What type of file is a file?
It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary or free and may be either unpublished or open. Some file formats are designed for very particular types of data: PNG files, for example, store bitmapped images using lossless data compression.
A data structure is a specialized format for organizing and storing data. General data structure types include the array, the file, the record, the table, the tree, and so on. Any data structure is designed to organize data to suit a specific purpose so that it can be accessed and worked with in appropriate ways.
- A file that contains records or other elements that are stored in a chronological order based on account number or some other identifying data. A sequential file may be stored on a sequential access device such as magnetic tape or on a direct access device such as magnetic disk. Contrast with random file.
- A source file is a sequence of procedures and functions. An object file is a sequence of bytes organized into blocks that are understandable by the machine. When operating system defines different file structures, it also contains the code to support these file structure.

open file - Computer Definition. A file, typically a disk file, that has been made available to the application by the operating system for reading and/or writing. All files must be "opened" before they can be accessed and "closed" when no longer required.
- Portable Document Format (PDF) is a file format used to present and exchange documents reliably, independent of software, hardware, or operating system. Invented by Adobe, PDF is now an open standard maintained by the International Organization for Standardization (ISO).
- A proprietary format is a file format of a company, organization, or individual that contains data that is ordered and stored according to a particular encoding-scheme, designed by the company or organization to be secret, such that the decoding and interpretation of this stored data is easily accomplished only with
- 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)
