I took a good look at this code, and you must have some type of loop running, because you should not see the second "_" at the end there. There is no place in the code that you submitted that would place something there. Something that I saw when testing this code is that after you append the file Bin_file_name, the appended file is now saved in Bin_file_name. So for example, you may have Bin_file_name as "hi". After the append, Bin_file_name is actually "hi_" Then after your next two lines, Bin_file_name would be "hi_friend.dat" Now if the loop goes through again without you resetting the value of Bin_file_name it will tack on the "_" at the end of "hi_friend.dat" to "hi_friend.dat_" If you want to reset the value of Bin_file_name, just use Fmt (Bin_file_
name, "%sI have attached code you can look at as well, and I spelled the file name as Fomat, which should be Format. Oh well. Thanks.
