Every user defined will have their own "My Documents" folder. You'll need to look in the drive's root for "Documents and Settings" and see if you can find the right user. As well, if you know the file extension(s) used, you should be able to search the drive that way.
I've just setup a new computer for my olds (winxp Pro, 160Gb SATA HDD, 1Gig RAM, SATA DVD Writer. I was planning to copy files from the old PC to an external drive and transfer to the new PC. In the meantime my father-inlaw tpulled the power cord on the old PC (Winxp Home OEM, 40GB HDD, 256Mb RAM) as it had frozen and wouldn't respond. Now the old machine won't even turn on. As I didn't have spare power supply to try I installed the old IDE drive as a slave thinking I could copy them across. I can see the old drive in My Computer and access it but when you look in My Documents there's only a My Pictures folder with nothing in it where there should be photos yet the Programmes folder has files in it. Why arent they missing too?The old drive has been renamed as the "E" drive. Is this why I can't see the files in My Documents because they would have saved under"C". The old drive still has XP Home installed in a hidden partition. Drive properties shows 33Gb of space with 23Gb available so something is using the space. I'd appreciate any help you can give, Cheers
