Accessing documents stored in iCloud
This article concerns the
iOS
app.

Files in your iCloud Drive may be linked and opened in Texpad using Files app as described in apps/managing-documents/ios/non-texpad-storage/using-files-app . There is a special section in the File Browser for iCloud, but the mechanism underlying the file access is the same for iCloud as any other app or service that has implemented full Files app support.
