This tweak makes the ‘My Documents’ folder on the Start Menu into a cascading folder, which then give you direct access to sub-folders without having to open the main ‘My Documents’ directory first.
Open your registry and find the key mentioned below.
Create a new string value, or modify the the existing value, named ‘CascadeMyDocuments’. Modify the value to equal ‘YES’ to enable cascading or ‘NO’ to disable it.
Exit your registry and log off for the changes to take effect.
Note: By using the same key except under the [HKEY_LOCAL_MACHINE] tree the tweak can be enforced system wide, instead of only user based.
Key: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
Value Name: CascadeMyDocuments
Data Type: REG_SZ
Data: YES or NO
