MS-DOS 6.2 Step-Up May Leave Temporary Files If Interrupted

If MS-DOS 6.2 Step-Up is interrupted while it is patching files, it may leave zero-byte files in the root directory. Also, patch files (*.??#) may be left in the directory containing your MS-DOS 6.0 files.


The patch process used to update your existing MS-DOS files creates and uses temporary files. These files are created in the root directory and are deleted by Setup when it exits in a normal no-error condition. Whenever Setup is aborted abnormally (such as by a power failure), the temporary files are not deleted.


The zero-byte files left in your root directory (and the patch files in the directory containing your MS-DOS 6.0 files) can safely be deleted after you have successfully installed MS-DOS 6.2. The temporary files in the root directory typically have names including numbers such as 10 or 11.
