z/OS UNIX file system naming conventions

Guidelines: The following list describes some naming conventions you should know about when using z/OS® UNIX file system files with the z/OS UNIX FTP server:
  • The z/OS UNIX file system name is case-sensitive.
  • If a name begins with a single quotation mark, specify QUOTESOVERRIDE FALSE in FTP.DATA, or use the SITE NOQUOTESOVERRIDE command.
  • Names can contain imbedded blanks for special characters.
    Tip: Some FTP clients might truncate trailing blanks.
  • The LIST and NLST subcommands, including all client subcommands that invoke the NLST subcommand, such as MGET or MDELETE, require special handling for certain special characters. For more information, see z/OS Communications Server: IP User's Guide and Commands.
  • The START and SITE parameters have additional restrictions on the path name used with SBDATACONN. See z/OS Communications Server: IP Configuration Reference and z/OS Communications Server: IP User's Guide and Commands.
  • When specifying a z/OS UNIX FTP subcommand with a file name containing special characters, some FTP clients might:
    • Truncate trailing blanks
    • Compress multiple internal blanks
    • Interpret special characters to have special meanings
    Unique specification of the file name such as enclosing in double or single quotation mark, or escaping special characters, might be necessary to make the client send the file name to the server correctly. See your client documentation to see whether this is necessary.
