%APPDATA%\Microsoft\Windows\Recent

%APPDATA%\Microsoft\Windows\Recent seems to store .lnk files that point to recently used files (aka Recent Items ?)
In cmd.exe, a quick access (?) to this folder can be opened like so:
C:\> %windir%\explorer.exe shell:::{4564b25e-30cd-4787-82ba-39e73a750b14}

PowerShell script to show recent items

The following PowerShell script extracts the target paths from the .lnk files found in the recent files folderc
set-strictMode -version latest

$sh = new-object -comObject wScript.shell

get-childItem $env:appdata\Microsoft\Windows\Recent -filter *.lnk |
sort-object lastAccessTime                                        |
foreach-object {

   $lnk = $sh.createShortcut( $_.fullName )

   $tgt = $lnk.targetPath

   if ($tgt) { 

     if ( test-path $tgt -pathType leaf ) {
        write-host "$($_.lastAccessTime.toString('yyyy-MM-dd HH:mm:ss'))   $($lnk.targetPath)"
     }

   }
}
