My db is on a network. When a db is opened the ldb file appears and when the db is closed, the ldb file SHOULD disappear. On occasion I have deleted the ldb file with no problem and sometimes I get a "file sharing violation" message. Do I presume this means the db IS being used? Also, if the ldb exists can multiple users still enter and save information to the same file. It does worry me a bit. cheers.
