I have a laptop but unfortunately it is full and I can unfortunately not enlarge it because I have already built in the maximum I need this other memory to load programs on it you have a possibility, the best this memory should be good for traveling and not so expensive
You mean the hard drive capacity now?
Either you swap the existing ones for larger ones or you get an external hard drive and move your files there. The programs should install on the internal.
With a lot of (sensitive) data, a NAS would also be a good idea.
I guess you're talking about a hard drive? Then take one that you can connect via USB!
But if you mean the main memory and you have already built in the maximum, then unfortunately the end of the flagpole for this laptop…
So to clarify now. Do you mean RAM or hard drive space?
If you mean hard drive space. There's really no limit to that… Unless you're using your laptop as a data grave. And for traveling, I would recommend an SSD to you, because firstly it is faster and secondly it is less sensitive to bumps and vibrations.
If you mean your RAM: Well there you can't do anything except your auto start, for example. Time to unclean. The easiest way would be to simply set up the system again and only install what you really need.
I guess your laptop will have around 8 GB of RAM that's just enough for a bit of office.
