By transfer, do you mean move them or just copy them? You can certainly put a second drive in another PC temporarily for this purpose. You cannot copy entire programs this way but you can copy such as text, audio/video, picture files and those you have created with programs on the other PC. The other PC must have the ability to open the files you copied or they would be of little value. Hope this answers your question.
I have a computer running Win ME. I want to transfer the files from that hard drive to a computer running Win 2000. Is it possable to take the HD from the ME computer and put it in the 2000 computer as a 2nd drive? I would then copy the files to the drive that has 2000 installed on it. I would then put the ME drive back in the computer that it was in first. Will all the programs work ok?
