Ok to remove/empty unused sql authorizenet?

I'm making space on my server and don't want to cause problems. I found a file /mysql/DATABASE/authorizenet.MYD that is very large. It is 43mb and the 9th largest file/directory on my server.

I haven't used authorize.net in 2 years. Is it safe to empty this table?

Here is the whole path

var/lib/mysql/DATABASE/authorizenet.MYD

YOUR POST IS SERIOUSLY ALARMING!!!!

If you have no history in it which you need to keep, then you can truncate the table.

**BUT DO NOT EVER delete .MYD files by hand!!!!!!!! Seriously. YOU SHOULD NOT BE MUCKING AROUND IN THAT FOLDER AT ALL!!!!!!!!!
**If you're going to delete data associated with a given table, then make a solid reliable backup and truncate the table using phpMyAdmin. DO NOT DELETE MYSQL DATABASE FILES DIRECTLY!!!!!!! EVER!!!!!!

10-4. I wouldn't delete any file associated with the database. I know that would be a major FAIL. I just put the path there because I wasn't really sure what I was looking it. Thanks for clearing it up.
