Greetings and Happy Thanksgiving to everyone!

I have a new laptop, but it doesnt have a lot of space. There are also many volumes of RTs that I will never use, and they take up valuable space on my HD and Im sure slow down the program when searching for the right RT. Also, I re downloaded all the RTs from the Update manager, the folder is currently 77GB.
I would like to do 2 things>
1. Delete the uneeded RTs in the Download directory, then save the reamaining RTs on a 64GB Pen drive for backup.
2. Uninstall and delete RT volumes from the BIAB directory, since my focus is mainly Jazz and Latin, I will never need most of the Rock and Pop stuff.
Can anyone tell me the best way to do this......
Thanks so much,
Edward
