It's easy to display it. On the View tab, check the box next to "Hidden items" to display hidden system files and folders, and check the box next to "File name extensions" to display those.
Hide files and folders
To hide those files and folders again, simply uncheck the "Hidden items" checkbox again.
Want to hide more files and folders? Simply select them, then click "Hide selected items" near the right edge of the Ribbon's View tab. Then, when the "Hidden items" checkbox is unchecked, you won't be able to see those items.
Change icon sizes
While you're on the View tab, you can change the size of the icons that represent files and folders. You'll find these options just to the right of the icons for turning panes on and off.
By default, when you open a folder, File Explorer shows three columns of information about each file in the folder: date modified, type and size. But you can add columns that show other information, such as the date it was created, its author, tags and more. Just go to the View tab's "Current view" group and click the down arrow next to "Add columns" to add them.
These are your options for adding columns of information about each file in File Explorer.Click to view larger image.
Near the "Add columns" choice, you get several options to change how those columns display, including how you sort them, group them and make them all fit on a single screen.
Use the invert selection feature
On the far-right side of the Home tab, there is a group of commands called Select. The "Select all" option selects all files in a folder, and "Select none" deselects them. The third option, "Invert selection," is confusingly named but surprisingly useful.
Let's say that you've hand-selected certain files in a folder by holding down the Ctrl key while clicking them. Once you've selected them, you can perform a task on them all -- delete them or copy them or move them somewhere else, for example.
Now imagine that you've got 30 files in a folder, and you want to delete 26 of them. The obvious way to do it would be to tediously hand-select 26 of them one by one and then delete them. Here's where "Invert selection" comes to your rescue.
Select the four that you don't want to delete, and then click "Invert selection." Now all the files that you selected are no longer selected, and the other 26 are selected. You've inverted the selection, and you can now mass-delete the 26 files.
