JavaScript - save file to folder in parent directory

[friendship.machine]

Hello everyone!

I managed to frankenstein together a javascript I found online to save out a JPG and PNG from a PSD to the parent directory and folder inside the parent directory.  After a couple of nights of troubleshooting, the script below is doing MOSTLY what I need.  From the working file (the PSD directory), I'm able to save out a JPG to the parent directory but I can't figure out the magic combination to send the PNG to the PARENT->PNG folder.  Any help is appreciated!

MY DIRECTORY + FILE SETUP:

• PARENT (holds the PSD folder, PNG folder and JPG files)
  • PSD (these are my _working files)
  • PNG

THE SCRIPT:

// reference open doc
var doc = app.activeDocument;

// define parent directory
var parentF = new Folder(doc.path.parent);

// set save options for JPG
var jpg = new ExportOptionsSaveForWeb();

jpg.interlaced = false;
jpg.quality = 100;
jpg.includeProfile = false;
jpg.format = SaveDocumentType.JPEG; // Document Type

// save png file in parent directory of open doc
activeDocument.exportDocument((doc.path.parent), ExportType.SAVEFORWEB, jpg);

//set save options for PNG
var png = new ExportOptionsSaveForWeb();

png.PNG8 = false;
png.transparency = true;
png.interlaced = false;
png.quality = 100;
png.includeProfile = false;
png.format = SaveDocumentType.PNG; // Document Type

// save png file in PNG folder in parent directory

activeDocument.exportDocument((doc.path.parent + '/PNG'), ExportType.SAVEFORWEB, png);

Document.exportDocument (exportIn: File , exportAs: ExportType , options: ExportOptions )  

First argument must be File (full path with filename). Folder to export this file must be created before.

var png = new ExportOptionsSaveForWeb();

png.PNG8 = false;
png.transparency = true;
png.interlaced = false;
png.quality = 100;
png.includeProfile = false;
png.format = SaveDocumentType.PNG; 

// save png file in PNG folder in parent directory
var exportFolder = Folder ((app.activeDocument.path.parent) + "/PNG")
if (!exportFolder.exists) exportFolder.create ()
app.activeDocument.exportDocument (File(exportFolder + "/" + app.activeDocument.name + ".png"),ExportType.SAVEFORWEB, png )

This is perfect!  Thank you very much, Dmitry!

Hi Dmitry I like your script, however, one thing struck me as potentially requiring modification...

I'd add a filename variable to strip the source filename extension so that the result is not a double extension such as .psd.png etc.

var baseName = app.activeDocument.name.split('.')[0];

//...

app.activeDocument.exportDocument (File(exportFolder + "/" + baseName + ".png"),ExportType.SAVEFORWEB, png )

Great catch, Stephen.  I noticed one of the files had the psd.png and your update corrected it.  Thanks so much!

download and install the plug-in  Image Processor Pro.... It should be easy to do what you want to do using it.

Ah nice.  I'll look into it.  Thanks JJ!
