*.lck File error on startup


I’m running Kicad 8.0.2 on Windows 10 and whenever I start it up, I get the following error:

File ‘C:.…\xxxxxxx_pro,lck’ couldn’t be removed (error 0: The operation completed successfully.)

My design files are all on Dropbox with local folders, if that makes a difference.


With KiCAD closed delete any *.lck in your project’s folder, then reopen the project again in KiCAD.
