MAXScript: getMaxFileVersionData always returns "undefined"!

[Phil_Morgan]

The getMaxFileVersionData command always returns "undefined". Why?
I tried to save a file from different versions 2020-2025, but when using the command getMaxFileVersionData "C:\\my_file.max" I always get "undefined", although the documentation says that I should get an array with the original version of the file and the version in which it was saved (https://help.autodesk.com/view/MAXDEV/2024/ENU/?guid=GUID-F693FDB5-1B1B-4A4D-9C48-ECF91272FD88). How to make the command getMaxFileVersionData work correctly?

link an example file... we will check

Most likely, the file you are trying to open does not exist in the specified path, or the path itself is specified with incorrect syntax.

It's just an empty file. The file exists and the path to it is specified exactly.

Here is this file (3dsmax 2024).
I tried running this command both in the MXS Listener window and from the script editor (Cntrl+E) - the result is the same: undefined

[denisT.MaxDoctor · Accepted solution]

the wrong syntax as I expected...

it must be 

@"J:\TEST\test.max" 
-- or 
"J:\\TEST\\test.max" 
-- or 
"J:/Test/test.max"

"\t" is a tab char

Exactly! This is my mistake 😞
Thank you very much, Denis!
