• Junk files created by macOS (or Finder)...
  • You can disable MDS on a specific volume, but you need to create a hidden file to do it

    $ sudo touch /Volumes/{drive name}/.metadata_never_index
    

• more details
  • .DS_Store – The name of a file in the Apple OS X operating system for storing custom attributes of a folder such as the position of icons or the choice of a background image (Read more)
  • .Spotlight-V100 – This file holds information to speed up the 'Spotlight Search' feature. Deleting would simply force this information to be re-indexed if you performed another Spotlight Search for an item in this folder.
  • .apDisk – This file holds information about shared folders and can be safely removed as it will be automatically re-created if Apple needs it.
  • .VolumeIcon.icns – This file is used to store the icon of the volume (USB device) if the volume uses a custom icon and not the default icon. If you want the device to continue using this default icon, or if the folder/device you want to clean contains an application, you might want to keep this file in your system. As a side note, if you wanted to create a custom icon for your device you could create/download an .icns file and rename it .VolumeIcon.icns and place in your folder/device.
  • .fseventsd – This file is used as a buffer for the File System Events daemon. If you are using a program that is monitoring this folder/device, this file might be used to store temporary data.
  • .Trash & .Trashes – These folders are used to hold deleted items the same way that the 'Trash' icon from the dock works. If you don't need this feature on your folder/device, you can clean this folder to save space.
  • .TemporaryItems – This file is used by the OS to hold temporary data when files are being copied/moved/appended. If you are running any programs that are accessing the folder/device you want to clean, and you aren't copying or moving any files, then this file can simply hold old data for caching.
