If you have personal files and folders that you don't want to be visible to all users of your PC or you want to hide them so that they do not get deleted accidentally then here is the step by step guide for you.
Hiding Files and Folders Using File Explorer
Step 1: Open the Windows File Explorer.
Step 2: Navigate to the file or folder that you want to hide.
Step 3: Right-click the item (file or folder) and then click on Properties.
Step 4: Check the hidden option in attributes section.
Step 5: Click Apply to activate the new setting.
Step 6: If you are hiding a folder with files and sub folders, make sure to check the "Apply changes to this folder, sub-folders, and files" option.
Step 7: Click OK to close the settings and another time OK to finish.
Once you are done with these steps, the file or folder will not be visible anymore. Windows 10 doesn't show the hidden files and folders in Explorer or file menus by default. If you need Windows 10 to show your hidden files, open the file explorer, go to view and check the "Hidden items" box.
