"Enhanced file system: MS-DOS 6.22 introduced support for large hard drives and improved file system reliability."
Need to ensure that each word is replaced with three different synonyms, even if it's part of a compound term. For example, "Microsoft Disk Operating System" is a proper noun, but each word within it isn't. However, the instruction says to keep names intact, so perhaps the entire phrase should remain as is. Wait, the user said "Change every word with 3 synonyms in format opt3. Keep names intact." So if the name is a proper noun like "Microsoft Disk Operating System", we leave it as is. However, if a word is part of a name, should that word be changed? Maybe not. For example, "Microsoft" is a name, but "Disk Operating System" is part of the name. I think the user wants the names (like MS-DOS) to stay the same, but the rest of the words are to be replaced. Download Ms-dos 6.22 Full HOT- Iso
