Recently I downloaded the Simplified Chinese edition of MSDOS6.21 from http://www.450mb.com/users/kinglion/S008/. After re-reading its IMG files into new floppy disk images with HD-COPY, they can be read with WinIMage! But I found that there are many folders inside whose filenames and extensions are both "?", and they cannot be deleted! Nor can they be extracted with Undiskw 1.6! Although it does not affect use, it still feels bad! The original IMG, however, can probably be extracted with Undiskw 1.6, but the first disk is the boot disk, and after extraction the boot function is gone! Looking for a solution! Or if anyone can send me an IMG image of the first floppy that has no such folders, can be read with WinImage, and still has boot functionality, please email it to me at afnspy@gmail.com! Thanks in advance!!!
