Backing up files before Android update

As of Nov 1 2021, all new apps and updates on the Google Play store must update to API30. A significant impact of this is that it changes the permissions apps have for opening and saving files.


Note: These changes will apply only to devices using Android 11 or later. Devices with earlier versions of Android, or on Chrome OS, will not see a change in how files are opened and stored.

For Sketchbook, this means the app will no longer be able to store files in the Autodesk > SketchBook3 folder that it has been using for years. All these files must be migrated to a new location.

We have developed a migration workflow that you will see on first launch after the update that will copy your files to the new location. The time this process will take may vary depending on your device, and the size of your Sketchbook Gallery.

We are rigorously testing this process, but it is impossible to emulate every possible set of events. The safest situation is for you to please back up your data.

How to back up your art files on Android

  1. Navigate to Files or Internal Storage (this may be called something different depending on your device manufacturer)
  2. Find the folder Autodesk
  3. Click in to the folder SketchBook3
  4. In this folder you will see a number of files with the extension .tiff. These are your Sketchbook art files.
  5. Copy these files (do not delete, remove, or rename them) to a second location in the cloud or on an SD card.

If you ever need to restore a backup, you can copy these files back to your device and run the Recover Images tool in Sketchbook.
