although some people know the meaning of files and the extension names that they go by this does not mean everyone does so ive compiled this user guide to help you to get to grips with the different types. *

(midi or .mid) this is the most commonly used format for polyphonic ringtones used in most mobiles today ,its a high quality sound small in disk size but is purely instrumental & cannot play voice sounds *

(amr or .amr) this is similar to mp3 but of a poorer quality but is voice/music, its mainly used for compressing speach & not music but can be used for either *

(mp3 or .mp3) this is in the middle range of the audio formats with high quality voice/music playback & medium disk size, the higher the bitrate (notes per millisecond) the better the quality but also creates a bigger file size *

(wave or .wav) this is in the top tier of the voice/music formats ,it creates near cd quality sound files but only just smaller in file size than the original cd , you can make the file size smaller or bigger by choosing different options, wavs are mainly used on pcs or as small noise clips like the windows startup jingle that plays when you switch your pc on *

there are many other file formats used to create sound files but these are the main ones.......:next page: image file formats >>>> *

image formats: (jpeg or .jpg) this format is the most widely used of all the formats & the one which nearly all camera phones use, its a high quality format (depending on the camera used to take the images) & can be made very small in file size but this means reducing quality *

(gif or .gif) this is the only format that can be used for animated images, its a good format for bold plain colours & wording but not very good for photo images but offers small file sizes in exchange for quality & when used in a animation program can create brilliant moving images *

(png or .png) this is a pc file format which offers the best quality for most images but has huge file sizes & one which i store most of my artwork in due to the high quality that it saves in ,some newer nokias/samsungs use this format as well as the others above for wallpapers or savers *
toddster 7/29/2006 - 10:04:03
(tif or .tif) this format is mainly used in very expensive cameras instead of jpg and most pcs use this format to ,it has super high quality but even bigger file sizes than png *

(bitmap or .bmp) this is probably the best format to save image files into when using a pc, it offers perfect quailty but massive file sizes & is rarely used by most people due to the huge file sizes it produces......:next page: video formats >>>>> *
toddster 7/30/2006 - 8:40:59
:video formats: (3gp or .3gp) this is a low quality small file size format of video which is used mainly in camera video phones & some digital cameras. *
toddster 7/30/2006 - 8:48:30
(mpeg-4 or mp4) a very high quality file format which will be the main file format used eventualy, most newer mobiles now play this format aswell as 3gp & the next range of mobiles will also record in this format too . *
toddster 7/30/2006 - 8:57:36
(wma/wmv) a windows based file format high in quality & virtualy identical to mpeg-4 files, usualy found on streaming websites & can only be played using windows media player or similar player. *
toddster 7/30/2006 - 9:16:20
(avi or .avi) the first video file that microsoft created & used on windows, its poorer in quality than mpegs & used in video cds. *
toddster 7/30/2006 - 9:20:11
(mpeg or .mpg) is the most commonly used format on the web, offering reasonable quality video & small file sizes compared to other formats. *
