Save file size too big ?

[micheus]

It's working fine now, though it always gets non-responsive when I save, but luckily only for a few seconds. More often the erl.exe still crashes when I load this one specific project.

yeah, erl.exe can hang for a little if it's handling a lot of data in that moment.

I'm using the 64 bit version, windows 7.

This version has less problem with the memory limit of 32bits one.
So, just to know, how many vertices have your project?
Are your objects textured too? If so, it's a good idea have the images made external since the internal option can use a lot of memory and make the project file huge.
