APC File Prefix in Lightroom Mobile

[BernardMR]

I note that in Lightroom for iOS my files are prefixed APC_

Does anyone know what APC stand for?

[Michael J. Hoffman]

In general, this means it was an image captured by the camera app within Lightroom Mobile. Any image imported from  the iOS camera app, or other cameras, maintain their original naming.

While I don't know the exact meaning of the acronym, I've always thought of it as "Adobe Photo Camera."
