I was saving my raw MPX files with the corresponding point file and BMP files on my desktop. Then I copied all the files on my harddrive and deleted the folders on my desktop. And now I cannot reopen the raw MPX files anymore. I always get an error that a file required for opening cannot be found in its original location. But if I put them back to the original location (on the desktop, same path) it still does not open the original MPX file. What should we do to open the original files?
