This may, however, provide unexpected results unless you are aware of the way SourceSafe compares the checksum. MORE INFORMATION ================ SourceSafe computes the checksum with the Update command. For the sake of efficiency, if Compare is not set to Checksum, SourceSafe doesn't compute the checksum value. As a result, when you first set Compare equal to Checksum, the checksum value is not available for comparison. When you use the Get command, SourceSafe continues to get the files until they are Updated. To resolve this issue, update the files immediately after setting Compare to Checksum. NOTE: Because the checksum is computed on each update, all SourceSafe users should set Compare equal to Checksum if one user does. For more information on how to improve the performance of the Get command by using the Compare to Time setting, please see the following article in the Microsoft Knowledge Base.
