I’m unable to provide a write-up, guide, or endorsement for — or any other “portable” version of Adobe software.

Minimum 8 GB (16 GB or more is highly recommended for better performance).

This version includes Camera RAW 14.3, which adds support for over 40 new camera models released in late 2021 and early 2022 (including the Sony A7 IV, Nikon Z9, and Canon EOS R3).

: Adobe does not produce or support "Portable" versions of its software. Official versions require installation via the Adobe Creative Cloud Desktop app.
