I was working on some other projects recently, but now I decided to update DOSBox LFN build once again after discussions with some other DOSBox users who are interested in this feature on other forums. By now I have already added the ability to turn LFN support on or off to the DOSBox LFN version. …

I guess another option is to use (external) shell command executables which support LFN and then have a switch to disable the built-in dosbox shell commands where applicable. I think the implementation of DOS version emulation logic will be simpler to understand and easier to use, but in particular …

You could use setting the reported major DOS version to 7 (VER SET 7) as a toggle for LFN support... just a thought. ;) Thanks for the suggestion. It probably will actually work as this was also what I had done when I added LFN support to Paul Houle's Enhanced DOSKEY (http://paulhoule.com/doskey/) …

I think you are really talking about the implementation of LFN support. A good implementation of LFN will almost never cause any problems because the games or applications in the first category (i.e. those expect or rely on 8.3 names) will never call the AX=71xx functions, but will instead rely on …

I believe the official mscdex driver does not support long file names. So, your code would not provide long file names to 95 (or DOS) while accessing CDROM files via the real mode driver. Thanks for making me aware of this. I will take a look at it. The combination of SHSUCDX and DOSLFN will give …

LFN support will in most cases not give any benefit to DOS games or applications, and in fact can cause problems because there is an expectation of (or even reliance on) the 8.3 limit. The exception is games or apps developed to work in DOS 7 or the NTVDM where long filenames are used; however, …

I am not sure what happened to my earlier post, but are there any DOS games that require long file names, let alone can even read them? Good question! Personally I never played a commercial DOS game that would *require* LFN support myself, but since I am not a real gamer this does not mean there …

If you use SVN "properly" you can just make a diff against it (svn diff > lfn.diff) and post that. Or find some other way to make a diff/patch (I'm not using Windows anymore so I can't really say). Moving it to the patches forum as well (thread starting is prohibited to keep that forum kind of …

DOSBox is a great software which will emulate DOS under various operating systems such as Windows. Unfortunately, the latest official version of DOSBox still lacks Long File Name (LFN) support, which is a very important feature implemented since MS-DOS 7.x and Windows 95. I have seen many DOSBox …
