I've encoutered "DS_store" files a lot from X-Plane downloads. If my understanding is correct, this is basically the Mac OS equivalent of the "thumbs" file created by a Windows machine for whatever reason... perhaps it's just when you create an archive? Well, maybe it's only visible then...
"thumbs" files are "database files," and thus are probably automatically created by your computer to index some given content. Imaginably, when you create a compressed folder, this "indexer" which is normally invisible to you gets shoved into the compressed content. Because when someone else opens the said compressed folder, they will now see the "thumbs" file, as that's not
their indexing information.
And, because it's not their indexing information, they have no use for it. The first part of the statements are merely my theory on this matter. The second part should be entirely accurate.
Now, because "DS_store" is concievably the same thing as "thumbs," you should have no use for it...
...Throw it away.
