Hi all.

I'm going to do a command to write a file, is that:

bm01 = rendermap (mix()) size:[100,100]
bm01.filename = "c:\\temp\\tem_01.jpg"
save bm01
close bm01

But after write the file i want to check if the file exist, how can i do that?

Thanks.

This is directly taken from the MaxScript User Reference:

fn existFile fname = (getfiles fname).count != 0

This Function test if the specified file exists.

This is a left over from the Max 2.0 MAXScript Reference ;)
It still has one advantage over doesFileExist() - at allows for file name wildcard patterns, so you can say

existFile "c:\\temp\\test*.tga"

and it will return true if ANY file with that pattern exists, like c:\temp\test.tga, c:\temp\test0001.tga etc. I added a note to the MAXScript 2010 Reference regarding this to avoid confusion and cross-linked to doesFileExist() so you cannot miss it.
