When you erase a file from your computer, you might think that it has really been erased. However, computer technology does not work that way. Although the files are deleted and you cannot see it, in reality it still exists on the hard drive of your computer.
When a file is deleted, the computer views it as something that is not necessary to display. Hence, you cannot see it. The space used by that file is there for the computer to use when there is need for it. When you download a program or save anything new on your computer, the space is used.
External Hard Drive
The file and its contents are still intact on the hard drive of the computer even after it has been deleted. This data can be recovered by using software designed to recover lost data. These software is often used by people who have accidentally deleted files and want to retrieve. Incidentally, the software is also used by forensic investigators when they are trying to find evidence which people have deleted from their computer.
The reason why computer are built not actually delete files and programs is because it would take too many resources to overwrite a file completely. However, for people who are really worried about others getting access to their private data can opt for a software designed to actually wipe the hard drive completely clean. By using this special software the entire hard drive is overwritten with binary digits and the deleted files and data becomes nearly impossible to retrieve. You can select which drive to wipe clean and it gets done without any problems.
