# extmap.conf(5)

Configuration file used by afpd to specify file name extension mappings

## Name

extmap.conf — Configuration file used by afpd to specify file name extension mappings

## Description

**extmap.conf** is the configuration file used by **afpd** to specify file name extension mappings.

The configuration lines are composed like:

-

  ```
  .extension [ type [ creator ] ]
  ```

Any line beginning with a hash (“#”) character is ignored. The leading-dot lines specify file name extension mappings. The extension ‘.’ sets the default creator and type for otherwise untyped Unix files.

## Examples

### Example: Extension is jpg, type is “JPEG”, creator is “ogle”

-

  ```
  .jpg "JPEG" "ogle"
  ```

### Example: Extension is lzh, type is “LHA”, creator is not defined

-

  ```
  .lzh "LHA"
  ```
