    Sharing a Single Folder with Another User


    Hello, I am running Windows 10 Pro (21H1 - Build 19043.1052).

    I am trying to set up another user with access to a single folder and its subfolders on a new machine. I've shared this folder with that user by editing the share settings in Windows Explorer. When I log in as that user, I do see the folder that I intended to share.

    However, that user also seems to have access to the entire C: drive. When I check the share settings for the C: drive and its subfolders, it does not show that user or any other using having access other than myself.

    Can anyone advise as to what might be going on?

    When you say "when I logon as that user" it makes me think that you are saying that you are logging on locally on the machine in question.

    Am I understanding this correctly? Are you saying that the issue is that the user can see the entire C: drive when they logon locally?

    If that is correct, then note the following:

    When you set *Share permissions* in File Explorer you are setting the permissions for access from another machine over the network. This has absolutely zero impact upon what a user can access when they logon to the system locally.

    Before I go into a lot more detail, I want to make sure that I understood the situation correctly, otherwise I'll just be throwing useless info at you

    Could you just let me know if I was understanding the concern correctly? If not, please clarify the situation for me.

    Hi hsehestedt, thanks for your reply.

    Yes, this is only referring to logging on locally. And yes, the issue is that the other user can see the entire C: drive when they logon locally.

    Okay, it sounds like the "share permission" was not the right route. How then would I share the folder I want to share with the other user, and only that folder?

    Does that person have its own device (PC, tablet, smartphone)?
    My router has NAS functionality. In the router USB, I have a memory stick.
    In my home network all my devices have access to that stick. Maybe a different line of thinking?

    Okay, we're going to be getting into some more advanced topics so you may need to do a bit of reading on this.

    So, let's start be just reiterating what the share permissions do:

    When you create a share and set permissions on that, it affects absolutely nothing locally. A "share" refers to a "network share" so this sets permissions for who is able to connect to that resource over the network.

    Here is a good tutorial on the topic of sharing files and folders on the network:

    Share Files and Folders Over a Network in Windows 10

    To make files that you have on the local computer available to other users who logon to that same computer, there a few different things that you can do. The easiest thing to do is to place files that you want to make accessible to other users into the "Public Folders" in Windows. Here is a tutorial on how to do that:

    Turn On or Off Public Folder Sharing in Windows 10

    You could also set file and folder permissions to grant other users access. This is the more advanced topic that I was referencing above. Here is an article that only scratches the surface on that topic, but it's at least a good overall summary:

    https://www.dell.com/support/kbdoc/e...ons-in-windows

    One word of caution: If you are going to experiment with file and folder permissions I would suggest starting out with some test files and folders to experiment on as you can easily get to a point where you block even yourself from access to files or folders when you are experimenting. You can recover from that, but it's just safer to experiment on some test data rather than anything important.

    Thank you, hsehestedt.

    Let's take this step-by-step. First of all, I mentioned that the user (let's call her Jen) has access to the contents of the C:/ drive and its subfolders and that this is not intended. When I am logged in as myself, and I view the security settings for C:/, the "groups" that I can adjust settings for include Authenticated Users, System, Administrators, and Users. I don't see a way to edit the security settings for Jen individually. How do I do that?

    Select the file by right-clicking on it in File Explorer, select Properties, and go to the Security tab. Here you can view the current security settings. You can then click on "Edit" if you want to make any changes.

    I've done that, but I don't see a way to edit the settings for that user (Jen) individually.

    Is there a user account on that machine called Jen?

    If so, then get to the point that I noted above where the permissions are being displayed. Click on "Edit". Then click on "Add...".

    Here is an example of what I see:
    Sharing a Single Folder with Another User-image1.jpg
    You would enter the user name "Jen" and then click on "Check Names". It should find that user name. If it does, click on "OK".

    Now, check the boxes for the type of permission you want to give Jen in the "Allow" column. In the screenshot below note that I have given this user full control.

    Yes, I'm able to find that user, and I then remove all of her permissions for the C:/ drive and its subfolders. When I click apply, one thing to note - as the system attempts to set security settings for her - is that I get a series of error messages that look like the one in the file attached to this message. It only appears regarding about five .tmp and .sys files.

    In any case, when I then log in to Jen's account, she still has access to the C:/ and its subfolders.
