Autodesk 3ds Max/Small 3ds Max
3ds Max is a bulky application, and for game artists, many of the features go unused. This project is an attempt to strip down 3ds max 5 to the modeling, animating, unwrapping, and character setup minimum.
Don't delete Max's components right off. Create a backup folder somewhere and move the files into that folder. That way, if anything screws up, you can easily retrieve the files without having to reinstall max. Common sense, but some people tend to be a tad trigger happy.
First of all, what one person believes is removable may be indispensable to your workflow, so make that discretion before getting rid of those plugins. 3ds max's architecture is plugin based, so the first place I headed to was the plugins directory.
Taking a look at Plug-in Manager, these are the plugins loaded on startup and what they do.
.DLU files are Utility plugins. They are basic utilities such as the Polygon Counter, advanced utilities such as Reactor, and even legacy utilities such as Dynamics.
.DLO files are Object plugins. They create new objects. For example, if you install a "antmodel.dlo" file, it will allow you to create ants. Found on the Create Panel, in the dropdown list that says "Standard Primitives". There it will show a new section that contains the object type that the plugin provides.

.DLR files are Render plugins. They're pretty rare compared to the other types, but they're still a valid plugin. They will be found in the Render Scene window (F10) under the "Current Renderers" rollout. Click on the "Assign..." button and it will open a new window for you to choose the renderer you want to use. (by default there will only be one renderer showing, the "VUE File Renderer", since the Default Scanline is already in use)
.DLM files are Material plugins. They will be found in the Material Editor as new material types (where it says Standard, Raytrace, Multi/Sub-object, etc., there will be more)
.DLT files are Texture plugins. They will be found in the Material Editor as well, but will be as Maps, such as Brick, Speckle, Noise, etc. (usually the maps are the same name as the plugin)
