I also tried to do a local test, what I did is : create a local zip file, for example zip a music.map file to musicmp3.zip. I then use
zip musicmp3.zip --out splitArchive.zip -s 3m
Then I ll get files like: splitArchive.z01 // Zip archive splitArchive.z02 // for some reason mac shows it as ` Document` splitArchive.z03 // Showed as Document splitArchive.zip // Zip archive, but the name suffix is not .z04, but a .zip I use above to do a local test but the output unzipped file resultFileName.mp3 is zero bytes. I don't know it is because my code is wrong, or because my file type is not properly created. Can anyone give me some hints? I have stuck in this question for almost a week :( Thanks!!
