database clean up?

[jbp.imperial]

when looking at my ipod in disk mode on the computer i click on .rockbox there are many files one is labeled database_idx.tcd

there are 7 other database files next to this one.  

one example is database_0.tcd

is it possible to delete these other database files to clean up the disk?

Of course it is possible to delete them, just don't expect your database to be in working order without reinitializing (and then the tcd files will appear again).

To sum it up, don't delete them if you use the Database.
