Well with the windows upgrades - Microsoft has moved/backed up (for how long who knows) the files previously in the "current folder" where current exports are.
I'm sure they will be lost once MS decides it time to get rid of Windows.Old folder.
For example, I thought I lost of bunch of exports, but found them here:
C:\Windows.old\Users\yourusername\AppData\Local\Microsoft\Windows\INetCache\Virtualized\C\Users\yourusername\Desktop
