box labeled Select Drive that lets you select the drive you want to clean up (usually C:/). Select the drive and click OK. When you see the next Disk Cleanup tab, click to select the files that you want to remove and click OK. This will remove the files from your drive and free up space for your other files.
Finally, another option is to run a file compression utility to free up some space on your hard drive.
Note that, in the case of the “file permission” error cited above, your problem may in fact be that you’re attempting to write to a file without permission to do so. This can occur, for example, in a network situation when you have permission to open and look at a file but not to delete it or change its contents. In a case like that, you’ll need to contact the network administrator.
