I have changed my thinking on this as I am generating folders for my updated library for "total discs" when I move the folders however I do not see the need to create a subfolder for single disc albums, is there a way to calculate total discs (assuming that this field has no value) than deleting the discnumber field only if the totaldisc field returns a value where the album in question is not a single disc and to remove the totaldisc number from the discnumber field if it is greater than a single disc and simply put it into its own field?
Am sure from what I can see as I type that part of this request has already been addressed (Strip total disc number from discnumber field) but am looking to combine this if at all possible...
[In future, try to write shorter sentences, chopping the problem and what you want to say into pieces]
I also change my system, more than once, about many fields and the data itself that I want / need to see
I would suggest using a system where you actually put "1" to describe a release that had one disc / part / source / whatever. For the longest time I only was describing with numbers those releases that had more than 1- and it was [objectively] wrong approach
Currently I put the number of discs [or of "whatevers"] at the end of ALBUM tag field, right after the title of a given release [but that I view as being superior only in a subjective matter, in correlation to how I use different fields]
