In Windows 7, when you copy a folder to a destination that contains a folder with the same name, you'll get an alert that asks you if you want to skip the folder, merge the two or cancel. In Windows 8, Microsoft took that dialog away and just does the merge without asking. Here's how to get that control back.
In most cases, you'll actually want to do the merge. If you're not careful, however, this could lead to you overwriting newer files with older copies or accidentally combining two folders you meant to keep separate. Thankfully, enabling the warning dialog is simple:
- Open an Explorer window and click the View tab. Click Folder Options.
- In the Folder Options window, click the View tab.
- Uncheck "Hide folder merge conflicts".
- Click Apply, then OK.
By default, that box is checked. Now, you'll see the old dialog warning whenever you try to copy a folder somewhere there's a folder with the same name in it. You'll also see the timestamps and creation dates for each, so you know at a glance which one is newer. Why Microsoft took the dialog away is anyone's guess, but at least it's easy to get back.
