Set windows 10 default app via f

Target: Set default app for specific file type

For instance, I want to set deault app for rar to "7zip", but this cannot be done directly via windows settings, the "7zip" is not listed in the drop-box.

So we can also set the default app via command line.

1. Set default app for ".rar" to "7zip"
2. Set default app for ".xml" to "nodepad++"

Steps:

• Find where are the two applications exe files are located:
  • In the windows search menu, type "7zip", there is the "7zip file manager", right click - open file location: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\7-Zip
  • In the new folder, right click on the "7zip file manager", right - property - shortcut, and in my scenario, it shows D:\Applications\7-Zip\7zFM.exe
  • With the same steps, locate the notapad++: D:\Applications\NotePad++\notepad++.exe
• First we can check the current default applications:
  • ftype | findstr xmlfile: xmlfile="C:\Program Files\Internet Explorer\iexplore.exe" %1
  • Run cmd as admin, run command ftype xmlfile="D:\Applications\NotePad++\notepad++.exe" "%1"
    If it succeeds, the output is: xmlfile="D:\Applications\NotePad++\notepad++.exe" "%1"
  • Check again: ftype | findstr xmlfile: xmlfile="D:\Applications\NotePad++\notepad++.exe" "%1"
  • Run the same steps for ".rar": ftype rarfile="D:\Applications\7-Zip\7zFM.exe" "%1"
    Check output: rarfile="D:\Applications\7-Zip\7zFM.exe" "%1"

And it's done.
