Certain tags are not written with cover art when I use the action: %_filename%.jpg
I have checked that the files in question do not have ' or [ ] characters. There seems to be no logical explaination. Out of 2000 files in the same folder, 30 or so are simply not written and the error says:
Import cover from file "%_filename%.jpg": File D:\Music\blah - blah.jpg cannot be accessed.
Yet, if I go to each file and add the art manually it works
I'm having the same issue. Since only a few of the tracks in several albums were missing cover art, I ran the action "Export Cover Art To File: folder.jpg". When running "Import Cover Art from File: folder.jpg" it states that it cannot be accessed.
There are no special characters in the paths, and there are no stray spaces in either of the parameters.
If I run a Quick Action -> Import Cover Art from File and manually browse to folder.jpg (typing produces the same error), it will apply.
It sounds like a variance in the spellings or the characters, but there are none.
iRelevntRequiem, ... hmm ... as you stated ... there was human interaction envolved ... in this case this leaded to an uncorrect filename with a correct file extension.
If I remember well ... this is a long time known situation and reason for a lot of lost time for debugging. Because Mp3tag can only export a picture as of filetype jpg, it handles the export process by adding the filetype automatically to the result of the given format string.
If the user had added a little deliberate some text to the format string, then the whole process of exporting and importing cannot be done successfully, when the applied format strings for export and import respectively their result values are not identical. So there are different filename strings, which leads to the system error message that the file cannot be accessed.
There are some related postings in the forum, the Mp3tag manual has no special note about this trap, but should have.
What do we learn?
The handling of Mp3tag export and import actions is not working fully symmetrical.
On export the user is not allowed to set a file extension.
On import the user has to code the file extension.
A user of Windows Explorer should always enable the display of the file extension.
