You may encounter sharing violation problems when attempting to copy trend data files from an active Trend server when using the XCOPY command.  

The XCOPY dos command is a high level copy which optimises copying by reading in as many files into memory as possible before writing them to the destination path. The mode in which XCOPY opens files is incompatible with file sharing and can result in dos flagging a sharing violation error. The low level COPY command does not suffer from this problem and should be used in preference to XCOPY.
