I know proxy object are objects that will replace other objects like low-res objects will replace high res objects. I want to know the point of using low res objects like 3d main characters.
i saw animations of low res models, but gain i want to know point of this. is it like beta test like preview of real models?
Yes, the proxy is a low res mesh that replaces the high mesh, it’s used when you work on animation characters with high res, they are usually hard to animate with the lag caused by alot high res models, so you use a proxy mesh instead to make your working more smoothly no lags.

With a large project using Blender, one can access different assets, objects or rigged characters, from different files by linking them to your working file. People can work on different parts of project as you assemble it. Working file can be kept small by not having every items copied there and not having to update them every time details get changed!
Problem with linking is that linked object will only show up at exact wold space location where if was placed in parent file and it can not be moved or edited. Proxy solves this problem. When linked object is made proxy, you can move it around, place them where you want it. When rigged characters are made proxy, you can pose it in your working file. Proxy is still linked to its parent file so that when detail gets updated it will automatically update in your working file.
