Turn it on only when you need it
There are times you need to see hidden files β tracking down a program's configuration file, or checking a backup folder, for example. Once you're done with that task, turning the setting back off helps keep your file browser uncluttered for everyday use.
A quick tip while you're at it
The same View settings menu that shows hidden files also lets you show file extensions. Turning both on together makes it much easier to identify exactly what a file is and where it came from, especially when troubleshooting.
Frequently Asked Questions
What happens if I accidentally delete a hidden file?
Deleting a hidden system file can cause a program or the operating system to misbehave, so it's safest to only delete files whose purpose you're certain of.
Can I also show file extensions at the same time?
Yes β in that same View settings menu, turning on the 'File name extensions' option lets you see file types more clearly alongside hidden files.
