Check all NC channels to verify the file is not currently selected or running. Use the HMI to view active programs in all channels.

Perform a complete reset of all NC channels (NC START button or RESET command) to clear any program buffers and release file locks.

This will stop all active machining operations. Ensure machine is in a safe state before resetting.

Exit any program editors or file browsers that may have the file open. Close HMI applications like ShopMill or ShopTurn if they are accessing the file.

Retry the delete operation. If the alarm persists, perform a power cycle of the NCU to clear all system file handles.

Power cycling will interrupt all operations. Coordinate with production before proceeding.

Check the file attributes via HMI Services > File Manager. Verify if the file shows write-protection or read-only attributes.

Log in with higher access level (Service, Manufacturer, or Administrator password) to obtain deletion rights for protected files.

Only use elevated access levels if you are authorized. Document any changes made at this level.

If attempting to delete system directories (WKS, CMA, SPF, etc.), verify you are not trying to delete protected system folders which cannot be removed.

Never delete system directories. This can render the control inoperable and require complete system restoration.

Remove write-protection flag if applicable using file properties, then retry deletion. Check MD11210 (access rights configuration) for user-specific restrictions.

Access Service mode and run file system check utility (CHKDSK equivalent). Navigate to Commissioning > System Data > Check File System.

File system checks can take significant time. Perform during scheduled maintenance windows.

Review the NCK and PLC alarm logs for previous storage-related errors (10210x series alarms) that may indicate media problems.

If the specific file is corrupted, attempt to access it via external methods (PCU50 network access, DHCP connection, or CF card reader) and delete from Windows level if accessible.

Direct Windows-level file manipulation should only be done by qualified personnel to avoid system file damage.

If file system corruption is confirmed, backup all NC data and consider CompactFlash card replacement or NCU hard disk maintenance. Restore from known good backup after media replacement.

Always maintain current backups before any storage media maintenance. Complete system restoration may be required.
