I wanted to run ERUNT and then save the back up to a USB drive. Even finding the USB drive on screen was difficult. No more nice WIN 7 layout of all drives!!! When I tell Erunt to save the backup registry all I get is an error MESSAGE. How do i ACCOMPLISH this or is it not possible?I have my Win 10 configured to run like Windows 7. First you NEED to see if you transfer an ordinary file or picture to your USB stick. If that works , save your Erunt file to your computer and then SEND it to your USB drive.Speaking of Windows 10 having issues with USB sticks, I have a problem, too. I've recently bought a 32gb USB stick and tried to PUT a 5gb movie on it. To no avail. Every time I try, I get an error message saying that the file is too big. I checked, there are actually 30+ free gigabytes on the stick. I've tried to put 5, 10, 20 gb's worth of other files on that stick, and it works. Still, I can't copy that one movie there. What should I do?If the Drive is formatted as Fat32 the largest file you can save is 4 GB. You need to format it in NTFS if you need to save single files larger than 4GB to the pen drive.
