Disable the File Explorer Preview Pane

The Windows File Explorer Preview pane can inadvertently lock background files like Personal.xlsb. Disabling it is a fast and common fix.

When the Preview pane is active, Windows creates a temporary lock on the file to render a visual preview. If Excel attempts to access Personal.xlsb simultaneously, it triggers the locked for editing error.

1
Open File Explorer

Press the Windows Key + E on your keyboard to open a new File Explorer window.

2
Access the View Tab

Click on the 'View' tab located at the top of the File Explorer window.

3
Disable Preview Pane

In the Panes section, check if 'Preview pane' is highlighted. If it is, click it once to disable it. Close File Explorer and relaunch Excel to test.

Frequently Asked Questions

Why is my Personal.xlsb file suddenly locked for editing?

This error typically occurs when multiple instances of Excel are running at the same time, or if the Windows File Explorer Preview pane is holding the file open in the background to generate a preview.

Will deleting Personal.xlsb remove all my macros?

Yes, deleting the Personal.xlsb file will permanently remove any custom macros you have recorded or stored inside it. Always back up the file by moving it to your Desktop instead of deleting it.

Do Microsoft's File Block Settings cause the Personal.xlsb locked error?

No. File Block Settings are designed by Microsoft to restrict the opening or saving of legacy or potentially dangerous file types for security reasons. They are completely unrelated to file locking or simultaneous instance conflicts.

Can multiple users on a network share the same Personal.xlsb file?

No, Personal.xlsb is intended for local, personal use only. If multiple users need access to the same macros, you should save the macros as an Excel Add-in (.xlam) and distribute it, or utilize a shared network workbook.
