I have 2 computers, Win10 Pro & WinXP SP-3. For some time now, I've been transferring files back & forth between them on my network. All of a sudden, this happens:
1. I'm on the Win10 machine & open a particular document folder named Bridge in Windows Explorer.
2. While on the Win10 machine, I open the networked Bridge folder (the folder on my XP machine) in Windows Explorer.
2. I try to copy 1 or 2 specific pdf files from to or from the Bridge XP folder.
3. I get the following messages:
Transfer of 2 pdf files between computers now requires permission-image.png Transfer of 2 pdf files between computers now requires permission-image.png

This only happens with 2 particular pdf files that I recently downloaded & does not happen when I'm on my WinXP machine (I can transfer both ways from there). Also, it only seems to happen with the Bridge folder on WinXP.

How can I change this to prevent these two messages from popping up when I try to transfer?
