Small helpful thing, wanted to share. I often have my Windows 10 Explorer Preview Pane on, and it’d be nice to preview AL Code in it as text.  So, here’s how to enable that.

Pop open regedit.   Create a new key for “.al” in HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.

Change the new (Default) text to something descriptive like “AL File”.

Add a new StringValue called “PerceivedType” and set the value to “text”.
