Sorry if this is posted before but I thought I will contribute back after the awesome help I've got here 
What I have is a Compact & Repair code specifically for split backends. I have tested this to be working with .accdb files and I am pretty sure it will be easy to modify to accomdate .mdb files.
The code will first check if the backend is opened by checking for a record locking file (.laccdb). If the that file doesn't exist we can be 99% sure the backend is not being opened and ready for a Compact & Repair!
The code will also create a backup of the original file so you can easily revert back if possible and it is also handy to see how much space you've saved
I've also built in basic error checking which can be improved upon.
I am running this on a remote server on a timed event so every night this code runs and tries to compact & repair the backends. I have a log file which keeps track of which process failed and which didn't
You will need to create a new module. I have called this "basCompactBE". Paste the code below in this new module :
This is an example of how I use this module :
