Here is a batch file to clear your game files created by scripts in the TWX Root folder after a game.

Unzip the contents. Put the ClearTWX.cmd file into your TWX Root folder and drag a shortcut to it out onto your desktop (for convenience).
Double click the shortcut to run the batch file.
It will ask for the game database name.
Enter the database name and it will display a list of the files it intends to delete and wait for your confirmation to continue or abort.
If the files in the TWX folder contain the game's database name in the filename they will be included in the list of files to be deleted.. this should mean that all the files (or at least most) connected to the game will be cleared.
It's a good idea when asked for a filename to create by a script to use a naming convention that includes the database name.. for instance. If your playing on Archys Server in game K.. i would use ArchyK as the database name. If i do an export of the warp data i would use a name such as archyk_warps.txt as the file name... or warps_archyk.txt.. etc. this way these files will be cleared as well..

There is a version of TWX that I think Maniac compiled that has a Rebang Button that does the same thing if interested might give him a shout. Works well been using it for a long time.
