DOCUMENT:Q92791 06-OCT-1999 [win3x] TITLE :File Manager Does Not Allow Copying of Open Files PRODUCT :Microsoft Windows 3.x Retail Product PROD/VER:WINDOWS:3.1,3.11 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows for Workgroups versions 3.1, 3.11 - Microsoft Windows versions 3.1, 3.11 ------------------------------------------------------------------------------- SYMPTOMS ======== If you use File Manager to copy a file that is being used by another application, the following error message is generated: Access denied, source file may be in use. 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. CAUSE ===== 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.
