We'll need more information on what the problem is:

https://www.zotero.org/support/reporting_problems

Sorry but we really need a longer description of what's going on -- just like you'd like us to give you step-by-step instructions, we need to understand step by step what you're seeing to give you the right information.

You can just drag files from your operating system to Zotero Standalone, but I'm not sure that's what you want.
You'll really get much better answers if you spend some time describing what exactly is going on.
How are you using Zotero? Which version? When you say "files that are missing" -- where are they missing from? How can you tell they are missing? When you want to upload files to Zotero -- what exactly do you mean by that: attaching files to existing Zotero items? re-creating Zotero items? etc. etc. A good description that allows us to help will be at least twice as long as this post.

when you say "they show to be in a zotero storage" I assume you're referring to a folder location? What is the exact location of that folder?
And you have had Zotero on that computer before?

yes

on my computer:

C:\Users\EFutrell\Zotero\storage

In the folder C:\Users\EFutrell\Zotero do you have a file called zotero.sqlite? What's its size?

OK, and when you got to Zotero and open the Preferences under "Edit" then go to Advanced --> Files and Folders and click on "Show Data Directory", what folder does that open?

Also how many items (more or less, doesn't need to be at all precise) would you expect in your Zotero database? A size of 1,804KB suggest a pretty small library.

I think it's a better idea to try to restore your Zotero library (and if you want to do that, please answer my last question above), but if you really do want to start from scratch:

To get PDFs into Zotero, yes, you'll need to drag&drop them or use "Store copy of file" under the green + sign.

Note that both allow you to select multiple files at once.

now on my library the one which is company's we have our group library by the name of coimmune IP now its the same file that we are trying to retrieve. but we are doing a test folder on my account because we are scared to loose the files. so now on our library the documents are in organized order but when i upload it from computer saved files to another folder that i created it doesnt show up as organized

Sorry, I'm completely lost now. I do not understand how the group figures in here.

As for the questions:
> copy all that folder on another folder in zotero
I'm afraid I don't understand this

and
> copy all the files from computer with one click on zotero

not sure what "all files" means -- but in general, there is no one click solution if you have a folder with hierarchies and you want to import all files in the folder to Zotero that'll take multiple operations. Depending on the details, using a saved search in your operating system may be a way to, e.g., get all PDFs from a folder hierarchy into a single folder from which you can select all + drag&drop

i am lost too

so on show data directory it shows folders and zotero.sqlite
and zotero.sqlite.1 and zotero.sqlite.76 ( these two show pdf icon next to them) and zotero.sqlite-journal

or maybe more in zotero database

yes same
