Answering this query I think I am the best person. The company file that is missing or cannot be found in QuickBooks is a common problem for which I can provide the solution. I am Harry parker from a non-technical background who has troubleshot this problem that is why everyone can. You can choose “open the restore company” or use the “search” tool from the windows. This happens due to the renaming or moving of the file which causes this trouble. Check the error properly before going for a solution as all are different.
