What folders (files in folders) are deleted when "entering sleep"? Can these be created?

Question

Encryption

I use an encrypting safe, but unfortunately, the software for the safe does not open several files at once. Uncomfortable. You have to transfer files to an unprotected area of ​​\u200b\u200bthe disk. And where to transfer so that no one else sees them later. In general, you need to find a temporary folder or a program that deletes the folder after entering sleep / logging out of the account / restarting the computer.
Thanks in advance. I will be glad to any answer.
OS: Windows 10

Answer 1

In theory, when you reboot / shutdown the user, it first logs out, so:
Make a batch file or powershell script that will delete files and put it in the
User Configuration\Windows Settings\Scripts\Logoff
Computer Configuration\Windows Settings\Scripts\Shutdown policy

Answer 2

or mount a disk of the same veracrypt?
