Update

After I posted it @0gtweet provided a feedback which I used to update the post. Thanks!

Old Post

This is just a blurb about a MSOHTMED cmd line arg I have not seen documented previously. Not sure if it can be used for anything special, but documenting it for the sake of it anyway.

MSOHTMED.EXE /oN <file>

will open <file> with a following program chosen depending on a value of N:

• 0 – Word
• 1 – Excel
• 2 – PowerPoint
• 3 – Access
• 4 – Sharepoint Designer
• 5 – Publisher
• 6 – Project
• 7 – Visio
• 8 – OneNote
• 9 – ForeFront (not confirmed!)

If a target app is not installed, the file will be opened by Word.
