when I query the size of a polybuffer~ object (getsize msg), I get a number of bytes which is more than double the size of the folder I load.

If I need to load a lot of files, should I consider to have more than 2 times the amount of available RAM?

If you're files are in 16 bits, yes this is normal. 

 load sound files and store them as 32 bits float values, it'll take twice the size of the 16 bits integer file that you have on disk.

I had a related question - does the length of any individual file/sample in the Polybuffer have any bearing on whether Max can handle it or not? I have 60 2-minute files loaded into 6 polybuffer objects (10 each), and I'm getting out of memory complaints. If it is simply a case of 'total memory' per buffer then no problem, I can just decrease the duration of all the files and that will reduce the overall memory size, but is there also any issue of 'memory per file' that might be causing it to choke?

2 minutes at 44100 Hz, is roughly 21 MB, 60 of those is 1.26 GB, so unless you run in 64 bits and have a lot of memory 10 times that is going to be too much :-(

Thanks Emmanuel. To be clear, the out of memory problem is occuring on dragging the folder into the polybuffer object, not during playback (I am not playing all files back simultaneously). After some editing down, I was able to get all files into the polybuffers and they run just fine. I'm running 64-bit with 8GB RAM so maybe that's enough.

I do have another question actually - is there a simple way to read name of the file currently selected out of polybuffer? Not the shortname reference, but the actual filename. Do I need to use a coll for this?
