Is there a way to move my iCloud Photos directory? It is stored on my C: drive and I don't have much space. Can I move it to another disk?

Hi there You_Know,

Your iCloud Photos library can only be stored on the C: Drive on a PC:

Note: You can only change the location to another folder on the C: Drive. External drives aren’t supported.

Keeping that in mind, we'd suggest trying to clear some storage space on your C: Drive. Reaching out to the manufacturer of your computer may be helpful for some additional guidance on how to do that.

Take care.
