If you use Windows Explorer on a Windows-based computer to copy a fileto an SMB (Server Message Block) server using the Microsoft Client forMicrosoft Networks, the file may be truncated if the server's disk is fullor 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.
This can occur if the amount of free disk space on the server is slightlyless than the size of the file being copied.
To resolve this issue, make sure the disk on the network server containssufficient free space for the file being copied.
