Then in the tab View untick Hide protected operating system files (Recommended), Give Apply and then OK.
In each partition you will notice that the system appeared more system folders, Including $ RECYCLE.BIN (or RECYCLER, according to Windows). Copy that folder ($ RECYCLE.BIN) anywhere and rename it as you wish. In that folder put all files you want to keep Secrets.
After you have ensured that you do not forget any files, follow the same steps as before, and check back option Hide protected operating system files.
