multiple account downloaded discs

[santojmezzaroba]

recently I purchased HOSTER and a portable PC. A good friend assisted in loading a number of My cdg discs onto the hard drive. I continued loading
cdg discs. I now realize that He used a different account than I and I am looking to consolidate both efforts into one base on the hard drive. It would be very
time consuming if I had to re-load all the discs. can it be done and how.
