The "Select extents" choices on the Drives page apply only to the drive that is currently selected from the Drives combobox listing at the top of the page.
Here are the choices provided:
- Clean and delete TMP & TEMP - will find any TMP or TEMP directories on the current drive only and securely delete their contents according to your method selection.
- Clean and delete "/DELETE" - will find any /DELETE directories on the root of current drive only and securely delete it's contents according to your method selection.
- Clean and delete all FreeSpace - will find all FreeSpace remaining on the current drive only and securely delete it so no information can be recovered from it. This effectively overwrites all previously deleted files. Depending on the size of the FreeSpace available and the method chosen, this can be a lengthy process.
- Clean and delete this drive (complete) - will overwrite and delete everything on the current drive only and securely delete it so no information can be recovered from it. This effectively overwrites all previously deleted files as well as existing files. Depending on the size of the drive and the method chosen, this can be a lengthy process.
