Support for Long File Names

Like Windows®, Z and I Emulator for Windows supports long file names. You can give any name (up to 255 characters) to a file; you are not limited to eight characters with a three-character extension. You can use spaces in the file name, but not the symbols /, \, :, *, ?, “, <, >, or |. In addition, the tilde (~) character should not be used in CMS or MVS host file names.
