Reconnect my data?

Following situation:

My data is all under, OS (C. / Myusername. But I want to see all these files when I start my laptop and not have to go to OS (C. Etc.).

How can I make all of this the default. Do you understand what i mean?

My laptop is, so to speak, completely "new" or emptied with OS (C. I have all my data. I want it to be so that my laptop doesn't look empty but all of this data is normal on it.

I honestly don't understand what you mean. Your data is now under C: \ users \ userxy \ documents or pictures, videos, etc.

If you only have one hard drive, that's perfectly normal. If you want to have the whole thing "at hand" quickly, then simply create the appropriate shortcuts on your desktop.

Yes, the first paragraph is correct. Did you understand correctly? But if you look at the question I asked before this one, the problem becomes clear to you.

Do I have to link everything individually or how?

There can be tens of thousands of files and folders in your home directory. If you want shortcuts on the desktop, you have to add them there individually, because it is not known what you want shortcuts to. Or have I misunderstood?

I already understand how you mean that. But look at the 2 questions in front of this one. There I say that I have had this laptop for a while and that everything was fine. Then today when starting up everything "reset" itself. I'm still logged in with my Microsoft Acc but all my data is no longer where it should be. Under "Documents" is "no files" as well as "Photos, Videos, Desktop, etc." But all the data is there where I described it. Now I want the data to return to their place. It can't be that something like that happens
