simple batch command to copy few files

[miozeriux]

Hello, I don't have any experience in programming and I'm trying to create a simple .bat file for my work which I would put in a directory I want, and it would copy all the files with certain extensions + one more file (which always has the same name) from the directory I put the .bat file in, to a newly created folder in the same directory (or on the desktop doesn't really matter).

I've spent few hours trying to learn batch commands I need and writing this script but without much luck. As i understand, I need to use Xcopy command for copying, then %~dp0 to select the current directory (where .bat file is in) then list the extensions I need to be copied which are ._cad.stl *.constructionInfo *.dentalProject * preview.png (this one is optional i could do without it if it's more complicated) and then use mkdir command to create a new directory, but i'm not sure how to make it work and put it all together, any help would be extremely appreciated, thanks big time guys ...
