What will happen if two developers were working on different sheets of a single document and they were trying to save that document(already in the common share folder) at once???? Will all the changes made by both the dveleopers will be saved ?
( Lets Consider "A" be the document name and " A1 "and " A2 " be the Sheet names in that document and User1 is working on A1 and User2 is working on A2 . )
Assuming that user1 and user2 had the same copy of the app before amendments were made, one user would lose their amendments. There is a risk that the second user to save will overwrite the first user and probably produce a warning message. I don't believe QV is capable of automatically merging simultanous edits.
