1The ftplugin directory is for Vim plugin scripts that are only used for a 2specific filetype. 3 4All files ending in .vim in this directory and subdirectories will be sourced 5by Vim when it detects the filetype that matches the name of the file or 6subdirectory. 7For example, these are all loaded for the "c" filetype: 8 9 c.vim 10 c_extra.vim 11 c/settings.vim 12 13Note that the "_" in "c_extra.vim" is required to separate the filetype name 14from the following arbitrary name. 15 16The filetype plugins are only loaded when the ":filetype plugin" command has 17been used. 18 19The default filetype plugin files contain settings that 95% of the users will 20want to use. They do not contain personal preferences, like the value of 21'shiftwidth'. 22 23If you want to do additional settings, or overrule the default filetype 24plugin, you can create your own plugin file. See ":help ftplugin" in Vim. 25
