Win XP: Folder settings

By default, Windows XP remembers the last 400 folder settings. After 400, it's supposed to discard the oldest settings, so that it always remembers the most recent 400. In some cases, however, it just stops remembering new settings when the number of settings hits 400. Note that the steps that follow will clear all your old folder settings so Windows XP can remember more, and this method also raises the limit higher than 400.
1. Launch REGEDIT from the Start menu's Run dialog.
2. Navigate to the Registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell. If this key is not present, skip to step 8.
3. If a subkey named BagMRU is present, delete the entire subkey.
4. If a subkey named Bags is present, delete the entire subkey.
5. Look for a value named BagMRU Size (with a space between BagMRU and Size).
6. If this value is not present, select New | DWORD Value from the Edit menu and name the new value
BagMRU Size.
7. Double-click on the BagMRU Size value, choose Decimal, and enter the desired number of folder settings for Win XP to remember (for example, 1,000).
8. Navigate to the Registry key HKEY_ CURRENT_USER\Software\Microsoft\ Windows\ShellNoRoam. If present, repeat steps 3 through 7.
