SQLite 3 Pro - Cannot delete database files

[AWK]

Hello,

In my software, the user can create new databases for new projects.
Now I'm trying to delete a project, so delete the database file.
But... It won't delete.
No pop-ups or anything, it just doesn't work!
I have first closed the database, even destroyed the SQLite object.
I have tried deleting it with the standard 'File' object and with the 'File folder' object.
I can't delete the file, but I really NEED to!

Please, someone, help me out!

Ps. I am using Windows 8, running under Parallels on a Macbook.

Oops, figured it out!

I also had the database-file open in a SQL-database-tool.
When I shut that off, my software removed the file without a problem!
