A PSDC file is an Adobe Photoshop document saved in the Adobe Photoshop Document Cloud (PSDC) format. It contains an image in the same format as a .PSD file, but is stored in the cloud using via Adobe's cloud documents system. The file is automatically updated when it is opened and modified on different devices.

PSDC file open in Adobe Photoshop CC 2020 The PSDC format was introduced in November 2019 with the release of Photoshop for iPad and Photoshop CC 2020 for Windows and macOS. The purpose of the format is to allow users to work on the same PSD document on their computer or iPad and have their modifications synced so the document is always up-to-date. The PSDC file format is the same as the PSD format, which includes support for image layers, adjustment layers, layer masks, annotations, and other Photoshop-specific elements. However, the PSDC format also supports caching of edits made to a document when a user is working on it offline. Then, when the user connects to the Internet again, the changes are synced.
