I got this info from a friend. Tried it and it works!
good luck.
What's actually happening is that when you "delete" a file, the file is actually MOVED to the Recycle Bin folder.
That's done so you can un-delete a file you deleted by mistake.
If you open the Recycle Bin, select one or more files that are in the bin, and press the Delete key, those files will be permanently deleted.
You can completely EMPTY the recycle bin at any time. Either open it and then choose Empty Recycle Bin from the File menu, or just right click on the Recycle Bin icon and choose Empty Recycle Bin from the pop-up menu that appears.
To delete a file and bypass sending it to the Recycle Bin, you can use either of two methods:
1. Select the file(s) to delete. Hold down the Shift key while pressing the Delete key. A popup window will ask you to confirm the delete.
2. Right click on the selected file(s). Hold down the shift key while click the Delete option from the popup menu that appears. A popup window will ask you to confirm the delete.
Once you OK the delete, the selected files will be completely deleted.
