Permission denial on network drive folder w/ full control for everyone

My goal is to setup my current computer and an older laptop to run together over a home network (specifically, to run flight simulator x steam edition on my newer "host" and use the older "client" to run certain add-ons). I've troubleshot my way through a load of problems and it's finally boiled down to this problem I can't seem to resolve.

Here’s as much info as I can think to share about the setup:
• Both host and client are connected by ethernet cables to a router, so no wireless issues as I have read wireless can cause problems for the applications I'm using.
• Both computers are running updated windows 10 os.
• My firewall is disabled on both computers for private networks (which includes my home network).
• The hard drives are all shared between them with full control for each shared device for "Everyone".
• UAC is turned off on both.

Each computer has a C and D drive, with system files on the C drive of each. I don't seem to have a problem navigating or accessing folders or files on either D drive from the remote computer, but I do have a problem accessing certain folders on the C drive of each. Specifically, the application I'm running needs read/write abilities in c:\user\myusername\documents and c:\user\myusername\appdata\roaming\microsoft\fsx. The problem is that for either computer I cannot get past the myusername (for my host it's "Admon", for the client it's "Andrew", not that it matters). I get the "Windows cannot access \\... You do not have permission to access..."

Each computer's drive has their respective root c and d drives shared for "everyone" with full control. I've also checked the security tabs to ensure everyone is listed with full control.

I'm at a loss of what to do next. Every troubleshooter I've found online has gotten me to this point but I still cannot access the user's folders (the users are both admins on their respective platforms).

Thanks in advance for anyone willing to share their insights or ask questions.

Welcome to the forum. The answer is very simple you are setting share permissions but that does not give you file /folder permission that is controlled by NTFS permissions even if your on a pc you cant normally get to other users desktop / profile etc. You need to add the other user to the folder permissions

Thank you for the welcome. Would you mind elaborating on a process for that? I thought going into the c drive's properties/security/advanced, selecting "everyone" and checking the "replace all child object permissions..." might fix it, but I'm not exactly sure how to do what you recommended.

Thanks

If your not careful you will mess up your pc giving everyone access to the drive is crazy your asking for people to hack you and ransomware. You can share things by using the $ before the name like $myfiles that makes it hidden and only admin can connect. You only give permission to the folder by adding the other user dont change any other settings system must have full control for a lot of folders or windows wont work. see how to set permissions Windows 10 And 8.1 File And Folder Permissions (ACL) Tutorial Video - YouTube
