Incredibly hard to find a straight answer! 1 licence on two computers.. sync folder issue

Plain and simple; I'm on a Teams plan. I got Two work PC's. I shoot video, another guy with his own license edit. We need a shared folder. I have limited space. I want this kind of set up:

1st laptop (main use, but with limited space on dirve) 

2nd desktop (only used for storage with lots of GB/TB available).

The editor have used up his 1TB, on his machine, different sync folder and licence.

I do NOT want to use and external drive on my 1st laptop, hence the reason for 2nd desktop as storage unit!

The "Creative Cloud Files" shared folder is a big issue for many. Such a big fail from Adobe really, 1TB "cloud" [edited by moderator] haha..

Please at least provide some clarity to the several questions listed below.

1) I will NOT use any actually useful Adobe app on my 2nd desktop (Premier, PS etc), this is only as a storage unit that is always internet connected but idle/a sleep.. Does the CC desktop app count as  "an app in use" and is this only "singed-in"? 

Adobe says: "You can activate and remain signed in to the app(s) on up to two computers."

To sync files between the 1st and 2nd device, does it mean I have to sing in and out all the time? If so, where is the "CLOUD" function??

2) What if I want to use a useful app, say PS, on a different 3rd PC and will not be running apps at the same time appart from my 2nd storage unit. Will this cause me to sign out on my 1st main laptop?

This is the reason for the question abt "app in use" vs. "licence in use".

3) many ppl want to dump files on the shared folder, and then delete on the "main" device (1st main laptop in my case).

Is it not possible to only keep files on the other 2nd device??

Sure it works Adobe says. Practically impossible I say. Pause sync is not it. Constantly move files to a non-sync folder on 2nd device is such a hassle, and other collab /invited users (different licence) would loose accsess!

4)  Is it even possible to have a work-around where 2nd desktop (strictly as storage unit, signed-in, only running CC for sync, no "apps" like PS) have two sync folders, and on my 1st main paltop I only sync a sub-folder. 

This would be useful for my invited users (different licence) since they could then move the files from that sub-folder to the root "Creative Cloud Files" shared folder.

Been all over posts here, FAQ, how to's on Adobe for hours.. and this does not help at all: https://helpx.adobe.com/download-install/using/install-apps-number-of-computers.html
