Not necessarily...If the size of the mdb file is large due to tables with a large amount of records, then of course, the performance will slow down a bit for access to larger tables. If the size is large due to not compacting regularly, or due to just having very many tables and objects, but the tables have a low record count, then the size of the .mdb file should not affect table access adversly--however not compacting can cause other performance issues--the indexes get rebuilt in a compact, etc.<br>--Jim
