9 Best Free Open Source File Shredder Software For Windows

Here is a list of best free Open Source File Shredder Software for Windows. These open source file shredder software work exactly like file shredder software listed here > Free File Shredders. The only difference is that these software are open source and you can easily access and manipulate their source code without any restriction.

The main task of file shredders is to delete files in a way that no one can ever recover back the deleted files, even by using file recovery software. These software use many deleting algorithms or methods to delete files like GutmannUS Air Force 5020Filecutter, etc. These methods basically overwrite garbage data over the original data multiple times to make original data unrecoverable. You can select any one of the shredding methods to shred files. In some software, you can also select the number of overwriting iterations. Overwriting iterations mean the number of times a selected shredding method overwrites garbage data over the original data. The number of overwriting iterations directly affect the file shredding time, so carefully select the number of overwriting iterations. Apart from files and data, you can also shred empty disk space and disk drives with some software.
