I'm not sure if a query like this has been posted earlier. If it has been, my apologies. I just downloaded MP3tag yesterday, but I can't seem to find my way around it. This is my requirement. I have 10,000+ files with the title tag... 0001 Genesis.01 0002 Genesis.02 0003 Genesis.03 . . . 10001 Matthew.01 10002 Matthew.02 10003 Matthew.03 . . . 10239 Revelations.01 10240 Revelations.02 10241 Revelations.03 I want to rename the title tag as follows: Genesis 1 Genesis 2 Genesis 3 . . . Matthew 1 Matthew 2 Matthew 3 . . . Revelations 1 Revelations 2 Revelations 3 I guess I may have to rename it in sets. When renamed I want to eliminate the 4 digit number in the beginning and I would like to remove the dot '.' after the name of the book. Looking forward for some enlightenment. If you think there is another post or thread where I could learn about this please do guide me there. Thank you... ---
