Obviously, <a name="l4"></a>it is simpler. If you allow mission creep, pretty soon the 1040EZ looks just <a name="l5"></a>like the 1040 and the messed-up 1040EZ has no purpose. <a name="l6"></a> <a name="l7"></a>The Commodore 64 had a file system that was simple enough for peers in my <a name="l8"></a>generation to enjoy the thrill of knowing exactly what is going on at the <a name="l9"></a>hardware level and writing fun projects to access it. <a name="l10"></a> <a name="l11"></a>My primary design criteria is simplicity. If it is simple enough for only <a name="l12"></a>100,000 people to learn, lets try to make it simpler so that 1 million can learn <a name="l13"></a>it. <a name="l14"></a> <a name="l15"></a>Obviously, we don't do bad block tables, or redundant FATs. <a name="l16"></a> <a name="l17"></a>We use the simplest possible technique, a contiguous-file-only allocation <a name="l18"></a>bitmap, not </span><a href="/Wb/Doc/BlkChain.DD.HTML#l1"><span class=cF4>Block Chains</span></a><span class=cF0> or FAT tables. <a name="l19"></a> <a name="l20"></a>You can be a good toy or you can be a good professional tool, but not both. <a name="l21"></a>TempleOS's file manager will start too slowly once a few thousand files exist <a name="l22"></a>because the file manager makes a list of all files on start-up. <a name="l23"></a> <a name="l24"></a>Do not have more than a few thousand files or the file manager will not <a name="l25"></a>function. <a name="l26"></a> <a name="l27"></a>You are encouraged to keep your entire drive limited to, maybe, 100 Meg of files <a name="l28"></a>because you are suppoosed to operate as a kayak instead of a Titanic. If you do <a name="l29"></a>this, backing-up will be only a minute or so and you should do it at least once <a name="l30"></a>a day. <a name="l31"></a> <a name="l32"></a>Third party software should be run from ISO files or CD/DVDs directly, without <a name="l33"></a>installing to hard drive. <a name="l34"></a> <a name="l35"></a>Multimedia graphics and sound is, basically, forbidden. If you ignore this, all <a name="l36"></a>hell will break loose because memory will fragment with large files and the <a name="l37"></a>original vision of kayak hard-drive back-ups won't work. <a name="l38"></a> <a name="l39"></a></span><span class=cF8> <a name="l40"></a>* "Commodore 64" is a trademark owned by Polabe Holding NV. </span></pre></body> </html>
