filename autocompletion dependances?

[caps_buster]

I wonder who can tell me, on what is dependent the "filename autocompletion". I maybe name it wrong, but what I mean is that when for example uploading image on web pictures hosting, then before windows reinstall I only need to enter the image NAME, w/o the ".jpg" and it worked fine and the filename it completed by the comdlg32 dll that handle the open/save file requests.

Now I probably overoptimized in Autoruns and disabled something that should not be disabled, I quess. Anyone have some hints about what can be re-enabled to get this "extension of filename automcompletion" working again?

Thanks for suggestions

What is Indexing Service?

It's a wild guess, but I did notice some programs would accept it without specifying a file extension, and some wouldn't. Office 2003 was really annoying, opening files by keyboard always necessitated the extension.

Indexing service?

I always disable it, because I do believe that it is used to index the NTFS HDD partitions to speed up searching, or so they say...

And - granted. I start it, and no change in behaviour. You say this might depend on application? I'm affraid that I updated Firefox from 3.0.11 to 3.0.13 ...

Did fresh install to test recently and no change in behaviour Help?
