Zip - unzip problem....

[Lindon]

So I have 6 zip files:

SampleFiles01.zip
SampleFiles02.zip
SampleFiles03.zip
SampleFiles04.zip
SampleFiles05.zip
SampleFiles06.zip

They are all about 2.2GB in size....

• my app finds them fine and unzips the first one correctly, it then goes on to unzip the following ones very quickly - and instead of placing the correct data into each of the ch1 files it creates "little" ch1 files (each of them 32 KB in size)

What am I doing wrong?

heres my unzip code:

function processZipListItem()
{
	zipFileCollection[zipListPosition] = zipFolder.getChildFile(zipDestinations[zipListPosition].File);
	writeLog("Extracting:" + zipDestinations[zipListPosition].File + " to:" + zipDestinations[zipListPosition].Destination);

	//zipFileTargetDirectories[zipListPosition] = 
	zipFileCollection[zipListPosition].extractZipFile(zipDestinations[zipListPosition].Destination, true, function(zipState){
		if(zipState.Status == 2)
		{
			if(zipState.Error != "")
			{
				Console.print("Zip extraction problem:" + zipState.Error);
				writeLog("Zip extraction problem:" + zipState.Error);
				writeLog(" ");
				writeLog(" ");
				unzipNotificationText1.set("text", "Unzipping problem encountered - see below...");
				if (OS == WINDOWS)
				{
					unzipNotificationText2.set("text", "Please make sure you are running the installer as Admin on Windows...");
					unzipNotificationText3.set("text", "(right click on the installer and select \"Run as Administrator\")");
				}else{
					unzipNotificationText2.set("text", "");
					unzipNotificationText3.set("text", "");
				}
				unzipNotificationPanel.showControl(true);
			}else{
				// we are complete successfully
				zipListPosition++;
				if(zipListPosition < zipDestinations.length)
				{
					// we have more to process...
					processZipListItem();
					return;
				}else{
					writeLog("Zip extraction complete:");
					zipCompletion();
				}
			}
		}
		
	});	

}

@Lindon I'm not 100% sure but I'd try to do it without the recursion.

This is how I'm doing it - https://github.com/davidhealey/HiseDownloadManagerToolkit/blob/master/Expansions.js#L207

@d-healey ok will do thanks - tho I'm beginning to think its the size of the zips themselves as the first (1.9GB) and the last (890MB) both extracted correctly...

[d.healey]

@Lindon Oh yeah, if they're over 2GB you might have issues. I've never tried with files that large.

Ok so this WAS the issue - redoing the zips as 1.5GB each and they unzip correctly....
