I didn’t include any code as I didn’t want to just post other people’s code (I’ve just been trying code snippets directly from the forums to see if I can get anything to work), however here are the two topics I have referenced and directly tried:

Can you look at the following code and tell me what I need to change. When I run it I get the folder picker dialog, select folder, but no file gets saved. Debugger doesn’t show any errors. const persistentFolder = await fs.getFolder(); const newFile = await persistentFolder.createFile("newfile.tif", {overwrite: true}); const saveFile = await …

I correctly get a dialog to select the folder, select eg. the desktop or c: drive, after that all I get is “createFile is not a function”. Is getFolder failing for some reason or has something changed about create…

I’ve taken the code as is and modified it with any additions in the replies that supposedly make it work. The code was put in an async function being called on the click event of a button.

From my understanding after doing more research, ExecuteAsModal is required in API 2, though I’ve found the documentation on this a bit hard to follow.

As a place to start though, here’s a sample I’ve put together that doesn’t work based on output from Alchemist:

```auto
async function OnExportButtonClick()
{
    const fs = require("uxp").storage.localFileSystem;
    const persistentFolder = await fs.getFolder();
    const newFile = await persistentFolder.createFile("texture.png", { overwrite: true });
    const saveFile = await fs.createSessionToken(newFile);

    const batchPlay = require("photoshop").action.batchPlay;
    const result = await batchPlay(
        [
           {
              _obj: "save",
              as: {
                 _obj: "fnord SuperPNG",
                 $pngC: 9,
                 $pngF: 248,
                 $pngS: 0,
                 $pngQ: false,
                 $pngA: {
                    _enum: "$alfT",
                    _value: "$alfC"
                 },
                 $pngX: false,
                 $pngI: false,
                 $pngM: true
              },
              in: {
                 _path: saveFile,
                 _kind: "local"
              },
              documentID: 219,
              copy: true,
              lowerCase: true,
              alphaChannels: false,
              saveStage: {
                 _enum: "saveStageType",
                 _value: "saveBegin"
              },
              _options: {
                 dialogOptions: "dontDisplay"
              }
           }
        ],{
           synchronousExecution: false,
           modalBehavior: "fail"
        });
}

```
