    ​I have a brother dp 540cj and it has a built in diskette drive.
    I have a ibm thinkpad latop. I connected a Memorex external usb floppy drive to the ibm thinkpad laptop. i'm copying 3 files from the ibm thinkpap (notepad) to the square 1.44 mb diskette. no problem, the 3 files were copied to the diskette.
    ​I turn on the brother dp 540cj, select file manager, insert the square diskette. the brother dp 540cj open only the file names on the disk. I try to open word text on either of the 3 files on the disk and the brother dp 540cj don't open the word text in any of the 3 files. I have been trying for several days to open the word text on the files using the brother dp 540cj and don't have any further instructio​ns for this problem. I tried saving the file names to all coding - Unicode, ansi utf-8 and can't fix the electronic problem.
