I'm trying to write a .wav file to the default folder using the message connected to [buffer~]. I get this message in the console:

jsoundfile_writefloats: could not create output stream. check permissions of output directory.

If I specify a folder (as in full file path C://Users//etc), it works fine: but this patch is meant to be transferrable rather than used just on my computer. The saving and reading from the default folder works fine with [coll] (.txt) and [lcd] (.png). The file name doesn't have any special characters apart from letters so it's not a string thing (that sometimes confuses Max). Reading a .wav file from the disk into [buffer~] is also fine. The only thing I don't know how to find is what the "output directory" is, but if it's the same place as the .txt and .png files were saved into, it's right next to the patch file itself. The reason I need this to work is because I have three separate patchers which happen one after another but need to pass information forward.

I'm submitting this work for a university assessment in a few days and this is the silliest problem, would appreciate any help!

I am using Max 7 on Windows 10. I've tried running it as administrator to see if that gets around the permissions bit but it doesn't affect anything.

you could use something like the following to create a full path to where your patcher is, to use for saving the file.

As for the permissions, does the file already exists? Maybe another objects read it and prevents from writing?

Hi, I was doing as Nikolas suggested, but so far I haven't had this problem in Max8.2 if I send a 'writewave {filename.wav}' message rather than a 'write {filename.wav}' message. If I use a 'write' message rather than a 'writewave' message, I still get random permission errors about half the time.
