There are a couple of situations in which tracks may not scan into the library:
1. MediaMonkey only scans formats that it supports AND that have been
enabled for scanning. If you are trying to scan, for example, .shn files,
MediaMonkey will not find them by default. To fix this you need to
first install an input plugin for the format in question (if needed),
and then check off the format in the Add Folders dialog so that it is
2. If MediaMonkey's Virtual CD or Previews directory is
configured to use a folder that is within the Path that is normally
scanned (e.g. if your Music is in /My Music and your Virtual CD is
configured to be saved to /My Music/Virtual CD/) then MediaMonkey
scanning operations will not function correctly. The fix is to set the
Virtual CD / Previews directories to a path that isn't scanned.
3. Some NAS devices (notably Infrant hardware) seem to stall and/or fail
to scan some files due to network-related issues. In such cases, setting
the device's TCP MTU to 1492 and disabling jumbo frames on the device
may solve the problem.
