Hi guys, I am trying with no results to find a way to lowercase the parent folders of albums. Any advice? You may take a look at the action I wrote, don't know what to add.. Thanks! ![](http://i.imgur.com/YFwwy4j.png) ---

Thanks for your reply, but I mean "%artist% - (%year%) %album%", I tried to use the $lower() function and "Case conversion: \_DIRECTORY" with no results. ---

Why dont you use the $lower() function in the middle of the definition of the filename? This would save you one action. Also I think that in Windows you have to actually rename a folder by adding a dummy string and convert it to lower case at the same time - otherwise Windows does not modify the case. You then need a second action to remove the dummy string from the folder again. ---

Hi, well, I already tried, but in Win 10 the lower function does not work (see screenshot), it just creates a new folder (probably I am doing something wrong, sorry I am a noob). In the end I decided to use another app (just to rename the folders) since I really did not find out a solution. Thanks anyway! ---

I just tried more or less you string: c:\users\public\Podcasts'['library']'$lower(%artist% - (%year%)%album%)$num(%track%,2) %title% This gives this result: "c:\users\public\Podcasts[library]\1live comedy - (2015)1live comedy sammler\02 TV Total" which looks just like that what you described ... So perhaps you check the syntax again ... ---

I checked again, and now $lower(%artist% - (%year%)%album%) works, like you said I probably made a syntax error in my fist attempts, thanks a million ![^_^](https://community.mp3tag.de/uploads/default/original/1X/15b21e4a9fd37d565d77674de6a426ea5c1c9673.gif "^\_^") ! ---
