The Exchange Server Database Utilities (Eseutil.exe) /Y copy file mode is optimized to copy very large files efficiently. You can use the /Y switch to copy a database file or log file. However, the mode is not suitable as a general purpose copy utility.

Depending on disk and network conditions, copy file mode may be able to copy a file up to 20 percent faster than a normal copy because the copy file mode in Eseutil copies files in larger blocks of data.

 Because copy file mode does not accept wildcard characters (such as *.* to copy all files or *.edb to copy all database files), you must fully specify a file name and copy one file at a time.
