File Exporter Windows Path Issue

[bluerose73]

Hello developers, thanks for your great work! This extension is super handy when I want to track coding behaviors at key-stroke level of detail.

The file exporter cannot handle Windows path correctly. Below is the error message from the Developer Tools console.

I have created a PR to fix this issue.
