I've succeeded to exclude bower components and node modules from my search results by choosing the folder -> mark directory as -> excluded, but I couldn't do the the same for my concat file (a file with all code of the js files of my project).
How can I exclude this file from my search results?
Edit | Find | Find in Path
supports scopes. You can create a new scope (Settings | Appearance & Behavior | Scopes
) with the generated file excluded and use this scope for searching. Or, place your generated file(s) into a separate folder and exclude it like you did for bower_components and node_modulesEdit: since 2017.2 you can exclude files by pattern - see https://www.jetbrains.com/help/webstorm/2017.2/directories.html, Exclude files
