Is there any way to reset the default option as "Current File" in "Replace" of WebStorm?
You cannot.
The reason why I need it cause it'll be better for me to get a quick and entire view for the content I am searching.
You can see the same "entre view" using in-file replace:
There is an "Open in Find Tool Window" button in the search toolbar that will open ALL matches in a standard Find Results toolwindow (the same window that you get when you hit the "Open in Find Window" button in the bottom right of Find/Replace in Files). So ALL matches will be listed there;
the Preview area is also available (may need to enable it first -- there is a button for that). It also allows editing the file content right there.
