Depends what files you mean. There are 3 general classifications: Operating System files (Windows files), Applications files (Program files such as MS Office), Data files (Word documents, Excel files, photos). When you say Data, I assume you mean only the 3rd classification. If, yes, they can copied in a number of different way, depends on how many and large they are. You can copy them to a floppy disk, CD, or network the 2 computers and copy from one to the other.
