Photoshop won't open older PSD files after cleaning disk with DaisyDisk

Automatic cleaning programs are never a good idea. If you can't get enough space using your OS's disk management/cleanup utility, and you aren't sure what is safe to delete manually, then don't touch it, and don't use a cleaning program, unless you absolutely know that it will work. (I don't know about DaisyDisk, but I haven't yet encountered a program that is 100% safe.) I have worked on many borked systems throughout the years due to this, mostly Macs with freeware deleting critical system files, but a fair number of Windows machines as well. Manually repairing/replacing and registering missing system files is a real pain, so you're lucky it was just the CC apps.

Unfdortunately, automated cleaner software is often a problem, as it can delete important files. You should do the testing per Pete's suggestion but you may need to reinstall the Adobe suite and possibly even your operating system. When multiple applications error out, its likely shared components that they all rely on.

What kind of errors pop up?

Hi @patrik_7592 ,

Sorry to hear about this trouble after using that clean up tool -- Some thoughts/questions:

1. Do you have another computer to test if these PSD files are able to be opened?
2. Are you able to import the PSD files into Photoshop web?  https://creativecloud.adobe.com/cc/photoshop
3. In Finder, if you select a PSD file and press spacebar, does macOS preview the file ok?
4. What happens when you try to open these PSD files in Photoshop desktop? Do you get any errors?
5. Would you be able to share any of the affected PSD files with us so we can test them out?

Regards,

PG
