Save for web filename problems

Question

I'm using a script to export layers to PNGs - but the filenames are getting screwed up.
Here's the export function:
function saveForWebPNG(name){
var docName = activeDocument.name;
docName = docName.slice(0,-4);
toWhere = new File(fullPath+"/"+docName+name+".png");
var opts = new ExportOptionsSaveForWeb();
opts.format = SaveDocumentType.PNG;
opts.PNG8 = false;
opts.transparency = true;
opts.interlaced = false;
opts.quality = 100;
activeDocument.exportDocument(toWhere, ExportType.SAVEFORWEB, opts);
I end up with things like this:
_generic_filter_failed_disabl#0
when it should be:
_generic_filter_failed_disabled.png
I have a feeling this might be to do with the settings trying to limit it to 32 characters (so they're unix compatible) - but if I change the settings in the Save for web dialog it makes no difference.
TIA,
James

> I have a feeling this might be to do with the settings trying to limit it to 32 characters
Yep. It's a hard limit on either the Mac or XP. You may be able to create
filenames with more than 32 characters, but only the first 32 are significant.
Back in the earlier MS-DOS days it was far worse.
>(so they're unix compatible)
Not a unix problem. You're filenames can be incredibly long on unix.

I really don't know what that setting controls. I thought it was more like the
character set or encoding of the filenames. Let me know if you figure it out.
