Hi,

I have made a database in Access 2010.
I understand that 2010 and 2007 use the same format .accdb? yet when i try to open the db in access 2007 i just get a message saying "unrecognized file format"

any ideas on what may be causing this?

Thanks for reading

There are certain features in 2010 that will prevent it opening in 2007.

Details of specific feature incompatibiltiy can be found here:

Try creating a blank A2007 accdb, then importing all objects from the A2010 accdb (except linked tables) into the A2007 accdb.

Thanks for that.
..in table 1 on the page you sent me i think its "Access 2010 Encryption Compliance" because its the one that stops the database from opening. (i have checked the database sort order and its set to General - Legacy)

how do i check / change the encryption?

Also see the attached warning i get when about to open the database (just after converting to 2007)
Do you know what links are being referred to and how do i change them to 2007?

@DatabaseMX: sorry you must have commented while i was writing mine..
when you say linked tables - do you mean tables with relationships or tables that are populated from other tables? ..because in the latter i have used regular SQL..why does 2007 have a problem with it?

"when you say linked tables"
I mean if you have a Front End 'linked' to tables in a Back End (aka 'split' configuration), don't import the links.  Relink after you import all other objects.

I you only have a Single accdb, then ignore that part.  And yes, do ... import any relationships in this case.

Sorry, I thought that might work.  It sounds like it's pretty much what carl_tawn posted ...
