I have reviewed a number of posts and find no good way to do a "bulk remove" of filename to tag formulas. I name all of my music the same way so the tag to filename history is less of a problem, but after many thousands of files from different sources, that history is very large. To remove each entry individually is very time consuming and if one does not ultimately choose a format and actually do a change, you lose all of your previous removals. Just by looking over the posts, I come to the conclusion that an easier way to remove multiple history entries would be welcomed by a large number of users. Is there any configuration file that could be edited? Is there a way to select multiple history entries? Is this feature a possibility for a future release?
Thank you in advance for any help.
Yesterday I spent some time and individually removed a large number of tag formulas. My computer was rebooted overnight for an operating system upgrade. All of the tag history that I had removed was back again.
I'll add a modifier option (via [Shift] key) to the Remove from history menu item that will remove all items.
Maybe that's a little too secret?
How about a second menu item "Remove complete history" with a confirmation box.
Need confirmation box - if possible.
It would be good if you could sort the history.
Because the prog is so good I am sure many of us have large histories - sorting the strings would be a really good option.
Cheers
It is great that you can remove all history, but what would be better is to be able to remove multiple items while keeping some, such as when one uses the Control or Shift keys to pick multiple items. Sometime you want to keep 5-10 of 40 in the history and it is tedious to do it one by one. It should not be ALL or ONE item. One should be able to pick some from the list. Even if it was a .txt file one could edit outside of MP3tag.
If you already prepared to use an external text file, then you could maintain one that keeps your favourite masks (and even add a comment).
It would then be easy to delete the whole history and restore the favourite masks from the text file.
Did you know: if you have frequently used conversions, then you could keep them as an action of the type "Guess value" with the source %_FILENAME%. The target pattern follows the same syntax as the converter. There is no preview, though.
Thank you for this useful tip, Ohrenkino. It also solves a problem I have had, one that may be of interest to others.
Let's say I am using a Filename to Tag format like this: %year% - %title% - %artist% (%vocalist%) but the filename in question has no vocalist. In that case, Filename to Tag from the menu does not run (no preview, etc.). I have to use a different format for that file in a separate Convert operation from the menu: %year% - %title% - %artist%
However, using Guess Value in an Action with %year% - %title% - %artist% (%vocalist%) on a filename works, whether the vocalist data is present or not! Guess Value fills the first three fields and simply ignores the missing vocalist and the parentheses. Previously I had tried using brackets around the vocalist to do this but my experience was that Filename to Tag from the menu always fails with brackets.
So your suggestion to use Guess Value in an Action saves me from doing a separate menu conversion for the two cases, which is a very nice time saver.
I actually do this, probably on a previous suggestion by you. I am not that innovative. 
So is it possible or are you just pointing out the benefits of having this option available?
No, it's just a workaround. There is no text file to edit the command history.
