How do I fix 'error-50' while moving a videos folder from iPad to external drive?

Yesterday, when trying to move a folder with video files inside of it out of my iPad into my external drive, I got an ‘error -50’ message. When I tried to move an empty file from my external drive into my iPad I got a ‘Couldn’t communicate with a helper application’ message.

I’ve tried using my external drive’s software to run first aid (no errors), moving a file from my mother’s laptop to the drive (worked, no errors and able to open the file), tried moving individual video files out of a folder into the drive (worked, no errors and able to open the file - I’d just keep doing this if I wasn’t so nit-picky about organising my TBs of files), tried creating and deleting files from the external drive (got an error or a ‘Can not move to ‘501’’ message). I’ve restarted my device twice and tried cleaning the USB port by blowing on it and checking for anything that could visibly show me what’s wrong.

I have to assume my iPad has somehow broken. What next steps should I take? Is there any more troubleshooting methods I could try at home? Thank you.

Attempting to move multiple gigabytes (terrabytes?) in a single operation can be challenge for any computer - and rarely works well (if at all) on a mobile device that may lack the required system resources. Even the iPad Pro models may struggle with extremely large file copy/transfer operations.

You would be best advised to break-down the task into smaller manageable chunks. Keeping your iPad connected to its Power Adapter throughout the process may help, as this will help to ensure that your iPad can operate at maximum performance.

If your iPad is not operating as expected, try a forced-restart - as this will often clear an isolated software issue:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

Press and quickly release the volume button nearest to the top button.
Press and quickly release the volume button farthest from the top button.
Press and hold the top button.
When the Apple logo appears, release the top button.

If the problem persists after performing the restart, it may be necessary to reset your iPad settings. While this reset will not cause any loss of data, as a precaution, it is always wise to ensure that you have a current iCloud or iTunes backup before performing the reset:

When you are happy to proceed, you can perform the reset from iPad settings:

Settings > General > Transfer or Reset iPad > Reset > Reset All Settings

If the problem still doesn’t clear, the next step is to reset the iPad to factory settings:

Otherwise, you would be best advised to seek assistance directly from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively and perhaps easier, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to assist with troubleshooting:
