All my files from the past month are suddenly gone

[Jonathan236523024b3m]

I mainly work from Adobe Illustrator and after downloading the update Wednesday night, when I woke up Thursday morning all of the files I've been working on in AI from the Creative Cloud were gone. Folders are sending me back to libraries from months ago as if no work has been done in weeks. Some libraries were completely missing. I had many important files saved in these libraries for work that I really hope are not gone.

Hi Jonathan,

We are sorry to hear about your difficulties of missing files in AI within Creative Cloud. Could you please let us know what update was installed in your system?

Also, share the below details to investigate the issue

1. What Operating System and its exact version.
2.  Creative cloud version
3.  if the missing file issue is with other applications as well in the creative cloud.

Thanks

Neelam
