Before getting into that discussion let’s talk about what happens when you click on a file and hit the Delete key. The file goes to Recycle Bin. Then you go to Recycle Bin and empty it. Now it seems that the file has disappeared for good. Unfortunately, that’s not the case. 1’s and 0’s of the file still remain and with the right software, the entire file can be recovered. So, how to make sure the file is deleted? There are several ways.
The simplest way to delete a file for good is to overwrite the area in the hard drive with other data. This is accomplished by a Free software called Eraser. The software erases a file from the hard drive by overwriting it several times with carefully selected patterns. It is very easy to use and is very effective.

Other options include: sDelete and Mac’s Disk Utility (for Apple users).

In conclusion, it is always a good idea to delete sensitive files for good. Moreover, wiping out the hard drive before throwing the computer away or gifting it to someone is also recommended. Otherwise, sensitive personal information can be recovered and used for unwanted benefits. The last option for getting rid of the data permenantly is to just hammer down the hard drive and trashing it.
