Error copying file? : here is solution

Problem:A hard drive can only hold so much data. If you try to copy 2GB worth of files to a drive that only has 1GB of free space left, you’ll get this error.

Solution:In order to cram those new files onto your hard drive, you’ll have to free up some space. Before you begin uninstalling infrequently used applications, run Disk Cleanup (go to My Computer,right-click on your drive,select Properties from the menu, and then click the Disk Cleanup button) to free you drive of unnecessary temporary files, and compress files that you haven’t accessed in awhile.
You can also try clearing older System Restore points that won’t be used any longer (click on the More Options tab in the Disk Cleanup menu,and click on the Clean Up... button in the System Restore section).You’ll be surprised by the amount of space that you can free by doing these two steps if you’ve never used Windows Disk Cleanup feature before. If that doesn’t free up enough space, though, you can start uninstalling applications that you no longer need. Once you’ve you free up the necessary amount
of space, try copying the files again.

Thank You
