Turning off sync before 2/1 cut off

Hello- I would like to turn off sync to CC prior to the 2/1 cutoff while I am transferring over/backing up files. How do I do this on all devices? I would like to delete the local copy WITHOUT having any updates mirror on CC (so that I keep all the files during backup.) Here are the issues: 

-I can't seem to turn off the sync on my phone. Do I need to delete the app? 

- I have turned off sync on my desktop (so that's fine)

-I am not able to access CC app on my MS Surface due to memory issue because CC saved a local copy of my files (just found out about this a few months ago- good times).

-I have tried to uninstall the main app and other apps (INDD, AI, PSD etc) but it won't let me because I need to update CC first, but I don't have sufficient memory. 

-What I would like to do is delete the local CC directory on my surface, have it NOT sync to the web -connected folder OR my phone app. Then I will have enough memory to do the updates. I am trying to keep the files on the CC - cloud tree until 2/1. 

-I have deleted files locally only and it is reflected in the CC cloud tree, meaning deleted on C=deleted everywhere. 

-This local copy of CC files is really messing with my scene. Both my phone and my Surface are in serious functional jeopardy because it's eating up storage. My desktop/laptop seems fine as it has a lot of memory to spare. 

Thank you in advance for any insight or help on getting rid of this local folder without consequence. I don't need these files in multiple places.
