BCP stands for Bulk copy program, which is a command line utility, which is supplied with SQL Server 6.5.
A quote from books on-line. 'The bulk copy program (bcp) is a command-line utility that copies SQL Server data to or from an operating-system file in a user-specified format' There is quite a bit on this in BOL.
Prior to SQL Server 7.0 and DTS it was one the main tools used for copying data.
