create zip file via JSX

[Charbel22815960bybb]

hello everyone!

I am planning to create a zip file containing a list of images generated from a PSD using "JSX"
is there a way to zip all exported images via Javascript

Thanks

Play with methods for decompression and then try to do what you need perhaps yourself: Unzip a file

Thanks for the reply,
This put me on the right track

You could end up with a HUGE zip file. It is possible, I have a Bridge script in development that zips a set of files via command line.

Are you on Windows or Mac?

Thanks for the reply

I will have to use both it depends on the user machine
I am trying to execute this on a windows machine

var cmd = 'powershell -Command "Compress-Archive -Path %cd%\application\slices* -DestinationPath %cd%\application\zip2.zip"';
app.system(cmd); 

I don't know if it works or I can run a batch that does the job for me

any advice?

I haven't written the Mac function yet, ditto is the best approach but there are some issues with it, I may have to use OSAScript/AppleScript and the System Archive Utility instead. But this works for Windows at least. Apache-licensed if you feel like forking it.

Thanks for the reply,

what I actually did was I created a .bat file from jsx and and wrote the code inside of it that zips all the assets delete the folder andthe batch file itself.

I think this can solve my issue for the time being, this is the code hopefully it can be helpful to anyone

function zipFiles(){
    var fullPath = activeDocument.path + "/application/compress.bat";
    var file = new File(fullPath);

    var batchcontent = 'powershell -Command "Compress-Archive -Path %cd%\\slices\\* -DestinationPath %cd%\\archive.zip" \n powershell Remove-Item "%cd%\\slices" \n Del compress.bat'

    file.open('w');
    file.write(
        batchcontent
    );
    file.close();
}

zipFiles()

So now you need the same for macOS 😛

[Lumigraphics]

zip and ditto work similarly but not exactly on macOS, ditto will work on a folder but not scattered individual files. Dude's code above zips a folder while mine zips a set of selected files regardless of location.

[m23405306ct5g]

will this also work on windows?

[Kukurykus]

Confirm that's a joke, not a SpamBot activity otherwise you'll get banned 😉

I asked to be sure as we have lately flood of bots over here 😉
