Find the duplicates

  • use CC cleaner, go to tools and find duplicated files

    Clean up existing data structure

    find . -type d -empty -delete
    find . -iname thumbs.db -delete
    find . -iname .ds_store -delete
    find . -iname ._* -delete
    find . -iname desktop.ini -delete
    

    To prevent mac from creating .ds_store files

    defaults write com.apple.desktopservices DSDontWriteUSBStores -bool true
    defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true
    

    This will create a file under ~/Library/Preferences/com.apple.desktopservices.plist Once you have this, the files won’t be created on network and usb stores
