Clean out unneeded files on your hard drive

There are two types of files you can delete to help clean up your hard drive: your old, unnecessary data files and stored temporary files. Temporary files come from Web browsing or are created when applications have problems and don’t close properly.

Many people keep too many files because they are afraid to delete the wrong file or are afraid they will delete something that they may need to look at the next week or next month. But, did you know that when you delete files, they go into the Recycle Bin and stay there until you delete files from the Recycle Bin? This allows you to recover a “deleted” file by restoring it back to its original location.

NOTE: The Recycle Bin does NOT keep a copy of any file or folder deleted from other locations (network drive, flash drive, or other).

Delete your old, unnecessary data files. Deleting these files will make it easier to find the files you want to work with. Also, you need a lot of free space (minimum of several GB) on your hard drive for temporary files created by Windows and your applications while they are running.

When you delete files from the Recycle Bin you will most likely want to delete the oldest files, for example files that were deleted more than three months ago.

  1. Double-click on the Recycle Bin icon on your desktop.
  2. Click on the “Date Deleted” column heading as it is an active button. The files and folders will now be listed in chronological order.
  3. Select the files (and folders) to be deleted.
    • To select consecutive files or folders, click on the first item, press and hold down the Shift key, and then click the last item.
    • To select files or folders that are not consecutive, click on the first item, press and hold down the Ctrl key, and then click each additional item.
  4. Press the Delete key or right-click on any selected file or folder and choose Delete from the Shortcut menu.
  5. Click Yes in the Confirm File Delete dialog box.
