When TOE downloads new orders, the order files are moved to the Supplier folder\FilesReceived\Processed\2023... folders. If that file path length including the file name exceeds 250 it takes the path upto length 250 and it causes the error file path not found. This usually happens when TOE is running from a virtual store.
for ex: File path C:\Users\AAAA-User\AppData\Local\VirtualStore\Program Files (x86)\The Order Exchange\The Order Exchange\eeebc666-9c32-4ce4-80f4-b73ddcf5ad6c\BUNNINGS\FilesReceived\Processed\2023\03\21\9377779267899.202303210121429818096-6A003DF5FB02814897529CB54DE65490.dat
In this instance we need to disable virtual store.
This should fix the issue, but after the virtual store is disabled if TOE app is still going to start in virtual store path, TOE folders should move from program files to C:\\Users.
