Hi all, im starting a new thread with a followup question based on garym's recommendation. As the title suggests im creating folder structures from my tags and am going for the structure of: For single or 2 disc albums: %Artist%/%Album%(with year(if applicable))/%track% - %title For albums with 3 or more discs: %Artist%/%Album%(with year(if applicable))/disc#/%track% - %title This is what ive got so far: C:\Music\%artist%\%album%$num(%track%,2) - %title% Just stuck with how to edit this to do what i want - hope i made this clear. Was also wondering if it is possible to detect if discs of the same album are called something different ie: disc1: SH1-sounds disc2: SH1-noise As in these are the same album but the discs are called something seperate so i want the album to be SH1 with 2 discs inside the folder called sounds and noise. Think this may be too much to detect automatically so i think this may be something i have to do manually. Thanks ---

If you have the Discnumber tag filled you can use this: C:\Music\\%artist%\\%album%[- %year%]\$ifgreater($num(%discnumber%,1),2,$num(%discnumber%,1)\,)$num(%track%,2) - %title% For the second question: It's not possible to compare different files within the scripting. ---

Hi dano - thanks for the response. That dosn't quite achieve what i was looking for. I mean if there are 1 or 2 discs all tracks are put here: artist - album - tracks however if there are 3 or more discs put each track for each disc in a corresponding folder: artist - album - disc1 folder, disc2 folder, disc3 folder (each folder containing corresponding tracks) After using this on a 4 disc album i got this: Artist - album - tracks (for disc 1 and 2) and 2 folders called 3 and 4 containing the tracks for disc 3 and 4. Sorry if i wasnt clear. ---

You are right. I overlooked that we need to check the total disc count. So the question is do you have that info saved in a tag as well? Like Discnumber = 1/ **4**? ---

yep, albums that are just 1 disc i have no field for discnumber. All albums that that contain more than 1 disc have discnumber field saved correctly ---

Now a new disc folder is only created if there's a discnumber tag like 1/4 with at least 3 total discs: C:\Music\\%artist%\\%album%[- %year%]\$ifgreater($regexp(%discnumber%,'^\d+(/|$)',),2,$num(%discnumber%,1)\,)$num(%track%,2) - %title% ---

Hi, i was wondering if you could help me make a small change to this: C:\Music\%artist%\%album%[- %year%]$ifgreater($regexp(%discnumber%,'^\d+(/|$)',),2,$num(%discnumber%,1),)$num(%track%,2) - %title% In the \%labum% section is it possible to say if you find a ":"(without quote marks) replace with a " - " Just because windows wont allow for ":" so when the folder is created it would be better to replace it with a " - " Is this possible? ---

> [@fers](#): > > ... Is this possible? have a look at the $validate function. if you want to be sure you could modify the mask like this: C:\Music$validate(%artist%\%album%[- %year%]$ifgreater($regexp(%discnumber%,'^\d+(/|$)',),2,$num(%discnumber%,1),)$num(%track%,2) - %title%) ---

Ah nice, will this affect filenames etc, or just where symbols are invalid like folder names? ---

I don't understand. No, it does not affect existing filenames. And everything else will be revealed to you by having a glance at the online help. ---
