file extensions
-
I have a lot of XML files that are given other extensions, and text files that are given other extensions, and it would really be nice to have a naming scheme that would allow those facts to be represented in the name (and file associations...)

Yeah, xml is one of those strange cases since the files should really be grouped by schema. .xml.schemaName or the reverse would be nice. So would meta data that was shown in explorer. I don't like the way office handles it's xml files. It actually scans the xml file and shows it's type in explorer. That really sucks.

Is there any (compelling) reason to continue using 3 character file extensions? I am in the process of choosing the extensions that my app will use and I am leaning toward using 4 - 6 character extensions. The main reasons are: To avoid colisions with extensions that are used by other apps. The extension names do a better job explaning what kind of data is stored in the file. I am worried however, because it seems almost applications still use 3 letter extensions for their files. Aside from compatibilty issues with old 8.3 format DOS systems which I think for 99% of current applications isn't an issue anymore, why are people avoiding using longer file extensions for new formats?
Depends on what kind of inter-operability you require. Will your files be processed by lots of other applications most of which are unkown to you (ex mp3 files)? If not then choose whatever you want. I know applications such as SolidWorks (3D CAD) use .sldprt, .sldblk, .sldasm, etc. But for Office there's probably thousands of home grown tools and code out there that assumes 3 character extensions and going with something else would only wreak havoc.

Or to be able to associate apps, icons etc with xml files based on their contents rather than just have one app and icon covering all xml files. I have a shell extension that does just that!

For our software, we don't limit ourselves. In fact, since changing to longer extensions we have found that we don't need to worry about conflicting with other applications. It's much easier to have a descriptive file type, so rather than using something like DOC you could actually call it Document.

I'm using them myself in a few places, it's better. The only reason against I can imagine is users that are not yet adjusted. Worsened by the likelyhood that they still use some tool that isn't LFN aware and "suddenly lose their data anytime they copy it to somewhere else randomly without having done anything at all." So the question for you is: can you train a few luddites people dedicated to not changing a workign system, or is their opinion so valuable to you (or their antics so devastating) that you rather not dare tickling them. One thing to be aware is the pattern matching of file search. If you search for "*.zoidfiles", Windows will return all files with the extension ".zoi" as well - because that would be the extension of the 8.3 filename. (that's why, *.html also matches *.htm)

Thanks for the tip, didn't realize that the FindFirstFile Api worked this way.

If you sent my mom a Word document with .document as the extension she'd delete it thinking it was a virus or some such. .doc is ingrained (as is .xls, .pdf, .txt, .exe, .ppt etc.) For new apps I'd say think of who your users are. If they are techies then longer extensions are fine (.xaml, .application, .csproj, .config etc.) If they are non-techy users then think hard before using more than three letters.

Microsoft use a six letter one in: Application.exe.config Although that's also a double extension - are there any rules for double extensions?

Yes. Try sending one as an attachment through the company spam filter...

That they are misleading if you have "hide known extensions" turned on?

Your batsmen never had a problem - even in that whitewash, they performed very well. It was your bowling that was killing you.

One last thing to be aware of: Optical disc standard ISO 9660 http://en.wikipedia.org/wiki/ISO_9660[^], check the restrictions section. Different formats have different restrictions, one of them is a 3 character extension, another is no file names can have more than one dot in it. I'm sure there are other "standards" that have similar restrictions, but if you're going with life file system file associations, there shouldn't be any reason why you can't have extended extensions. Of course, there's legacy software to take into consideration too.

I thought _MAX_EXT would kill that idea but actually, it has a value of 256.

What it would come down to is target market. I was just thinking about that myself -- and what it came to, is that in the next year my company will be fully windows Vista, so I don't think that will be a problem for me, when I go forward. I'm in a limited market and can control my environment, but if I were selling, I would need to consider compatablity. If you know your target, then that makes the decision for you. Michael White
