when i open finder i search L. I found library before using this way and know i cant find it
Are you looking for your user Library? In Finder, hold down the option key and then click on the "Go" menu - your user Library will be listed. There's also a way, via Terminal, to permanently 'unhide' your user Library if you wish.
Hidden by default. Launch Terminal, copy/paste the following:
chflags nohidden ~/Library
Hit enter. Your Library folder will now be visible in Finder.
