DANGER! WILL ROBINSON!!!
Authored by: kaih on Jun 27, '06 07:58:21PM
No, seriously, depending on what kind of data is stored on your server this could be a VERY BAD IDEA
If you have anything on the server that still uses a resource fork, this will break it. No questions asked. No warning given, and no chance of fixing it, other than restoring from another source.
In particular, even in our wonderful, shiny Mac OS X "resource forks are depricated" world, certain things still rely on resource forks. Microsoft Office is a Carbon app. It is not an app bundle, and it needs a resource fork. It won't launch if it's resource fork is broken.
Fonts - lots of older fonts rely on having important information in their resource forks. I've seen the results of a server where someone went through and cleaned up the dot-underscore files. No, it wasn't pretty. Their entire font collection was broken. Fortunately, they had it all on the original CDs and could recover it, but it was a pain.
Other things like custom icons, finder comments, finder labels and all sorts of other kinds of metadata is stored in these files.

Only delete these files if you really know what you're doing, and you have a recent backup. No, really...

Yep, don't frivolously delete "._" AppleDouble and .DS_Store files.

There's been some mention of the consequences of doing that (among other things) in the recent Metadata support thread on the darwin-dev list. It's an interesting discussion if you want to learn more about those kinds of technical details.
