by the way does there is a way to save to subdirectory ? what is the syntax ? write dir/file ?

Strange error indeed. It seems to work better if you use write toto.maxpresets and read toto.

If you want to save in a subdirectory, you need the full path using Max' path syntax. Check objects like absolutepath to learn this syntax and combine to construct them.

Don't forget to use tosymbol when manipulating symbols which can contain spaces (like a path or a file name), or will have some bad surprises.

Good luck!

thanks for the subdirectories but I get the same error with write toto.maxpresets

Does this not work for you?

-Ben

it works I went to my problematic patches it seems naming .maxpresets is the only way the error message is wrong and the documentation and example incomplete.

all these small glitches cost hours

Thanks Ben

you need a file extension but it hasn't to be .maxpreset
