If you use File Manager to copy a file that is being used by another application, the following error message is generated:
However, if you use the COPY command from MS-DOS Prompt to copy a file that is being used by another application, the file copies successfully.
For security reasons, File Manager refuses to copy files that another application might be in the process of changing. The COMMAND.COM portion of MS-DOS does not check to see of if the file is being changed by another application.
NOTE: To avoid losing data, do not try to copy files that are being modified by either Windows-based or MS-DOS-based applications.
