DOCUMENT:Q161100 08-MAY-2002 [win95x] TITLE :File May Be Truncated When Copied to a Full Network Drive PRODUCT :Microsoft Windows 95.x Retail Product PROD/VER:: OPER/SYS: KEYWORDS:kbenv kbnetwork osr2 win95kbfixlist ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows 95 - Microsoft Windows 98 ------------------------------------------------------------------------------- SYMPTOMS ======== If you use Windows Explorer on a Windows-based computer to copy a file to an SMB (Server Message Block) server using the Microsoft Client for Microsoft Networks, the file may be truncated if the server's disk is full or nearly full. The copy operation may seem to succeed, and no error message is displayed. However, some data at the end of the file may be lost. CAUSE ===== This can occur if the amount of free disk space on the server is slightly less than the size of the file being copied. RESOLUTION ========== To resolve this issue, make sure the disk on the network server contains sufficient free space for the file being copied.
