### 5.1.1 Checking output type and file extension

When you set up a conversion project (see §3.3 Creating a Mif2Go conversion project), you use the Mif2Go Choose Project dialog to specify the output type. Mif2Go produces a new project configuration file for you that contains the correct setting for the output type you selected. Do not change this setting.

Table 5-1 shows the name of the project configuration file for each output type, and the default extension for output files. You can change the setting for the output file extension, for all output types except DITA and WinHelp. Additional settings may be required as appropriate for each output type. For example, if you change the value of HTMLSuffix or XMLSuffix, you must also change the value of FileSuffix to match, or links between split files might fail; see:

§13.2.4 Specifying a different output file extension

§19.6.2 Specifying a file extension for interfile links

Table 5-1 Output types, configuration files, and file extensions

Output category | Output type | Project configuration file | Output file extension setting | Ref.
HTML-based Help | Eclipse Help | _m2eclipse.ini | HTMLSuffix = .htm | 12
Microsoft HTML Help | _m2htmlhelp.ini | HTMLSuffix = .htm | 9
JavaHelp | _m2javahelp.ini | HTMLSuffix = .htm | 11
OmniHelp | _m2omnihelp.ini | HTMLSuffix = .htm | 10
Oracle Help for Java | _m2oraclehelp.ini | HTMLSuffix = .htm | 11
HTML | Standard HTML | _m2html.ini | HTMLSuffix = .htm | 13
XHTML | _m2xhtml.ini | HTMLSuffix = .htm | 13
XML | DITA XML | _m2dita.ini | XMLSuffix = .dita | 15
Docbook XML | _m2docbook.ini | XMLSuffix = .xml | 17
Generic XML | _m2xml.ini | XMLSuffix = .xml | 14
RTF | WinHelp | _m2winhelp.ini | .rtf (not settable) | 8
Print RTF | _m2rtf.ini | WordSuffix = .rtf | 6
Intermediate | ASCII DCL | _m2dcl.ini | HTMLSuffix = .dcl | 38
| FrameMaker MIF | _m2mif.ini | MIFSuffix = .mif | 38

You can also use the Export dialog to change the file extension, just before running a conversion (see §3.7 Choosing final conversion options). When you do, Mif2Go writes the new extension to the configuration file.
