You can use File.applicationDirectory and put the 7za.exe in your project
folder. I placed it in /native_bin/win/7za.exe. Make sure the file has
"execute" permissions (right-click for properties of the file in Flash
Builder).
I have defined it as NativeProgramsSettings.UNZIP =
File.applicationDirectory.resolvePath("native_bin/win/7za.exe"); for
Windows and NativeProgramsSettings.UNZIP =
File.applicationDirectory.resolvePath("native_bin/mac/7za"); for Mac
(depending on Capabilities.OS)
Then for unzipping (I don't use zip functionality in my app) it is as
follows:
private function unzipNative(zipFile:File):void{
this.dispatchEvent(new Event("indicatorShowRequest"));
var targetDir:File = File.applicationStorageDirectory.resolvePath("unzipped"
);
targetDir.createDirectory();
targetDir = targetDir.resolvePath("unzip_" + new Date().time + "_" +
Math.round(Math.random()*10000));
targetDir.createDirectory();
tempDirectoryForZip = targetDir;
var npInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo;
npInfo.executable = NativeProgramsSettings.UNZIP;
var args:Vector.<String> = new Vector.<String>;
args.push("x");
args.push(zipFile.nativePath);
args.push("-r");
args.push("-o" + targetDir.nativePath);
npInfo.arguments = args;
var np:NativeProcess = new NativeProcess;
np.addEventListener(NativeProcessExitEvent.EXIT, npUnzipExitHandler);
np.start(npInfo);
}
For zip you need to have different arguments of course. You can check by
googling "7za command line".
Hope it works for you
