i saved sage files on my 32gb memory stick but when i put it back in the computer or another computer it cant open it and it says it needs to know what program created it , anybody help me out ??
Can you copy the files from the pen drive to the hard drive? Is it possible the pen drive is write protected? Some software I use won't even read if the pen drive is protected.
You need to eliminate if the pen drive or the files are at fault.
Then I'd say the pen drive is knackered. The files on your hard drive. Do they show the sage icon and do they look fine before you open them? Try the rename trick on those too.
