There are two very different ways to set up file sharing in Windows 10: through ‘Windows HomeGroups’ and or through File Explorer. Which one you should use largely depends on how much control you want over what is shared.
HomeGroups only share all of your files by a certain type (such as photos or documents), while the File Explorer method allows you to create a shared folder for Windows 10 through your Network and Sharing Settings.
Step 1: Find the file you want to share
Open File Explorer and navigate to the file or file you want to share. You can share any file, although you cannot share any file with any application. (For example, you cannot share DLL files with Facebook – I have tried). Please select the file you want to share by clicking on it.
While there’s a one-time Share button in File Explorer, it’s hidden inside the Share menu. Click Share to open the Share menu. Depending on the file type you have chosen, different Share menu options will be available to you. For example, if you have selected a folder, not a file, the Share button will be greyed out, and the Zip button will be available. From the Share menu, you can also compress, burn, print, and fax files, as well as modify Network Share options.
Share buttons have the same three-dot-circle icon as Windows 8. Click the Share button to open the Share sidebar.
Step 4: Select the program you want to share with
In the sharing sidebar, you’ll see a list of apps where you can share your files. Again, depending on the type of file you’re trying to share, some apps might not show up. Facebook and Twitter won’t show up if you’re trying to share a zipped folder, but Mail will.
Step 5: Configure your Sharing preferences.
By default, the Sharing sidebar shows the apps you share most often – to change this and other Sharing Options, go to the Settings menu, click System, and open the Share tab. Here you can turn on and off the list of frequently used apps, choose how many items appear in that list, and enable sharing with certain apps.
While sharing directly from File Explorer is undoubtedly handy, there doesn’t seem to be a way to share other media types (e.g., a link) that doesn’t appear in File Explorer. Because there’s no more Charms bar, you can’t just tap Share charm whenever you come across a website you want to share with Facebook. Hopefully, Microsoft will develop a solution to this problem before the final version of Windows 10 drops.
