Mikrotik lack of space or full drive and the fix
This one is a tricky bug that I've ran into. If you hit this, when you go to Files, you will see much more used space than what you're using. Often not enough unused space to upgrade. Here's how to fix it. You need the fix_space.npk file. It's currently hosted here: https://www.mikrotik.com/download/share/fix_space.npk I mirrored it here if it disappears: http://s000.tinyupload.com/index.php?file_id=34175859663734277043 Use it like a normal upgrade. Just put/drag it into your files then reboot your Mikrotik router. After the reboot you'll see your free space is normal.
