[Closed] Get/Set external file properties with maxscript?

there is no way to get it with maxscript only. there are some free DLLs which give access to file proprties (some of them are open source). using .net you technically can get this data. try to search on this forum, i posted some links.

yes. it’s Calum McLellan StructuredStorage. I think it’s one of the best things about this matter. I’m using my own but his one is much more powerful. Unfortunately I can’t share my DLL but my experiments with Calum’s might be helpful:

global StructuredStorage = dotnet.loadassembly @"C:\Tools\StructuredStorage\64\CalumMcLellan.Struct  uredStorage.dll" 
-- read properties
(
	file = @"C:\Temp\attr_test01.max"
	PropertySets = dotnetobject "CalumMcLellan.StructuredStorage.PropertySets" file on -- ON is for read only
	member = dotnetclass "CalumMcLellan.StructuredStorage.PropertySetIds"
	format "Summary:
"
	if PropertySets.Contains member.SummaryInformation do
	(
		SummaryInfoIds = dotnetclass "CalumMcLellan.StructuredStorage.SummaryInfoIds"
		pp = PropertySets.item[member.SummaryInformation]
		
		title = pp.item[SummaryInfoIds.Title]
		format "	%: %
" title.name title.value
		subject = pp.item[SummaryInfoIds.Subject]
		format "	%: %
" subject.name subject.value
		author = pp.item[SummaryInfoIds.Author]
		format "	%: %
" author.name author.value
	)
	format "Custom:
"
	if PropertySets.Contains member.UserDefinedProperties do
	(
		pp = PropertySets.item[member.UserDefinedProperties]
		enum = pp.GetEnumerator()
		enum.MoveNext()
		while enum.current != undefined do
		(
			format "	%: %
" enum.current.name enum.current.value
			enum.MoveNext()
		)
		enum.Dispose()
	)
	PropertySets.Dispose()
)
-- write properties
(
	file = @"C:\Temp\attr_test.max"
	PropertySets = dotnetobject "CalumMcLellan.StructuredStorage.PropertySets" file off -- OFF is not read only
	member = dotnetclass "CalumMcLellan.StructuredStorage.PropertySetIds"
	format "Summary:
"
	if PropertySets.Contains member.SummaryInformation do
	(
		SummaryInfoIds = dotnetclass "CalumMcLellan.StructuredStorage.SummaryInfoIds"
		pp = PropertySets.item[member.SummaryInformation]
		
		title = pp.item[SummaryInfoIds.Title]
		title.value = "changed"
		format "	%: %
" title.name title.value
	)
	PropertySets.Dispose()
)

best,
