How we tested the permanent file erasers

Before testing each file shredder, we created an empty folder on our test computer. Then, we placed lots of different files inside it. In total, the folder contained 2.66 GB of data in 123 files, with various file formats: bmp, cur, docx, jpg, mkv, mp3, pdf, png, txt, and xlsx.

Next, we used every file shredding app from our roundup, to wipe everything inside this folder. For each of the shredding programs, we used the most complex erasing method it offered. We also noted how many erasing algorithms each app offers and how easy it is to use. Then, when all our test files were deleted and securely overwritten, we ran Recuva to check if any of the deleted files could still be recovered.

We repeated all these steps for each file shredding app that we tested. We chose the apps you see below because they are free and also popular. We did not want to include commercial software, as not many home users are willing to spend money on such programs.

1. Eraser

Eraser is a small app that can securely delete files, folders, unused disk space or even entire drives. To use Eraser, you have to download and install it. When done, it automatically adds secure delete options to the Windows right-click menu.

In addition to the contextual menu options, Eraser's interface also allows you to create scheduled erasing tasks. This feature is handy in case you work with data that you want to be wiped out regularly.

While it supports 13 different erasure methods, the one it uses by default is the Gutmann standard. This method overwrites the deleted files 35 times, which means that, depending on the number of files you delete, the process might take a while.

Now it was time to check how well Eraser performed. So we ran Recuva on the wiped folder. The result was that none of the deleted files could be recovered.

2. Alternate File Shredder

Alternate File Shredder is a small app that lets you permanently delete files. Its interface is simple and easy to understand and, if you select this option during its install process, the app also adds a Send to File Shredder erasing option to the right-click menu from Windows. Alternate File Shredder lets you delete both individual files and entire folders.

Alternate File Shredder offers only one erasing method: random data writing. However, you can choose the number of times the deleted files are overwritten. You can also choose to shred file names, so not only the contents of the files get erased, but also their names.

When the erase process was completed, we started Recuva and checked if any of the files were recoverable. Recuva was able to find 113 of the deleted files and could recover 109 of them. However, none of the recovered files could be used, as they were all corrupted.

3. Moo0 File Shredder

Moo0 File Shredder is a lightweight application with a minimalist user interface. Once you launch it, all you have to do is drag and drop any file or folder that you want to delete permanently. Unfortunately, Moo0 File Shredder does not add any erasing option to Windows' right-click menus, and it also tries to bundle some "Additional Free Tools" during its installation. Make sure you uncheck this option during the installation.

By default, the interface lets you select the erasing method to be used. If you press the Detailed Description button, the program's window expands and lets you see more details about each of the methods available. Moo0 File Shredder offers 4 erasing algorithms, including Gutmann.

4. Freeraser

However, if you right-click on it, a contextual menu opens, offering you more options. We would have also liked if Freeraser had an erase option in Windows' contextual menus. Unfortunately, it does not.

Common sense and the official documentation tells us that to delete files or folders; it suffices to drag and drop such items onto Freeraser's icon. However, on our Windows 10 laptop this feature did not work, so we had to use the app's menu to select the set of files we wanted to wipe. Once you select the files to be wiped and confirm the action, Freeraser's bin changes so that you know the erasing process was started. Freeraser offers 3 shredding algorithms, including the 35 passes, Gutmann method.

If you look at the numbers and features each program offers; the winner immediately stands out. Out of all the free apps that we tested in this roundup, Eraser is the best file shredder.

When compared to the other apps, Eraser offers one of the most extensive selections of erasure algorithms and the best user interface, as well as more configuration options. All the other programs are lagging when compared to Eraser. The only one that offers even more algorithms is WipeFile, but it is no match to Eraser regarding the user interface. The others do not even come close to the number of erasing methods included, even if some of them offer the best ones on this line of work: the Gutmann and the DoD algorithms.

Others work well enough but lack contextual menu options (including WipeFile), which do the whole erasing thing much faster and more comfortable.

Conclusion

We hope that our free file shredders roundup was helpful. Even if you do not use such a program on a regular basis, it does not hurt to have one ready on your Windows device. You never know when you need to make sure that some files are deleted permanently, with no chance of recovery. Even more so, if you are working on a computer that you share with others.
