How do I prevent the access database from modifying and saving itself upon open?
<p>When working with an Access .accdb, every time I open the file, I see that the 'date modified' in the filesystem changes to now. This makes me nervous. I want it to stop.</p>

<p>I can't be the only person who has ever saved a working db, and opened it a few weeks or months later to an error. Sure, I probably have backups, and backups to my backups, and table data saved separately from my code, and version history taking up multiple gigabytes of the filesystem or in emails or where ever... but it still makes my heart jump a little whenever I see the date modified update on open, when I haven't touched the DB in some time.</p>

<p>Have I flipped a switch somewhere that makes it do this? Is this expected behavior? How can I stop it?</p>

<p>To replicate this, create a new accdb, save and close. Put something in it, nothing, or close it only a second after creating it. Open an windows explorer for the directory the accdb is saved in, and note the date modified value. Open the file at least a minute after the displayed date modified file. alt-tab back to the explorer window, and you see the date modified has changed. </p>
