Shredder

When you’ve had enough of a specific program, video game, or file, the first instinct is to remove it from your computer. Even if removed from the recycle bin, some files can still be brought back thanks to various specialized applications. On the other hand, programs like Shredder use powerful algorithms to make sure they’re gone once and for all.

Can be used on the go

You don’t even have to install the application on your computer to benefit from what it has to offer. As such, you can carry it around with you on a USB flash drive to completely erase files from other computers as well, especially since registries are not affected. The only thing you need to look after is whether or not the target PC is fitted with .NET Framework.
In order to use the application, you need to run it each time, because it doesn’t integrate itself in the context menu, which is a bit of a disappointment. However, the interface is intuitive enough to let you accommodate in a jiffy. Just be careful how you resize the main window, because you risk covering the option to add files, and dragging them over the main window has no effect.

Use preset algorithms or customize the process

Once files are added, you need to select the algorithm you want to use. A pretty impressive variety of types are at your disposal, such as fast removing, Russian standard, GOST P50739-95, US Standard, DoD 5220.22M (E) and (ECE), Bruce Schneier Algorithm, German Standard VSITR, and Peter Gutmat Method.
Moreover, the application gives you the possibility to fully customize the way the deletion process works. This is done by writing down the number of bytes to write, final value, as well as rewrite value. Note that it can take some time to remove files, especially if they take a lot of disk space.

On an ending note

Bottom line is that simply deleting files from your computer doesn’t mean they can’t be brought back, and if you want to completely remove something from your computer, then applications like Shredder are sure to get the job done. The variety of algorithms you can use is impressive, and there’s also the possibility to fully customize the process.
