Open file by extension only with batch file

I've been looking for the correct code for my batch file to start a program and open a file by extension only. I've been searching and all I can find is opening a file by filename only, without extension. I would like to do it the other way around. I've tried multiple 

start "C:\program files\folder\program name.exe" d:\folder\filename.extension

I've found some answers for other programs and tried them but they didn't work. I've tried to replace filename by * but it didn't work as well.

The reason I'm asking is becasue the filename will change every buildnumber but the extension is unique in that folder. Hope you can help me out. Thanks

You can do as follows 

rem ** go to the folder 
CD d:\folder

rem ** find all the filenames with required extension using a for-loop

FOR /F "tokens=1 delims=" %%A in ('DIR /b *.extension') do (
    rem ** Added some delay before start as per OP comments
    timeout 5
    rem ** use start command
    start "C:\program files\folder\program name.exe" %%A
)

Edit : Added Timeout for some delay before start as per OP's comment

You should be able to do:

start "" filename.extension

The double double quotes provide the name for the window for some weird, illogical, Microsoft-y reason.
