Hello dear people!
Very new to this tool and I have a couple of questions if possible.
First of all, I am interested in knowing whether the following formats are supported, since I didn't find them in the list of the supported ones: fdx, aac, m3u, m4u
Second question: is exiftool still able to identify at least the main metadata (dimensions and format) of an image even when the exif section is missing from the item itself?

Yes. You can easily check this out by removing all data from a file (
-All=) and then running exiftool again.
C:\>exiftool -G1 -a -s -*width* -*height* -*size* y:\!temp\Test4.jpg
[File] ImageWidth : 1749
[File] ImageHeight : 1205
[System] FileSize : 445 kB
[Composite] ImageSize : 1749x1205
First question: Try running ExifTool on these files to see. ExifTool may read metadata from them if they are based on a supported format.

I believe m3u and m4u are simply text files and will probably show up as such.
I only have 1 aac file and it shows up as unknown.

Very sorry for the late reply and thanks everyone!
Running exiftool on a file as Phil suggested indeed is a way to see whether a format is supported or not. However some base files, in my experience, may fall into another format parser.For example (don't get what I say for granted cause I don't remember if these 2 were exactly the formats) I experienced a parser where .mov files were not supported and they were falling into the .mp3 scenario. So, something was coming back but not the whole thing nor correct. That's why I was curious to know if those formats were really supported ;D And I thank you all for the precious answers! :)

That seems unlikely, as the formats are pretty different. Maybe it was returned as m4a or m4v?
If a MOV files was identified as an MP3, Phil would probably want to see an example in order to fix the problem.
The identification of MP3 is weak, so it is certainly possible that unknown files may be identified as MP3. But MP3 is the worst one I think. Most other file formats have stronger magic numbers.
This is the order in which ExifTool tests the file format. MP3 is near the end of the list so that other file formats with stronger magic numbers will be tested first.
