Group Name = Render Output name

.

The script like this can be wrrtiten for 5 minutes or less. The problem is how the scrip to know this part: "C:/"
As you know Render Output must be a "path to folder" + "name of the file". The name of the file will be the name of the selected group. But how the script to know the path to the folder where the file to be saved?
If all images have to be saved to C:\ then use this:\

(
	function FindTopMostGroupHead obj = if isgroupMember obj do
	(
		while obj != undefined and (not isGroupHead obj or isGroupMember obj) do
			(obj = obj.parent)
		obj
	)
 
	selObjsArr = selection as array
 
	grpHead = FindTopMostGroupHead selObjsArr[1]
 
	rendSaveFile = true
	rendOutputFilename = "C:\\" + grpHead.name + ".jpg"
)
