Seeding the deleted but not owerwritted files, to get extra healt for the files without wasting this resources

**Is your feature request related to a problem? Please describe.**

When a user delete a file from a storage device HDD,SSD,Memory Cards ETC. Only the icon will be deleted, but the file is still available on the device until it is completely overwritten with another file. It is possible this way to seed deleted files and get extra health an existing unused one powerful resource without using extra another resources in any device. These files in many case are still available long time after deletion.From low storage capacity mobile, and high capacity devices we can double the seed capacity this way.This is currently a wasted free huge storage.

**Describe the solution you'd like**

A clear and concise description of what you want to happen.
A seeded deleted files window,with a delete illegal malicious content button.And a button what only not use this seed function when the user delete a file because its illegal,virus.And simple extra menu insaide the files menu seeded deleted files.Where correctly written this files are deleted from your disk,not use your disk space,seeded, and please only delete some files if the file malicious or illegal.

**Describe alternatives you've considered**

File restoring programs widely use this option.There are not many P2P programs like ZeroNet which could take advantage of this. With darknet programs like I2P,Freenet such an option can be problematic.Similar working P2P decentralized web hosting program as ZeroNet which could take advantage of this to my knowledge not exit yet. But on a similar decentralized P2P web hosting platform,who can take advantage of this gaining a significant advantage over its competitors.

The issue names no files, tests, or entry points. Start by clarifying how deleted-file seeding should interact with storage and malicious or illegal-content deletion; done would require an agreed design and acceptance criteria.
