Accessing external files

The iOS / iPadOS file system is very different than the file system on other operating systems. Files are placed inside containers. These containers are owned by different apps. They are all visible from the Files app but other apps don’t have access to files owned by other ones. Instead, the system gives access to individual files or folders selected by the user to be edited with the desired app.

Current Directory

Scripts stored in the Pyto container can access scripts in the same directory. If access isn’t granted, a lock icon is displayed at the bottom of the code editor. Pressing this button shows a folder picker. You can change the current directory, or just select the folder containing the script. This will not work for third party cloud providers such as Google Drive or Dropbox because they don’t have a real file system.


The file_system module has APIs for importing files and directories at runtime.
