Hi
I want to have extensions of files on parent directory if the files are not MP3. Is That Possible??
Here is an example :
1.
File ext: mp3
New File name: %albumartist% - %album% %year%\%artist% - %album% - $num(%track%,2).%title%
1.
File ext: flac
New File name: %albumartist% - %album% (FLAC) %year%\%artist% - %album% - $num(%track%,2).%title%

You could apply a filter and then rename the files accordingly ...
%\_tag% HAS FLAC
filters those with Flac tag ...

Thanks, but that is not what I want, I want sth to saves me from everytime editing the pattern & having a huge hstory in it. what I meant was using sth like:
$if(NOT %\_extension% IS mp3,,"("%\_extension%")")
but this doesn't seem to work... am I missing something??

an example mask would be:
%artist% \_$if($eql(%\_tag%,'Flac'),%\_tag%,) %album% \_ $num(%track%,3) \_ %title%
for Flac files. The preview should show the result for the first selected file.

Thanks So much..... I edited the if function to meet my needs: 😃
$if($eql(%\_extension%,'Mp3'),,"("$upper(%\_extension%)")")

Two proposals ...
**%ALBUMARTIST%' - '%ALBUM%$if($eql(%\_tag%,'FLAC'),' FLAC ',' ')%YEAR%'\'%ARTIST%' - '%ALBUM%' - '$num(%TRACK%,2)'.'%TITLE%****%ALBUMARTIST%' - '%ALBUM%$if($neql($upper(%\_extension%),'MP3'),' '$upper(%\_extension%)' ',' ')%YEAR%'\'%ARTIST%' - '%ALBUM%' - '$num(%TRACK%,2)'.'%TITLE%**
