For direct access to the proper tools for working with Android, you might wish to download the SDK developers tool kit, found here:
Developer Tools | Android Developers
Read the installation requirements, as there are more objects to download, such as Eclipse, and the proper selection for the OS level you use, such as 64-bit, or 32-bit build levels.
Copying .blur files requires caution though, you need to know what folder to use, since .blur is a system file, it must be stored properly and its intents pointing to the application it needs to support and run.
A good, and usable root browser is part of Rom Toolbox, a paid and free app on the play store.
You MUST be rooted to access the root browser menu though.
If you are not rooted, try the one click method by installing Framaroot, which can be found in the tech section of the forum, there are also other methods available, such as Z4Root.
Good luck with your restoration project!
