> No, MP3tag does not compare data between different files only within the current file. You would have to run an export of data and find a program that can deal with the export and group the data according to your requirements.  
> Of course, there is always the sorting function in MP3tag and the possibility to load two (and more) folders from different locations and treat the data of those files.

Yes, Mp3tag allows visual comparing of tag-field content over one or more files and folders.  
And because Mp3tag can work with tag-field content within one file, there might be a way to do so.

1. Given are two folders with the same number of files and same musical content and so forth (identical album), in order to compare each file's set of tag-field content with each other complementary file.
2. Load Folder1 into Mp3tag, export all tag-field names and tag-field values into CSV text file, for example using Dano's tool "Mp3tagCompleteTags" or write your own export script for smaller output.
3. Edit the CSV text file and rename all tag-field names, for example by prepending a short prefix "NEW\_".
4. Load Folder2 into Mp3tag, import all data from the CSV text file into the files from Folder2.
5. In case you use an adapted column setup, you can do visual comparing the content of the tag-fields side by side in Mp3tag list view.
6. Additionally the Mp3tag scripting toolbox and actions are available to do automatic comparing.
7. After all comparing and updating is done, the helper tag-fields can be removed from the files.

Beside this proposal there is always the way to use an application like WinMerge to compare two text files, for example, compare the complete tag-info from files of Folder 1 with Folder2.
