Directory not empty error during server deployment

Hi, We are doing a server deployment (windows) on 4.2.2 release and encounter a 'directory not empty' error message. After reopening the select project file form and retrying 2 times we were able to continue. What does this error mean? Kind regards, Brian

Happened to me when windows explorer locked one or more of the deployment directories simply because it was my current directory or I opened a file. After closing windows explorer it was solved. Mendix deletes deployment files, if this fails you get this error.
