2 GB in a single ACCDB.

But keep in mind that if you use a Split architecture ... Data tables only in a Common Back End db ... and everything else in Front End db ... you effectively can create more space of sorts.

Patrick MatthewsCommented:
Carrying on with that theme, a split architecture can have >1 "back end".  So, while each MDB / ACCDB file is limited to 2 GB, the entire app with all of its data stores can be considerably larger.

That said, I think it's tempting fate to have files that get much north of 1 GB.  At that stage, one should be thinking about upsizing to a SQL Server back end.

When an Access db approaches the 2GB limit ... it's sort of like approaching a Black Hole.

2GB is the limit, but as Mx said, you can split things.  In fact you can take that even further by putting one table in each DB, so the limit really is a 2GB table.

However if you do that, the only problem is that you cannot enforce relationships across the DB's.

  Also keep in mind that 2GB is not all that big given that all text is stored in unicode, which is 2 bytes per character.
