Changing the filenameand type before deletion.

Forums: 

Sometimes even the filename.ext can lead someone to something:

For instance if u r at a public netcafe and you downloaded work files to read/view, you might be able to bleach(delete them securely) them but the file name and extention will still lead to what u were working on.

For example:

Budget.xml
Microsoft offer.docx
Company new plans.ppt

If we renamed the files to random characters no-one will know what they were about. like:
xyz.123
abcd.efg
1234.xyz

That's my suggestion. So what do you think?

Thank you veyr much and best regards.

That's what the "overwrite file to hide contents" does. More specifically, it does this

1. Overwrite the contents
2. Truncate the file
3. Rename the file to gibberish
4. Delete the file
