Access the HMI and navigate to Commissioning > Memory Configuration or System Data to check available memory on NC partitions.

Check the target directory size using the file manager. Look for space usage in /user, /oem, or /addon partitions depending on copy destination.

Delete unnecessary NC programs, old backups, or archived files from the target partition to free up space. Ensure at least 10-15% free space remains.

Always backup important programs before deletion. Document what files are removed.

Retry the copy operation after freeing sufficient space. If issue persists, consider using external storage or USB device for archiving old programs.

Check current user access level. Navigate to System > User Management and verify you have level 2 (service) or higher permissions required for file operations.

Verify the source file is not currently open in an editor or being executed. Stop any running programs and close all NC program editors.

Ensure machine is in a safe state before stopping program execution.

Check file attributes using the file manager. Right-click on the file and verify it is not marked as read-only or system-protected.

If the file is on external USB media, check that the media is not write-protected (physical switch on USB device). Remove and reinsert the USB device, then retry.

Attempt to open the source file in the NC editor to verify it is readable and not corrupted. Look for unusual characters or truncated content.

Check the system logbook (Diagnostics > Logbook) for previous file system errors, battery alarms, or storage-related warnings that may indicate broader issues.

Perform a file system check if available in service mode. On 840D sl systems, use Startup > Service > File System Check. Allow the process to complete.

File system check should be performed during scheduled downtime. Ensure UPS or stable power supply is connected.

If the file is confirmed corrupted, restore from a known good backup. If copying from external media, verify the source media on another device and copy using alternative method (import function vs. direct copy).
