For document-based workflows that utilize document types, a new data source type is also available to support folders as data sources. Google Drive is the first system supported, with the intention of adding more folder data source systems in the future.
Folders are fixed schema tables, where the attributes (table columns) are the properties of files (such as name, size, last modified at, etc.) and the entries (table rows) are the files themselves. In the AppSheet Automation Preview release, each folder should contain files of the same document type, although the files can vary in mime and extension type.
Note: Supported extensions in the Preview Release: .tiff, .gif, and .pdf. Folders containing mixed document types can be used for document viewing and upload inside applications, but can not be automatically extracted.
For the Preview Release, folder data sources can be either implicitly used as part of configuring document extraction, or explicitly used as data sources for building views to show documents in the application. For example, a "user manual view" in an application can explicitly use a Google Drive folder data source containing documents that can be viewed, updated, added, or deleted within an application.
