Yes, Tools>Drive Wiper>Wipe free space.

It is meant for use if you are selling/passing on your computer or hard drive, so that the new owner can't recover your deleted files.

That will overwrite all the free space on your disc (where the deleted files used to be) with random data (Xs & 0s or similar) and then remove that random data  again, so there is no chance of a recovery programme getting them back.

One pass is enough, any more is unnecessary overkill - but the option for more passes is there if you are feeling especially paranoid.

It will overwrite all the free space on the disc and so will take time to do that, especially on larger drives.
You should let it complete, if it stopped for any reason then your disc will be left full of random data which you will then have to delete manually. (We've seen that happen with a power failure or laptop battery running out).

 

If i do this, does all my data got wipe out?. because i still use my pc and i only want to delete those permanently deleted data
