Summary

If GibbsCAM displays the error:

Couldn't Save File to Specified Location

the software was unable to write the part file to the selected location. This typically indicates that the destination folder could not be found or that Windows prevented GibbsCAM from creating or modifying files in that location.

Common causes include insufficient folder permissions, disconnected network drives, antivirus or endpoint security software blocking file operations, or attempting to save to a location that is no longer available.

This article explains how to identify and resolve the most common causes of this error.

Before You Begin

Important: During the save process, GibbsCAM creates a temporary .ZOOB file before writing the final .VNC file. If Windows or security software blocks creation of the temporary file, the save operation will fail.

Symptoms

You may experience one or more of the following:

  • GibbsCAM displays Couldn't Save File to Specified Location.

  • The part cannot be saved.

  • The file saves successfully to some folders but not others.

  • Saving to a network location fails.

  • The error began after installing new security software.

Procedure

Step 1 – Verify the Save Location Exists

Confirm that the destination folder is still available.

If saving to:

  • A network share

  • A mapped network drive

  • A removable drive

verify that the location is connected and accessible.

Try creating a new text file in the same folder using Windows Explorer.

Expected Result

The destination folder is accessible and allows files to be created.


Step 2 – Verify Folder Permissions

Ensure your Windows account has permission to write to the destination folder.

  1. Right-click the folder.

  2. Select Properties.

  3. Open the Security tab.



  4. Verify that your account has permissions to:

  • Read

  • Write

  • Modify

If necessary, contact your system administrator.

Expected Result

Your Windows account has permission to create and modify files.


Step 3 – Test Saving to a Local Folder

Determine whether the problem is specific to one location.

Try saving the part to a local folder such as:

C:\Users\<username>\Documents


If the save succeeds locally, the issue is likely related to the original destination rather than GibbsCAM.

Expected Result

The file saves successfully to a local folder.


Step 4 – Check Antivirus or Endpoint Security Software

Security software may prevent GibbsCAM from creating files.

If permitted by your organization's IT policies:

  1. Temporarily disable antivirus or endpoint protection.

  2. Test the save operation.

  3. Re-enable protection immediately after testing.

If the issue is resolved, configure exclusions for:

  • GibbsCAM

  • .VNC files

  • .ZOOB files

Note: The .ZOOB file is a temporary file created during the save process and is normally deleted after a successful save.

Expected Result

The save operation completes successfully.


Step 5 – Verify Available Disk Space

Ensure the destination drive has sufficient free space.

Low disk space can prevent temporary files from being created during the save process.

Expected Result

Adequate free space is available.


Step 6 – Repair the GibbsCAM Installation (If Necessary)

If the error occurs when saving to any location:

  1. Open Apps & Features or Programs and Features.

  2. Select GibbsCAM.



  3. Choose Modify > Repair.

  4. If the problem persists, uninstall GibbsCAM.

  5. Restart the computer.

  6. Install the latest supported version of GibbsCAM.

If the issue persists after reinstalling, investigate Windows permissions and endpoint security software.

Expected Result

GibbsCAM saves files normally.

Expected Result

The part saves successfully, and the temporary .ZOOB file is automatically removed after the final .VNC file is written.

Additional Information

Why GibbsCAM Creates a .ZOOB File

During the save process, GibbsCAM first creates a temporary .ZOOB file.

Once the save completes successfully, the temporary file is renamed or replaced with the final .VNC file, and the .ZOOB file is automatically deleted.

If the save process is interrupted or blocked, the temporary file may remain on disk.

Common Causes

  • Insufficient folder permissions.

  • Destination folder no longer exists.

  • Disconnected network drive.

  • Antivirus or endpoint security software blocking file creation.

  • Insufficient disk space.

  • Read-only folders.

  • Network connectivity issues.

Best Practices

  • Save work to reliable local or network storage.

  • Verify write permissions before saving to shared folders.

  • Configure antivirus exclusions for GibbsCAM if recommended by your IT department.

  • Keep regular backups of important part files.

  • Investigate any remaining .ZOOB files, as they may indicate interrupted save operations.

Troubleshooting

  • Problem: The error only occurs when saving to a network drive.

Possible Causes

  • Network share unavailable.

  • Insufficient network permissions.

  • Network interruption.

Resolution

Verify connectivity, permissions, and network availability.


  • Problem: The error occurs in every folder.

Possible Causes

  • Endpoint security software.

  • Windows permissions.

  • Damaged installation.

Resolution

Test with antivirus temporarily disabled (if permitted), verify permissions, and repair the GibbsCAM installation.


  • Problem: A .ZOOB file remains after the failed save.

Possible Causes

  • Save operation was interrupted.

  • Security software blocked completion of the save.

Resolution

Verify folder permissions and security software settings. If appropriate, see What Is a .ZOOB File? for additional recovery information.
