Open Program Management

Press PGM MGT key to access the file manager and navigate to the directory in question using the directory tree view.

Display All Files

Ensure all file types are visible by checking the file filter settings. Press the 'Show All Files' softkey if available to reveal hidden or system files.

Some TNC models hide .H files or system files by default - change filter to see everything in the directory.

Delete Directory Contents

Select each file or subdirectory within the target directory and delete individually. For subdirectories, recursively empty them first before deletion.

Verify files are not needed before deletion - back up important NC programs and data to external media.

Retry Directory Deletion

Once completely empty, select the directory and press the 'Delete' softkey or DEL key to erase the directory.

Check File Attributes

In PGM MGT, navigate to the directory and select it. Press the 'Properties' or 'Edit Attributes' softkey to view protection status.

Remove Write Protection

If write-protection is active, clear the write-protect flag from the directory and all contained files. This option may be under 'File Protection' in the properties menu.

On iTNC 530 and TNC 620/640, you can batch-change attributes by selecting multiple files with the wildcard selection feature.

Check Physical Media Protection

For CF cards, verify the physical write-protect switch on the card is not engaged. Remove and check the card if necessary.

Power down the control completely before removing CF cards to prevent file system corruption.

Attempt Deletion Again

After removing all protection flags, navigate to the directory and attempt deletion using PGM MGT interface.

Deselect Active Programs

Press PGM MGT and check the currently selected program in all operating modes (Manual, MDI, Auto). Select a different program from another directory or select no program.

On split-screen or dual-workspace controls, check both workspaces for active program references.

Close All Program Editors

Exit any open program editors or test run simulations that may be accessing files in the target directory. Return to standard operating mode.

Check Background Processes

Access MOD function and check for active background processes like file indexing or data logging that might be accessing the directory. Wait for completion or disable temporarily.

Perform Cold Start

If file locks persist, perform a control reboot by cycling power with a cold start. This releases all file handles and process locks.

Ensure no programs are running and machine is in a safe state before power cycling.

Retry After Reboot

After the control restarts completely, navigate to PGM MGT and attempt to delete the directory without selecting any programs from it.

Check Current User Level

Access MOD 7.6 (or MOD function 'User Management') to verify the current user login level. Directory deletion typically requires Setup or higher privileges.

Login with Higher Privileges

If logged in as Operator or limited user, logout and login with Setup, Service, or OEM credentials that have full file system access.

Default service password access varies by control generation - consult machine documentation or contact service personnel.

Check Directory Location

Verify the directory location. System directories in TNC:\ root or protected machine manufacturer directories may be restricted regardless of user level.

Do not delete system directories like SYS, SYSTEM, BIN, or manufacturer-specific folders as this will cause control malfunction.

Verify Network Drive Permissions

For network-mounted directories, check the server-side permissions. Access MOD function network settings to verify read/write access is granted for the mounted share.
