All source files in the Piwik demo project have filename en.json.


  1. The Search dropdown box provides some prepared search functions.



    If you would select Resx-files, then after the selection, the Search box will show \.resx$.



    This is a Regular Expression that selects all files that end with .resx. The $ indicates the end-of-string.

  2. Enter the regular expression in the Search field.

    In the case of demo application Piwik, we want to select all files that have name en.json.
