How to create a file extension association with the program in Windows

Assume that you have a program named "table-explorer.exe".
And you want to open all ".csv" and ".sas7bdat" files using  this program by default in Windows.

First you need to create a file extension association with the program via these commands:


reg add HKCU\SOFTWARE\Classes\.csv /d "table-explorer" /f
reg add HKCU\SOFTWARE\Classes\.sas7bdat /d "table-explorer" /f


And then register the application:


reg add HKCU\SOFTWARE\Classes\table-explorer\shell\open\command /d "\"C:\Path\to\table-explorer.exe\"" /f
