How do you define an Image when you search?
For example, when I search and use'kind:=picture', I get a my autocad .dwg files in my search results as well as .jpg, .gif etc
So, how do you tell Windows, which file extensions constitute a picture (or any other file extension for that matter)?
Thanks

I have never succeeded in changing a file's Kind.
But you could search for something like this example
Code:*.jpg OR *.png

Hi, 'kind' relates to 'perceived type' held in the registry against certain file types.
What is the purpose of "Perceived Types" in Windows 7-10? - Super User

If you wish to search for a selection of file types you could do this:
type:jpg OR type:bmp
and append your particular search criteria.
Or you might prefer to exclude just one file type e.g.
s* NOT type:dwg
would find all files begining s excluding dwg files.
Thanks guys, very interesting read.
You might have thought that Microsoft would have built in a way to change the perceived types as it is not unreasonable for new extensions to come in to existence which would fall in to different categories especially when you are using for a specialist purpose but then again under these circumstances I guess you'd be better off with a document management system rather than Windows!!
Applications register file types [see the second of dalchina's links]. I do not know how they do it but it is not merely by adding to the list in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\KindMap
because that's how I tried to do it and it had no effect on my search results.
- I renamed a [picture] file with a file extension .abc and added that extension to that Registry list.
- I rebooted and repeated aKind:picture search I had done beforehand. Only my original files were identified. The faked .abc file was not.

A bit more:

There seems a link to the PerceivedType value present for some common file types e.g.
You can use this free program to readily see which file types are associated with a given perceived type:
May be due to indexed information which needs to be refreshed perhaps?

Yep, got it.
It's due to indexed information.
I used FileTypesMan to change PercievedType to 'Document' and then went to Folder properties --> Advanced --> untick index --> apply changes, back to Advanced --> tick the index files option again which forces re-index of that folder only rather than a re-index and now the .dwg shows up as a 'Document' and not a 'Picture'.
Thanks for your help guys
Did altering its file association, as you did, also alter its entry in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\KindMap
?

Changing in the registry had no effect. It was not until I changed using FileTypesMan did work.
Must be something int he background at play here...
Yes, changing file associations sets more Registry entries than the file association ones.
I've found this discussion interesting, thanks.
