Haven't mention where do I need paste filesync.mapping

Is that in settings.json file? or a new file?

It is in settings.json. You can get to it from the UI too:

Example:

You meant "under the project folder .vscode -> settings.json" right. I did that it didn't work.
vs code version 1.45.1 -> when I activate File Sync I am always getting No mapping found for "souce_path" all the time. I checked couple of things to work this out but couldn’t ended with solution.

So, I have created a new Extension called RunCommandOnSave <- User has a privilege to run any command he likes on file save.

No, this is a VSCode (User) setting not a project setting. You should be able to bring up the User settings.json with ctrl + shift + p and typing settings.

It might be an idea to support project settings in the future.

Hi, by putting the the mapping in the global settings (Windows %APPDATA%\Code\User\settings.json) does worked; but may I know am I able to put the settings in my project's folder itself? I tried to create a .vscode folder inside my project folder and created and settings.json inside it. But somehow it doesn't read the settings inside my project folder.

I read it from here to do it in folder:
