A Guide to File Extensions You will find attached a list of the extensions you might find on your pc, floppy or the internet. The list includes the extension, description, whether it's text, and the likely programs to use to view the contents. Because I included the internet there are unix, mac, … files included - where possible I've include PC programs which will read them. Some of the programs will only read or write or only accept certain variants of the file so even though a program is listed it doesn't mean it will read your particular version of the file. I have done my best to keep this accurate but this is supplied on a all care but no responsibility basis.

Saturday, 15 June 2002 Copyright Wayne Corbin (1997 - 2002) Page 9 of 77 Any additional information or Corrections happily received := [email protected] Extension Description Ascii/Bin Viewer BIF Binary Information Files - Created by Handmade Ascii Alchemy Software, Inc. There are quite a few programs which produce image files which contain just pixel data. These image files do not have a header and hence do not include enough information to read them. BIF files are a method which can be used to read these images. BIF files can also be created to allow images to be read by software which expects images to be just . Since required information, such as the height and width of the image, are not present in these files - you must supply it. .bif For ASCII file describing image. .raw For actual image data. (See RAW File Extension) The first line contains the letters BIF, which identifies the file as a BIF file. Each of the rest of the lines in the BIF file consist of an information followed by the information. Tags

Tag Description filename The name of the file containing the binary data. width The width of the image data, in pixels. height The height of the image data, in pixels. planes The number of planes of image data (1, 2, 3, or 4). A 1 plane image is assumed to be gray-scale, a 2 plane image is a gray-scale image with an alpha channel, a 3 plane image is an RGB image, and a 4 plane image is an RGB image with an alpha channel. header The size of the header, in bytes. This many bytes are skipped when reading the file. leftpadding The number of bytes to remove from the beginning of each scan line. rightpadding The number of bytes to remove from the end of each scan line. order The order of the pixels. For 2 channels either ga or ag(g=gray, a=alpha). For 3 channel images, this can be any sequence of r, g, and b: rgb, rbg, grb, gbr, brg, or bgr (r=red, g=green, b=blue). For 4 channel images, this can be any sequence of a, r, g, and b (a=alpha). The defaults are g, ga, rgb, and rgba, depending on the number of planes. interleave The type of interleaving of the pixel data: 0: No interleave RGBRGBRGBRGBRGBRGB... 1: Line interleave RRR..GGG..BBB..RRR..GGG..BBB.. 2: Plane interleave RRRRRR...GGGGGG...BBBBBB... The default is 0, no interleave. upsidedown The presence of this tag indicates that the data in the file is recorded from the bottom of the screen up to the top of the screen. Comments Lines beginning with a # are treated as comments. Palette files If the binary file has a palette available.

Example

Developers can add their own features and functions to the file while remaining compatible with other applications. * allows three compression options - JPEG compression, uncompressed and single-colour compression. * supports calibrated and uncalibrated versions of RGB, Photo YCC and monochrome colour space definitions. * supports non-image information including: file source, owner, picture description, camera/scanner description, camera/scanner settings for each picture, ... * supports Image views stored as separate files, and linked electronically to the original file. This means a different version of an image can be very small by storing only an image view or a link to the original image.

JPEG Joint Photographics Experts Group Bin Alchemy, cjpeg, DeBabelizer, JPEG compression discards "extra" data; that is; djpeg, imagemagick, Internet information beyond what the human eye can see. Explorer, Lview Pro, MS Word, Because it discards data; the JPEG algorithm is referred Paintshop, PhotoShop, Picture to as "lossy." This means that once an image has been Publisher, xv compressed and then decompressed; it will not be identical to the original image. In most cases; the difference between the original and compressed version of the image is indistinguishable. One advantage of JPEG compression is that you can select the quality when compressing the image. The lower the quality; the smaller the image but the more different it will appear than the original. Since JPEG compression was designed for use with continuous tone images (such as those produced by a scanner or digitizer), poor results can be expected when compressing line drawings. NOTE: JPEG refers to compression algorithm not the storage format so it is possible to have 2 images stored in different ways. JFIF - JIF is the JPEG standard for the File storage format. (Use JIF to store images where possible. You should also check stored images to confirm the data loss is acceptable before you remove the original image.) (8, 24 bit colour)

Note that this format is not the same as IBM Picture Maker. Cubicomp PictureMaker does not work with images which are not of the exact size. If either the X or Y dimension is larger than 512 or 488, respectively, that dimension will be truncated. If either dimension is smaller than 512 or 488, the image will be padded on the right-hand side or bottom, as necessary, with black. PictureMaker images have either three or four separate files per image: a red file, a green file, a blue file, and an optional alpha channel file. The File formats are .r8 (Red channel image data), .g8 (Green channel image data), .b8 (Blue channel image data) and optionally .a8 (Alpha channel image data). (See G8, B8, A8 File Extensions)

REG An export of All or part of the Registration database Ascii Notepad, Regedit file; used by Windows 95, ... A branch of or the entire Registry can be restored by importing a .REG file that was created by exporting the Registry. In rare circumstances when the Registry is badly corrupted, you can start the computer using the Windows 95 startup disk. Then you can use the real- mode REGEDIT.EXE utility on the startup disk to import a .REG file. In this case, the following command syntax can be used at the command prompt. regedit [/L:system] [/R:user] file1.reg, file1a.reg... regedit [/L:system] [/R:user] /e file3.reg [regkey] regedit [/L:system] [/R:user] /c file2.reg

Parameter Description /L:system Specifies the location of SYSTEM.DAT. /R:user Specifies the location of USER.DAT. file1.reg Specifies one or more .REG files to import into the Registry. /e file3.reg Specifies the filename to which the Registry should be exported. Regkey Optionally, specifies the starting Registry key from which to export a portion of the Registry.

Like bitmap hot spots, hypergraphics let you use graphics instead of text to create links to other topics, display information in pop-up windows, and execute Help macros. The difference between bitmap hot spots and hypergraphics is that, using hypergraphics, you can define multiple hot spots within the same picture to perform all these operations. In this way, creating hypergraphics extends the usefulness of graphics in your Help file. Conceptually, a hypergraphic consists of two layers: * A Windows bitmap or metafile * One or more rectangular hot spots superimposed on the bitmap

If you selected the option to install the graphics tools when you install MS Help Author, Hotspot Editor will be included. (see MRB file extension)
