Hi there! I understand you're having trouble finding documents using the Y-Disk app on your iPhone with iOS 18.5. I want to make sure I fully understand the situation to help you better. Are you having trouble locating specific documents within the Y-Disk app, or is the app not showing any files at all? Also, are you using Y-Disk with a Y-Disk flash drive or just the app to manage files stored on your phone or cloud?

Once I know a bit more, I can guide you through some steps to troubleshoot this. Meanwhile, here’s a general approach that often helps when Y-Disk can’t find documents:

1. Check Device Connection: If you use a Y-Disk flash drive, make sure it is properly connected to your iPhone’s Lightning port. Sometimes debris or a loose connection can cause detection issues.

2. App Permissions & Access: Ensure the Y-Disk app has permission to access files on your phone or the connected drive. You can check this in Settings > Y-Disk app > Permissions.

3. Refresh the File List: Inside the Y-Disk app, try refreshing or reopening the file directory view to prompt the app to reload the files.

4. Supported File Formats and Locations: Confirm the files are saved in locations Y-Disk scans, such as the Y-Disk flash drive’s memory or designated folders. Also verify that the file format is supported by the app.

5. Verify Formatting of the Flash Drive: If you’re using a USB flash drive with Y-Disk, the drive should be formatted as exFAT or FAT32 to be recognized by iOS. If it’s formatted differently, the app might not show your documents.

6. App Update and iOS Compatibility: Make sure your Y-Disk app is updated to the latest version from the App Store, and that it’s compatible with iOS 18.5.

If you’ve already tried these or the problem is different, please let me know what steps you've done or any messages/errors you receive. I’ll guide you accordingly.

Does this sound like the problem you’re facing? Would you like me to walk you through checking the connection or permissions first?
