accessing older that recent files on photoshop

Use your operating system's file manager (Win File Explorer or Mac Finder) and sort by date modified. 

In Photoshop for iPad OS, if the files you are working on are all Photoshop Cloud Documents, then all of your Cloud Documents (not just the Recent ones) should be listed under the Your Files section.

In addition, if the file is a Photoshop Cloud Document, it won’t show up in searches on an iPad or computer desktop, because it exists only on the Adobe Creative Cloud server, not locally.

If you did save or export it to your local device, then it should show up in an OS search.

Most Photoshop for iPad files are saved to the Cloud, but you can export them to Files or Photos. You say that you saved it, but psdc files on the iPad don't need to be saved, as saving is automatic by simply closing the file. What process do you think you might have used for "saving"?

Have you looked in Files? Click on each tab, starting at the top with "Recents"

Hi @Indre30170310729e it is up to the user to manage your files. If you can't recall where you saved them and they are not showing on a HD search, there isn't much else we can do software-wise. Did you run a full search of all locations?
