Vault: How are deleted files and file versions handled?

[Allnamesaretaken]

I’m using Kaspersky Total Security and would like to ask how well vaults retain the files that are put there. Original files, clouds or any other backup are not a concern here, just those that are on the vaults.

 

• Question 1a:

Where do the files go when they are deleted from a Kaspersky vault: Do they always remain on the encrypted volume until overwritten or do they get sent to the recycle bin of the particular drive that the vault is on?

E.g I have Kaspersky vault Y:\ on SDD D:\, would my deleted file remain on Y:\ or get sent to the Recycle Bin of D:\?

 

• Question 1b:

Would the hardware make any difference: I have vaults on SDD, HDD & USB flash drives (which I heard don’t have $Recycle.Bin).

 

• Question 3:

What happens when I delete a vault: Will anything that was deleted on the vault become unencrypted and recoverable all of a sudden?

...or is the encrypted vault and all the files that were on it (both deleted and undeleted) still there in the background, still encrypted (and recoverable as encrypted only) until overwritten?

 

• Question 4:

File versions stored outside the vault: Would Windows features like “Volume Shadow copy Service” (VSS) or “File history” keep versions of the files on a vault somewhere outside of the vault?

 

This clueless noob thanks you in advance! :)
