I just installed Developer Tools.
I only need few apps in Developer>Applications-folder. I dont need Documentation etc.
Can i compress rest of Developer-folder without any side effects?
Why do you want to compress it? Do you have limited disk space? I’m going to bet that you don’t need the disk space, but if you do you’re likely to run into a lot of problems trying to do development. Why not just work around the apps and files you don’t currently use? Another thing to consider, is that you may change your mind about some of those apps and other resources that you’re so quick to dismiss today. Over the years I’ve sampled and occasionally used some of lesser-known specialty tools that apple hides in it’s developer directory. Just because they don’t seem important at this stage of the game, they may become more useful to you as time goes by.
I’m not sure what you’re planning to use the developer tools for, but I find the documentation to be of some importance. While the 1.5GB HD space price tag is a bit high, it’ll seem worthwhile when your internet is out or you’re sitting somewhere with hours to kill and a laptop with no internet connection. In fact, I almost always use the local documentation, unless the apple docs I’m looking for aren’t distributed with the devtools. It’s faster to load and I can search it using spotlight at any time. I have a set of bookmarks in my browser that I use to load the docs directly in my browser instead of the xcode document viewer.
Of course, you’re welcome to do what you want with your computer, but I wouldn’t recommend messing with it unless you have a good reason. If HD space is not a concern, I don’t see why you’d get rid of them. They’re not causing any harm just sitting there unused. If you’ve got to get rid of something, unused apps in the ‘Applications’ directory, and the ‘Documentation’ and ‘Examples’ folders are probably dispensable. You might get an error if you try to open a doc in Xcode that you’ve removed, but that’s not too big of a deal. Don’t remove any of the other directories, though, as they may be integral to the proper operation of Xcode and other dev tools.
