My Question is I want to erase a file in OS X Securely (like the function of "Secure Empty Trash") so that, the file cannot be recovered by using recovery tools. I don't want to empty the trash. It is possible to erase Files Securely in OS X without moving the file to Trash ?
You can always use the terminal command
rm with the
[Option -P will] Overwrite regular files before deleting them. Files are overwritten three times, first with the byte pattern 0xff, then 0x00, and then 0xff again, before they are deleted.
If you're not handy with the Terminal, just:
- Open the Terminal.app (Found in /Applications/Utilities).
cdand drag the folder which contains the file you want to delete, to the terminal window.
rm -P FileName.extensionand hit Enter
srm is another shell utility for deleting files securely. It uses the 35-pass Gutmann algorithm by default, but
-s (overwriting files with random data once) is faster and should be secure enough for most purposes.
