CleanMyPC's Shredder module is designed to secure the process of removing files from your computer and make their restore impossible. If you wonder why you would need it, here's the answer: when you just drop a file to the Recycle Bin, its data remains on the disk even after the Bin is emptied. It happens because, actually, you don't erase the data itself but rather its address on the disk. Therefore, there's a chance that ﬁles removed via the Recycle Bin may be brought back by some third-party recovery software.
Meanwhile Shredder allows you to choose an appropriate security level of the cleanup operation. Depending on the selected option, the data of the file is erased and then re-written with zeroes one, two, or three times, which is enough to delete the file for good. For example, you can set the highest security level for deleting some very sensitive information like financial docs or credentials.
That's how it works:
- Open the Shredder module of CleanMyPC.
- Do any of the following:
- Click Choose Files or Choose Folder and navigate to ﬁles or folders you want to remove.
- Right-click a ﬁle or folder you want to remove and choose Secure Erase by CleanMyPC from the shortcut menu.
- Select ﬁles or folder you want to remove and drag them to the lower-right corner of any Windows screen.
- Click the info (i) sign in the lower-right corner of the CleanMyPC window and a slider to set a security level. You can choose any of the following options:
By default, CleanMyPC applies maximum security level.
- Minimum security level - one-time rewrite of a ﬁle with zeroes.
- Medium security level - double rewrite of a ﬁle with zeroes.
- Maximum security level - triple rewrite of a ﬁle with zeroes.
- Click Erase.
Note that secure erase usually takes more time than a regular cleanup, but you'll be sure nothing would ever raise your files to the surface.
