FileZilla Pro CLI maps a number of file extensions to MIME Types by default.
If you need to modify these mappings change the MIME Types setting.
The MIME type mapping is a list of MIME type to file extension pairs separated by semicolon.
To get the current MIME type mapping:
set engine.mimetype_mapping
To add a new MIME type mapping, for example, video/mp4 to mp4 extension:
set
˓→application/pdf=pdf;application/rss+xml=rss;application/x-font-ttf=ttf;application/
˓→x-shockwave-flash=swf;application/xml=xml xsl;application/xslt+xml=xslt;
˓→application/zip=zip;binary/octet-stream=bin exe;image/gif=gif;image/jpeg=jpeg jpg␣
˓→jpe;image/png=png;image/svg+xml=svg;text/css=css;text/html=html htm;text/plain=txt ␣
˓→text;video/mp4=mp4″
engine.mimetype_mapping “application/java-archive=jar;application/javascript=js;˓→application/pdf=pdf;application/rss+xml=rss;application/x-font-ttf=ttf;application/
