On occasion I find it necessary to utilize DOS while "in" Windows, and have found no problem accessing DOS running either file system—NTFS or FAT32.
Sometimes, working with file attributes or deleting is easier in DOS, especially with hidden files. Also, I like to PATH to a utility folder (wherein I have some DOS utilities). To do this it is necessary to access and edit the hidden file autoexec.bat.
Most know that Start — Run — cmd or Command will bring up DOS.
Then to edit the autoexec.bat file: at the prompt type: EDIT AUTOEXEC.BAT — and insert: PATH C:\UTILITY
It isn't necessary to change file attributes to edit a file.
Obviously—save the file; exit; reboot, for changes to take effect. The executable DOS files place in the utility folder are now available at the "C" prompt. That folder can either be made in Explorer or at the "C" prompt—C:>\MD UTILITY.
Another file management tool that I have found helpful is a stand-alone program called Filer which is imbedded in the DOS program ALT. I don't remember all that program (ALT) can do, but I keep Filer handy. I copy File to my Utility folder (I still like the name "Directory" and PATH to that folder in the autoexec.bat file. (Maybe I'll install ALT to see what all it can do—probably nothing useful other than Filer.
Also, I like to "see" autoexec.bat and config.sys files hidden files. The ATTRIB command is available to change the attribute of those, or any other, files. Of course, in a clean Win2K install there are no commands in either of these files.
So, to change the attribute from hidden to archive:
C:>\ATTRIB -H +A [drive:][path][filename]
("drive" and "path" are not necessary if file is in the current directory. OK—"FOLDER"
In addition to the foregoing, I have used, running Win2K in DOS mode,the following DOS commands, albeit on a limited basis: XCOPY, COPY, DIR, DEL, MOVE, LABEL, MD, RD, CD, MEM, VOL, VER (displays Windows version), PRN, and TYPE.
