WWBL,
"Reset" clears the database files. The remaining pieces that don't get erased are in the TXT files. Depending on what you want to do, selective deletions of the TXT fles will, as Scott said, create new, empty ones.
Best thing to do since we're not sure what you want to keep and what you don't, is to double click on each TXT file which will open it in Notepad. If it isn't what you want to keep, delete the file - if it is just leave it
