As far as I can tell, this:
won't create two copies of the DMP file (one on your D disk drive, another one on E). This is what documentation says (navigate to the FILE parameter):

When Export reaches the value you have specified for the maximum FILESIZE, Export stops writing to the current file, opens another export file with the next name specified by the FILE parameter, and continues until complete or the maximum value of FILESIZE is again reached. If you do not specify sufficient export filenames to complete the export, Export will prompt you to provide additional filenames.

In other words, it means that EXP utility will write into your D:\TST\2.DMP until it reaches FILESIZE limit (this parameter specifies maximum size of each DMP file). Then it'll continue export into E:\TST\2.DMP file. If it reaches FILESIZE limit, it will stop and ask you to specify the third (or fourth, fifth etc.) filename until the whole export is done.

Finally, it means that you'd rather create your own (operating system) exporting script (that would be a .BAT in your case) which would a) create one export file on disk D, b) copy it to disk E. Maybe it is possible to do that using EXP itself, but I don't know how to do that.

Create a script with the commands to export and copy the file:

SET PGMDIR="F:\oracle\product\10.2.0\db_1\BIN"
cd /D %SRCDIR%
%PGMDIR%\exp scott/tiger file=1.dmp statistics=none
copy 1.dmp %TGTDIR%\2.dmp /B
