There is another option that allows updates from the same financial institutions on separate computers thus your able to use 2 computers for the same file. The file names are just different. The only caveat is that any manual entry on 1 computer will need to be manually added on the other computer.
Copy the file from computer one to the second computer and then change the name of the file (just add a 1 at the end of the file name) on the second computer. You will be able to update each computer from the same financial institutions. This way you basically have 2 different file names accessing the same financial institutions.
I have done this for a long time because I want 2 identical computers in case one computer suddenly crashes. When I do an OSU I do it on both computers generally on the same day but can be done on different days and any manual data entry or changes must be made manually on both computers so the data in the files agrees between both computers.
MAKE A BACKUP COPY OF YOUR FILE BEFORE TRYING THIS………
