Finding my Android app's file output when running on a Chromebook

Question

I'm working on an app to capture information into files. It runs well on my three android phones. I can find the files on the phones. I'm trying to get it running on my Chromebook (Acer 514). I'm monitoring the log using: adb logcat debug

My problem is, I can't find my files on the Chromebook.

When I run my app and save a file, the log tells me the file is at:

`/data/user/0/com.appname.capture/files/`

and I can find the files using Device File Explorer (in Android Dev Studio) at:

`/data/data/com.appname.capture/files/`

When I explore the device over USB, this dir shows up but is empty:

`...\Internal storage\Android\data\com.appname.capture\files\`

#1) Is there a way to "see" the files over USB? #2) Where are the files on a Chromebook?

I'm using Kotlin in Android Development Studio (current).

I'm using val outPath = filesDir and then I add subdirs to create the output file name.

filesDir is from the java.io.File import, I think i remember seeing.

The files are there because I close the app and re-open it and it loads the files saved.

Thanks in advance.
