How to edit the content of a mod? [closed]

I was modding my minecraft when I realised that I have a lot of items and blocks that my computer couldn't handle any more mods! I realised that most of the items are useless for me! I have tried to delete some of them but as soon as I wanted to start working I realised that I have no idea how to do it!

For example in (Mrcrayfishs furniture mod) there are only two or three items that I realy want and to make the mod smaller. Is there any possible way to do it without using any special programs? If there is no such way please tell me the way you would do it?

My question is can you do it or not and how can I achieve that?

In general, to modify a computer program (and even a modification of another program, which mods are) you need to be a programmer and know source code of that program. In other words, first you need to learn to make mods, then you can learn to alter others' ones. Makers of some mods leave some things to be more easily switched around by users via "configuration files", but most do not bother.

So, no, you generally can't turn off parts of mods.
