Common File Formats
and how to open them

There are thousands of file types found on the Internet and elsewhere these days, and figuring out what you can use when presented with the OPEN WITH dialog can be confusing.

Some formats are fairly common and will open in multiple applications, and some are completely proprietary and will only open in the software that created them. These formats vary widely in quality, image depth and resolution and some are in compressed formats. This of course is only a partial list, and as it is a "work in progress", I invite any readers who can contribute from their own experience to email me.

Below is a list of some of the most common file formats with suggestions on programs that you either have or can download to open them. Those programs which are commonly preinstalled on Aptivas as part of either the IBM or Microsoft pre-load bundle are in BOLD type. Those programs that can be downloaded as free trial shareware are shown as HYPERLINKS that will take you to some information on the software referenced.

Programs


  1. ViewPrint/VuePro - Hamrick Softwares ViewPrint is THE program for opening image and multimedia files. This will open EVERYTHING...

    Image files (.GIF, .BMP, .DIB, .RLE, .PCX, .TGA, .JPG, .CAM, .TIF, .WMF)
    Sound files (.MID, .WAV, .MCI)
    Movie files (.AVI, .MPG, .MMM, .MOV, .FLI, .FLC)
    Slide Show files (.SLI)
    Encoded files (.UUE, .UU1, .01, .MSG, .MME, .HQX)
    Zip files (.ZIP)


    The program will give you the option of associating all of the above extensions (answer YES, the software makes it easy to remove or all extensions later) -- you may never see the OPEN WITH prompt again! Supports easy converion between image formats. Four stars, must-have software.

    VIEWPRINT (shareware) Hamrick Software




  2. Paint Shop Pro - While ViewPro will OPEN everything, if it's an image Paint Shop Pro will do it ALL. A fantastic user-friendly format for creating great graphics, that will save to as well as open nearly every image file imaginable.

    PAINT SHOP PRO (shareware) JASC Software



  3. WHAM - A great semi-freeware (Download.com calls it "shareware" but the program is full featured...all the programmer asks is a "voluntary contribution" if it's useful), this program will open, edit and convert a slew of the less common audio files you may run into. The file is small, so if you're into SOUND grab WHAM (Waveform Hold and Modify)


    WHAM (freeware) DOWNLOAD.COM - WHAM



  4. Acroread - A ton of HELP files these days come in .PDF Adobe Acrobat format, plus if you surf the Web you're bound to run into some Acrobat files. Adobe has their software available as FREE (love that word) WARE.

    ACROREAD (freeware) Adobe Systems



  5. WinZip - The number ONE downloadable filetype on the Internet is .ZIP, and for good reason...who want's to sit there downloading 199 separate files to play a game or use a shareware app? The compressed archive format ties it all up in a nice neat package, and speeds download times to boot. So what's not to love? While we DO have PKUNZIP (DOS) on our Blue Diagnostics and Utilities CD, WinZip can't be beat with it's user friendly Windows interface. It's full-featured shareawre that supports those *extended evaluations* I sure love. Besides UNzipping you can ZIP files up for friends, and even convert your .ZIPs to self-extracting .EXEs for those who don't have an UNZIPper.

    WINZIP (shareware) Nico Mat, Inc.



  6. RealPlayer - The browser "plugin" from Progressive ain't just for the ears anymore. The RealAudio of yesterday has been replaced by RealPlayer, which supports those great live "streamed audio" radio broadcasts and concerts as well as the newer RealVideo. Treat your eyes AND your ears as you surf.

    REALPLAYER (freeware) Progressive Networks

Again, this is just a start, and I hope that eventually this will be a fairly comprehensive list of file type extensions. In the meantime I hope this helps, and feel free to email any suggestions.
