[Parody]

The list of Most Recently Used files is stored in your Hero Lab preferences file in Hero Lab's data folder. In Windows Vista and higher this is likely:

C:\ProgramData\Hero Lab\herolab.prefs

(Note that ProgramData is a hidden folder.)


With Hero Lab closed, open that file with a text editor and delete the lines that start with:

<preference name="MRU List

Hope this helps.
