Sorry about the mixup on my part. I've been playing with the files all morning and it is great. I've changed files on the BP and PC and both were updated correctly. I doubled the size of one text file on the PC and it was updated but I had to pop the batteries out while reading that particular file. The BP locked up and the reset keys did not do a thing. Once I popped the batteries out and back in again it worked just fine. This is a great feature and I can already see many uses for it in my daily life. Thanks, Larry
