A file viewer is a utility application software on operating systems, such as Linux, macOS, or Windows. The file viewer is responsible for user access of files located on a data storage device. File viewers allow the user to open and view content [1] on a device, such as a Personal Computer (PC) or a mobile phone.
File viewer applications can be split into the following categories:
The difference in file viewers' functionality initially resulted from how proprietary file formats were licensed. While all file formats can be read freely, some software licenses allow only the licensor to create and modify files. For example, the database software DBASE used a proprietary algorithm for creating .DBF files, but Norton Commander had a built-in viewer for .DBF files. A software application such as Adobe Photoshop, LibreOffice, or Microsoft Word is required to create .PDF files, but Acrobat Reader supports viewing of .PDF files [2] .
A file format must have structural information that allows a file viewer to handle different byte orders, code pages or newline styles. In contrast, media file viewers, such as video player applications, may initially support few, if any, file formats. Media file viewers instead rely on video codecs to play various media, allowing users to expand a media file viewer's capability to read and represent media file data.
However, some media editors, such as Audacity, allow you to open most files as "raw data." [3] This has been used by artists to make glitch art. [4]
Some file viewers are filters that translate binary files into plain text (e.g., antiword). However some information may be lost depending on the translating routines.
Image viewers display graphic files on screen. Some viewers, such as IrfanView, can read multiple graphic file formats, while others, such as JPEGview only support a single format. Common image viewer features include thumbnail preview and creation, image zooming and rotation, color balance and gamma correction, resizing, etc.
A web browser is a type of file viewer that renders HTML markup into a human-friendly presentation. Although HTML is stored in plain text files, viewing an HTML file in a browser and in a text editor produces significantly different results. Web browsers may also view multimedia files such as images, videos, preformatted documents, interactive environments, 3D models, augmented reality and virtual reality applets.
In computing, a plug-in is a software component that adds a specific feature to an existing computer program. When a program supports plug-ins, it enables customization.
Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991. PDF was standardized as ISO 32000 in 2008. The last edition as ISO 32000-2:2020 was published in December 2020.
A text editor is a type of computer program that edits plain text. Such programs are sometimes known as "notepad" software. Text editors are provided with operating systems and software development packages, and can be used to change files such as configuration files, documentation files and programming language source code.
Adobe Acrobat is a family of application software and Web services developed by Adobe Inc. to view, create, manipulate, print and manage Portable Document Format (PDF) files.
dBase was one of the first database management systems for microcomputers and the most successful in its day. The dBase system included the core database engine, a query system, a forms engine, and a programming language that tied all of these components together.
A binary file is a computer file that is not a text file. The term "binary file" is often used as a term meaning "non-text file". Many binary file formats contain parts that can be interpreted as text; for example, some computer document files containing formatted text, such as older Microsoft Word document files, contain the text of the document but also contain formatting information in binary form.
IrfanView is an image viewer, editor, organiser and converter program for Microsoft Windows. It can also play video and audio files, and has some image creation and painting capabilities. IrfanView is free for non-commercial use; commercial use requires paid registration. It is noted for its small size, speed, ease of use, and ability to handle a wide variety of graphic file formats. It was first released in 1996.
A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program. Some programs are more suitable for artistic work while others are better for technical drawings. Another important factor is the application's support of various vector and bitmap image formats for import and export.
The Extensible Metadata Platform (XMP) is an ISO standard, originally created by Adobe Systems Inc., for the creation, processing and interchange of standardized and custom metadata for digital documents and data sets.
Open XML Paper Specification is an open specification for a page description language and a fixed-document format. Microsoft developed it as the XML Paper Specification (XPS). In June 2009, Ecma International adopted it as international standard ECMA-388.
A camera raw image file contains unprocessed or minimally processed data from the image sensor of either a digital camera, a motion picture film scanner, or other image scanner. Raw files are so named because they are not yet processed, and contain large amounts of potentially redundant data. Normally, the image is processed by a raw converter, in a wide-gamut internal color space where precise adjustments can be made before conversion to a viewable file format such as JPEG or PNG for storage, printing, or further manipulation. There are dozens of raw formats in use by different manufacturers of digital image capture equipment.
Quick View is a file viewer in Windows 95, Windows 98 and Windows NT 4.0 operating systems. The viewer can be used to view practically any file.
The following is a comparison of e-book formats used to create and publish e-books.
Solid PDF Tools is a document reconstruction software product which allows users to convert PDFs into editable documents and create PDFs from a variety of file sources. The same technology used in the software's Solid Framework SDK is licensed by Adobe for Acrobat X
Recovery Toolbox is a family of tools and online services for recovering corrupted files, file formats, and recovering passwords for various programs.
