File Formats in Computer

"In a computer, a file format is the layout of a file in terms of how the data within the file is organized. A particular file format is often indicated as part of a file's name by a file name extension (suffix). Conventionally, the extension is separated by a period from the name and contains three or four letters that identify the format. ----- FMUSER"


The file format is the structure of a file that tells a program how to display its contents. 

#File Formats in Computer

For example, a Microsoft Word document saved in the .DOC file format is best viewed in Microsoft Word. Even if another program can open the file, it may not have all the features needed to display the document correctly.

Programs that are compatible with a file format may be able to give an overview of a file but may not be able to display all the files features. Also, with some programs opening a file format that is not supported may give you garbage.

Application programs must be able to recognize and possibly access data within the file. Sometimes a program may not care whether the file has the appropriate extension name because it can examine the bits in the file to see whether the format (layout) is one it recognizes. Other times, the end user must specify what program should be used to open and work with file.

There are as many different file formats as there are different programs to process the files. A few of the more common file formats are:
●Word documents (.doc)
●Web text pages (.htm or .html)
●Web page images (.gif and .jpg)
●Adobe Postcript files (.ps)
●Adobe Acrobat files (.pdf)
●Executable programs (.exe)
●Multimedia files (.mp3 and others)
