DOS is a general acronym for "Disk Operating System", though it came to refer to the operating system used in the IBM PC, particularly Microsoft's MS-DOS.

One key to working with DOS is to understand the file system. This is not just about organizing files, though that is certainly a part of it, but also about keeping your system running smoothly and recovering lost files in some circumstances.

Ahhh, the 1980's. FAT and Assembler. This is exactly why we drank beer when we wrote code till 3 am. It was a good program sir..

Good blast from the past

Man, just entering and he makes me feels old (I'm old)

This is a very good one.

Complete, clear and sufficiently simple explanation of how FAT works, understanding this old filesystems is a very good way to enter the new filesystems (which intend to solve many of the problems Ahuka mentions).

And remember the DOS days is also very nice.

Thanks for the shows and the work of this community.

Greetings from México.

Excuse my bad english, I learned from a TRS80 manual.

Thank you

I'm glad you enjoyed it. Your English is better than my Spanish at this point, but I am learning your language, and hope to visit Mexico. I am already planning a trip to Spain.

I'm not old enough.

Was RAID available for MS-DOS? If so, could you perform a RAID 1 using floppy disks?

I have to admit I never looked into it. When I was running DOS in the 1980s even getting a hard drive was something of a novelty.
