Can't find my default AI file to remove

Hi all,
Im trying to remove the default ai in FS9, i know that im supposed to delete/rename a file in the scenery/world/scenery folder called something like Traffic(some numbers).bgl but there isnt one there :-?
If i open up the TTools programme, it allows me to decompile a .bgl file called traffic030528.bgl (which i think is the default traffic one) as well as my other ai files but that file isnt in the folder.
Any ideas guys
