I'm using W7 premium 64 bits. When I want to select the sub-directory of my Samsung tablet under Androïd, MP3tag reports "Uncorrect directory". I would say that from the MS explorer of my PC I able to browse the 400 MP3 files stored on my tablet stored in the same directory. I have installed MP3tag V.2.52 under the adminstrator's account.
From the file menu I got the same error message"no valid directory name", I'm using the same Windows account where the mp3tag has been installed: Administrator. May be because I try to open a folder from Androïd ? I don't think so because I'm able to browse the diretory from the MS Explorer...
As part of the research:
you could add a column in the windows explorer for "owner" and see whether the folder \media (also) has "Everyone" as owner and not only some strange string with letters and numbers.
You could then try to add the (Windows-) owner "Everyone" - and hope that the android then can still access the files.
I suspect that it is a problem with read/write access.
I'm not at home for the time being. I will try what you describe around 06:00 pm (France).For your info I got an ineresting reply from another member suspecting that Mp3tag doesn't support the MPC mode used by Android as connection mode, only USB is supported.... To be confirmed
Well, I cannot say anything about the behaviour of a smartphone with Android operating system.
Because your question offers a problem, I have never heard before, and which should not happen nowadays, it is worth to find out what is going on there.
I just want to clear the situation.
It seems that you interchange the folders \music\ and \media\ and the devices in your summary above, please check again.
There are no options in the Mp3tag "File" menu, there are only menu commands.
You have reported, that you can browse for folders and files using the Windows explorer in both folders \music\ and \media, in local device and remote device, without problems.
The system and you, the user, have access to both devices. That seems to be ok.
Mp3tag cannot browse for files, but only for folders.
You have reported, that you can ... "From Mp3tag v.2.52 ... browse my mp3 files located in the sub-directory \my music\ of my PC".
That cannot be true.
Browsing for files is quite not possible from within Mp3tag, because Mp3tag provides only a "Folder Open" dialog.
When the problem comes up "it doesn't work", you should tell us the correct error messages of the specific situation.
It could be that the folder /media/ is not a physical folder in the filesystem of the remote device, but sort of a logical shortcut, therefore try to find out the storage place, where the media files are stored physically on the smartphone device.
I would prefer that you test by yourself using a smartphone and correct me if necessary. May beyou will encounter the same problem. Anyway, I will wait for a couple of days on this forum with an idea or a solution. If no solution is found I wiil sadly uninstall the Mp3tag and try another one.
Oh well ...
Some more things to test: as WIndows Explorer allows to edit tags in its NTFS environment - does it also allow this on the smartphone?
Some Internet sources tell in the context of USB that it would be of advantage to set "USB debugging" to on. (Don't ask me where you find that option on the smartphone but it is supposed to be there).
And finally: if you altered your workflow so that you keep the master of your collection on a PC and sychronize it with the smartphone you could use merits of MP3tag. In respect to "backup" this would be the solution with more advantages ... a smartphone may be lost or get stolen ...
I completely agree with this. The files on your smartphone should be copies of files from a master library that you keep and maintain on a computer or file server. Although in most cases it is possible to have Mp3tag edit files on the device itself, it's not a very good long term plan.
