Extension: iso
What is it? ISO-9660 CD Disk Image File
Where’s it from? Generally, ISO files are created by CD burning software such as Nero. The ISO (Intl. Standards Organization) 9660 standard specifies how to copy data, such as a set of music files, to an iso file that can be read as if it was a CD disc. ISO files can be transferred over the Internet, then burned to CD to re-recreate the original CD. An ISO file can also be mounted and used like any other drive. MagicISO can translate proprietary image file formats (such as Nero) into standard ISO files.
How do I use it? Windows: MagicISO http://www.magiciso.com/ ; Mac: Mac OS X Finder, built into Mac OS X; Linux: mount command, i. e., mount -o loop -t iso9660 filename.iso
Can I safely delete or move it? Yes.
Can it be dangerous? No
