All files you mentioned are required for each of these apps and cannot be removed. To save space on your SSD, you can install CC apps (not the creative cloud desktop app) on a secondary drive. By default, your Creative Cloud apps are installed in the Program Files folder (Windows).
You can change the default install location(although it is not recommended but can be done if disk space is too low). Open the Creative Cloud desktop app and click the gear icon at the top right of the window. Choose Preferences > Apps > Install location > Change. Navigate to the desired location and click Open. Your new install location appears in the menu.
Hope that helps.
Thank you for the reply. I have enough space on the SSD for the files and the intention of having an SSD is to improve the Photoshop performance/startup time, so I will leave them there. However, it seems like very sloppy programming to require multiple copies of the same file e.g. font files for each program.
Is there any way to tell the applications where the fonts are stored, and reduce to one copy of each?
