Shellbags are a set of Windows registry keys that contain details about a user-viewed folder, such as its size, position, thumbnail, and timestamps. Typically Shellbag information is created for folders that have been opened and closed with Windows File Explorer and default settings adjusted.

Shellbags are located in the following registry keys:

Windows XP

NTUSER.DAT\Software\Microsoft\Windows\Shell\Bags
NTUSER.DAT\Software\Microsoft\Windows\ShellNoRoam\BagMRU
