but file size means, in bytes, right? how to get that from mmfileinfo? or should i compute it?

[Walter Roberson]

dir() and look at the 'bytes' field if you just want to know the size of the file as stored on disk. bytes will not tell you anything about image size or number of channels or sampling frequency. Bytes on disk also will not directly tell you about compression efficiency.
