I have the same problem with MM4 sometimes not picking up files in watched folders. It will pick up some but not others in the same folder. I've also had it miss videos that I've converted with the "Add files to library " box checked.

As stated the files might be in a different Collection so check the Classical Music Collection or the Entire Library Collection (which lists all files in Library): http://www.mediamonkey.com/wiki/index.php/WebHelp:Playback_Rules/4.0

Auto-Tag from Web doesn't work in MediaMonkey 3: http://www.mediamonkey.com/forum/viewtopic.php?f=1&t=61578

And for the error send a debug log (step 4b) to support: http://www.mediamonkey.com/forum/viewtopic.php?f=1&t=69

[quote="jjstccean"]I've experienced the same problem, MM ver 4.01 does not add certain folders with mp3's, flac's, etc - uncanny, it adds all the rest of my music folders - my only solution to this problem was: I've uninstalled ver 4 and re-installed the latest version I have available: 3.2.5.1306 - this version adds all my music folders and files without any errors.[/quote]
lol, exactly that's the problem. just now i tried to install 4.0.1 and it asked me to delete files that are no longer available in the library (and MM showed the exact files, that were played in version 3 with out any problems but which i falild to add to the MM 4 library)

By the way, I appreciate your work, connected with the evolution of MM, but still I must admit that I really like MM 3.x much and much more. The only trouble with that player - is that lately it refuses to download the music info from amazon (it says - 0 results). Maybe somehow there is a way to insert this fixed search from MM 4.0 to 3.0 so that Ctrl+L command worked properly?

By the way, there was always this problem, at any version of MM and on different computers. It somehow connected with putting the MM to tray.

@jjstccean, did you check the Entire Library node as this is where everyone else finds their missing tracks?

After submitting the page doesn't load, i'll try several times more a bit later. THank you for your support anyway.

Upload it and add the link to download to a support ticket: http://www.mediamonkey.com/support/index.php?_m=tickets&_a=submit

pardon -* it was not damaged.*

Well it was damaged, it played by MM perfectly, though it didn't want it to be added to the library. Other players didn't have any problems too. File is mp3 256 vbr. I can upload it just for an experiment.

If opening the file from Windows Explorer in MediaMonkey fails it is most likely an unsupported file. What file type is the file?

Just installed MM 3.2.5 - it has found the file immediately.
MM 4.0 is still full of bugs, guys.

[quote="Lowlander"]You can add specific files to MediaMonkey by drag & dropping them onto a main Collection node. Otherwise as plenty of posts explain any files that are set to hidden or stored in the VirtualCD/Previews/UPnP Cache folder will be ignored during Add/Rescan Files/File Monitor.[/quote]

The file is not hidden or not placed in a folder where VirualCD, Previews and etc are stored. I tried to drag and drop it right to the player, as well as start playing it by the player, and also tried to open it by Ctrl+O command, tried to change the directory/filename of the music file, and of course i tried to re-scan the music database (manually and automatically) - the result is 0.
A few days ago same thing happened - i've added the whole album in mp3 - but MM showed only 5 of 99 tracks. I didn't like the music, so I didn't consider that as a problem. But now....

Same problem here, I would same MM refuses to add only certain files (I can't imagine why), though the directory - where all music files are stored - is same.
Kinda of bug, I wish I could use MM 3.0, it was much better.

Make sure files aren't set to hidden (MediaMonkey ignores these) or that the Virtual CD or Previews folder is set to the folder you're scanning (contents of these folders is ignored).

1) When adding files to a playlist the files aren't moved. Are you sure Tools > Options > Auto-Organize doesn't contain organization rules that might be applied?

2) It seems MediaMonkey is respecting that the files weren't in the database and thus when making modifications it still doesn't add them to the database (after all you're just renaming/moving files on your PC).
