Check the files in that folder and make sure they are not set for read only.
(Right click and and then properties)

One bit of further info for the devs is that only the MM created/synced playlists are disappearing :o - I created a playlist using the stock Android music app and that remains after a phone restart, and is seen by MMA :-? Also to make it clear this particular problem has only occurred with this late...

Installed playlist backup as suggested - it would appear that when the monkey can see the playlists, so can playlist backup (under system playlists). On phone restart neither MM or playlist backup can find them so they are definitely being deleted :( Interesting fact I noticed was if I restored the ...

Using 0156 build with MM 1652 I noticed that on the recent upgrade that all of my playlists had disappeared. The associated tracks however were still on the phone. So I did a wifi sync and the playlists were downloaded ok Next day the playlists had disappeared again :-? Synced again - playlists down...

I appreciate the workaround, but one thing I like about MM is that I can have the details and also click on the album art and make it bigger for close-up viewing. For me, checking out the album art goes hand in hand with listening to an album. Agreed - whilst the workaround is fine on my new lappie...

Thanks for that Ludek - a small adjustment to my window size and all is well again

Either in this version or in a recent other version the functionality of left clicking the art work to get a full size preview seems to have broken :( Was this by design :-? - I used to find this very helpful in quickly seeing the quality (or lack of) of my album artwork. I tested using an earlier b...

Having problems with 5.1 :( When I try to extract and resize external image (option 4) the file I am trying to create (folder.jpg) is shown in blue and is not created :-? No problems with V5.0 which shows it in green as usual. Is there a new setting hiding somewhere or is it a buglet Having a simil...

That is exactly what auto organise files will do (ctrl R)
Just use something like in the mask
The monkey will display the results before making any changes so nasty surprises

If you are happy that your tags are good, make sure that you untick " Infer file properties " in Options/Library. That can give some odd :-? results at times and is better to leave that off. Remember the monkey will not change your tags unless you tell it to. What you see when looking at your files ...

The 'Lead artist(s)/Lead performer(s)/Soloist(s)/Performing group' is used for the main artist(s). They are seperated [sic] with the "/" character.

Just copy your MM.db file from the original to the new portable folder. That will bring over everything.
However any changes that you have done in the beta and not updated in the original may get lost so make sure the original is up to date.

First let me say Im all for searching a forum for an answer before posting a question. Searching your RegExp Find & Replace add-on may have been useful. 1) I want it to add a zero at the beginning of my track #'s and I cant seem to figure out how to get it to do it (1-9) etc Preset 81"Add leading z...

Rather then answer your questions directly I will relate on how I use the monkey. Like you I have a fairly large music library (1.3 TB) on a home server and yes scanning that lot takes ages. All my new music goes into 1 directory, which is the only one scanned by the monkey on startup. All the other...

It is - just downloaded
