Last week all was fine on my iMac, then today all my files (Documents, Pictures, Pages) whether stored in Finder or Desktop all come up with the same message when I try to open them in Preview: "(Name of File) is damaged and can't be opened. You should move it to the trash." I have not trashed anything. Is it a problem with Preview? Please advise.
iMac 21.5", macOS 10.13
Run Disk Utility First Aid on the drive. I've seen a couple of systems which use the APFS file system have this issue where Disk Utility First Aid could not repair the volume so it required erasing the whole physical drive and reinstalling macOS or restoring from a backup. I still don't know if this is just another APFS issue or a hardware issue.

Please navigate to the Mac App Store and download the free version of EtreCheck OR please click www.EtreCheck.com where you will find the app. Once you downloaded the free app and created the report please post it as your reply to this message. In order to post it, please use the following link for more detailed instructions on how to correctly include the results:

We can then look for obvious issues that may be causing your problem.
The EtreCheck scan only told me there were "no major problems." Ha! I think a recommendation to trash all your files is "major." HWTech's suggestion to simply run Disk Utility First Aid corrected everything, and I have full access to all my files. What might have caused this in the first place? Thanks a million, HWTech!
Please post the report so we can view it.
All files have been restored by running the Disk Utility First Aid. I hope you can understand why I’m not interested in posting anything I don’t need to. Anyway, I have deleted EtreCheck.
All files are "damaged...move it to the Trash."
