File May Be Truncated When Copied to a Full Network Drive

Q161100



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.

A supported fix is now available from Microsoft, but it is only intended to correct the problem described in this article and should be applied only to systems experiencing this specific problem.
