Designers sometimes need to test how a file renders in different Photoshop builds. Portable versions can be kept in separate folders (2020, 2021, 2022 v23.01) without conflicts.

While version 23.0.1 introduced these innovative tools, user feedback at the time was mixed regarding stability:

The Adobe Photoshop 2022 version 23.01 portable is a self-contained version of the software that can be run directly from a USB drive or any other portable storage device. This version does not require installation and can be used on any computer without leaving any files or settings behind.
