Have you checked that 'name' has content and points to a valid path?
I can't see anything obviously wrong, otherwise.

i tried it this way, too
nothing happens, no file created
i can´t see the mistake
could you give me a very little example for a plugin that saves a string to a file, plz ??

It works fine for me here:
AutoAlloc<BaseFile> bf; if (!bf->Open(presetdirectory,GE_WRITE,FILE_NODIALOG,GE_MOTOROLA)) return FALSE; -

ok, here is my code, i hope the variable "name" in the save-method is used correctly:

tag = tag->GetNext();
}
}
else MessageDialog(" - no object");

}
Bool RegisterSMD(void)
{
if(!RegisterSceneSaverPlugin(1111111,"SMDex",0, SMDFilter::Alloc, EXECUTION_RESULT_OK, 0, NULL)) return FALSE;

}if so, what´s wrong here ?
thanks a lot for your help!!! -

The rest of the code shouldn´t have an effect on the save operation. The save code is correct, not sure why it doesn´t work for you. I assume it has something to do with the SceneSaver hook. (however I cannot really judge it, as I haven´t used this hook yet).
Mikael probably knows what´s wrong here, so I suggest to wait for his support.
