[INVALID] No extension is included with the downloaded flash

[surferby]

I can clearly remember that last time when I used flashgot to download flash video from youtube it included the file extension - .flv. It also renamed the file collecting data of the link description. That is because the Renaming mask was set to *flattext**name*.*ext* .

Now I have the same setting. But it only renames file according to the description and not including file extension (.flv). I want the downloaded file to include extensions. It is so boring to rename all downloaded file to include extension.

Can any wise guy guess the problem's root?

Sorry. This post must be deleted. This problem is associated with DownThemAll not not flashgot. As, after collevting link flashgot sends that to DownThemAll, that made me confused.
