Some have confirmed that the useless files are also saved in the hard disk space, want to delete the first after the Recycle Bin, then go to the Recycle Bin to delete, this is a bit of trouble, and sometimes forget to go to the Recycle Bin clean up, or the same space. For the Win7 64-bit flagship version of the release of the people will first go through the Recycle Bin and then delete, small knitting here has a better way, want to simpler words directly delete it.
After the selection of a file by the combination of key shift+delete, then there is a general deletion of the file when the box is not the same, this option box has a "permanent deletion" of the word, press the confirmation file directly deleted, no longer go to the Recycle Bin clean up.
Method Two: Keyboard mouse combination key
Right-click the file you want to delete and, and then hold the keyboard Shift key, here will be pop-up option box, select "Delete", and then confirm.
Warm tip: Permanent delete refers to the file to be deleted without the Recycle Bin, a direct deletion of a way to delete. Because it is not through the Recycle Bin, so deleted, you can not find the file in the Recycle Bin, the same, can not be restored in the ghost Win7 Recycling station, so use it with caution!
