Hi, When I click the Storage I Can't found "Manage"... Its not appears...

Check if safe mode helps.

How to use safe mode on your Mac - Apple Support

Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.

See if this helps.

> (hold option/alt) > System Information… >

Then in the window menu you should find "Storage Management ⌘U".

What version of macOS?
