Can a access database be worked on at the same time with more than one person working on it

If the access file is on a network desktop space it can be worked on by numerous people at the same and the changes should synchronize when the file is saved.

Access is, by default a multiuser platform. If an app is going to be multi-user it NEEDS to be split between back end (tables) and front end (everything else). The back should be on a shared network drive, for optimum performance the front end shouls be on each users local drive.
