Export group's name to excel (xlsm) or notepad .txt or .doc etc

...

I don't know abouth that limitation because never before print that count. Probabli is some memory problem. This works (1 million lines *.txt file)

fn printAllGroups txtFile = 
(
	array = for i in 1 to 1e6 collect i as string ; gc light:on
	(dotnetclass "System.IO.File").WriteAllLines txtFile array
)
printAllGroups @"c:\temp\numbers.txt"

.

Branko, for some reason(unknown to me) WriteAllLines have one dissadvantage - it can't print more than 80 000 lines. I think that was the correct number, or it is close to the correct.

In the past I created a script that prints about 300 000 lines in a single file. Then I discover that WriteAllLines can't help in such a situation.

Try this fn. Also change filename path

fn printAllGroups txtFile = 
(
	helper = for node in helpers where isGroupHead node collect node.name
	if helper.count == 0 then messageBox "No Groups in the scene!" title:"INFO" beep:off else
	(
		(dotnetclass "System.IO.File").WriteAllLines txtFile helper ; free helper
	)
)
printAllGroups @"c:\temp\SceneGroups.txt"
