You are approaching the limit on the number of attachments you can have on a board.

Question

I've had this warning come up:

You are approaching the limit on the number of attachments you can have on a board. Please remove any attachments which are unnecessary.

What's the best way to view old archived cards and delete those? They will be years old at this point.

If you copy the board, then the new board will have all your active cards (but will not copy over the archived cards), which should automatically free up the space.
