UBB.threads PHP Forum Software Community Forums UBB.threads Installation and Upgrade Support At the "Updating database to version: 7.2.2" Step

I had to stop the last step manually.

After checking things over things seem to be working OK, however, I have way too much space taken up, therefore, I did a check and discovered three MYSQL files that I think can be deleted:

#sql-1888_9300.MYD
#sql-1888_9300.MYI
#sql-1888_9300.frm

As I think they are some sort of back-up or something in relaiton to the upgrade, is it OK for me to delete these three files?
