After double-clicking on the unknown file icon, the system should open it in the default software that supports it. If this does not happen, download and install the 7-Zip software and then manually associate the file with it.
If there is no 7-Zip or similar software in the system that supports files with the 010 extension, you must first download and install it. Below you will find a list of the most-used applications that work with 010. After going to the subpage of the program you will find a link to the developer's website, where you can safely download the software installer.
