Default request for additional filetypes for attachments

Could we possibly have the following filetypes added to the list of files allowed to be attached to posts?

.rar
.7z
.lzma

Right now the only compression formats allowed (without renaming, which can be somewhat of a pain) are .zip, .gz, and .bz2. For some types of files, the above three can provide better compression, and in cases when the poster is reasonably sure that the intended downloaders will have access to the requisite decompression programs, it would be quite useful to have them available.

It seems like a lot of work for very little gain.

With so many free places available to upload large files, the space we have here should just be for small things.

Post a poll, get a majority vote and convince more than half of the super mods and we will make it happen.

Also, you could just put them in a zip file and remind users of the need for a two-stage decompression.

Sounds like a diving course.

Or just rename the file and state that in the post.

I think zipping the (.7z, .rar, or .lzma) file like cheesehead suggested would be the best option. Besides, with the attachment limits, I can't see the slightly better compression ratio of these methods being terribly useful (in terms of extra upload/download times). Now, if you happened to have a file whose size is just on the border, such that it would fit with .7z but not with .zip, then you can put the .7z inside a .zip.

Okay, no problem. I was mainly thinking that possibly one could help reduce the forum's disk usage a bit by using more efficient compression formats, but then again, when the savings are on the order of a few KB, it's probably not going to make any difference in the long run.

OTOH, "supporting" additional formats ought to be trivial -- so trivial, in fact, that we shouldn't even be having this discussion. Just do it already!

If we try hard enough, we could use more bytes discussing the change than we hope to save through the change...

Ok. Here's something to consider. I might use my *favorite* compression utility to compress in some particular format because that is the best format. However, whenever I need to upload a file to the forum, I need to switch from my *favorite* format (*sob*) to zip (*yuck*) and then switch back. Saves me a lot of hassle if I could just upload my *favorite* format. [That's a lot of * ]
