When saving maya, you can be undecided about format, .ma or .mb
Mb means, “Maya Binary” file format. When you saved your scene as .mb , Maya compiles your scene,
Ma means, “Maya ASCII” file format. When you saved your scene as .ma Maya writes your all scene and their settings into a text, that means you can edit this .ma file with a word processor program (like Wordpad, Notepad)
When saving huge and complex scenes, .ma file format can look like a bit slower, but it worths to work stablely for a little seconds.
So, always keep your save setting as Maya ASCII (.ma) format.
To do that,
In [File] menu, select the little box in the line of [Save Scene As…]
Change [File Type] to mayaAscii and check [Default File Extensions]
Apply, and close…
That’s all folks,
Keep in Fx,
