What is a file extension?

Short answer: it's the set of letters after the period (.) in the name of a file.

Long answer: File extensions signify the file format of a file. It tells the operating system (OS) how data was stored in the file. Not all OS, require a file extension though. For instance, this is optional in Unix, but is mandatory with MS-DOS and Windows systems.

In most file formats the file type is actually defined by the contents (first bytes, file structure), but extensions are used to define the application that is used for opening the file.

Below is a detailed database of thousands of file extensions our team has compiled for you. Feel free to browse!

VP - Extension Details
Date Added: January 01, 1970
File Extension:  .VP
Description 1: File extension .VP is associated with the Xfit viewpoint file. Xfit is the map viewing and model building program in XtalView used by researchers in the structural biology field, particularly those in molecular modeling, electron microscopy and crystallography. It features builtin Fourier transforms that give users flexibility in map calculations. The program is written in C and employs a freely available XView toolkit, making it extremely portable to almost all Xwindowsbased workstation (even Intelbased Linux systems). The highly optimized Xfit enables completion of interactive contour levels and map calculations in seconds. The latest version includes solventflattening, smallprobe dot contact surfaces, phase combination, automated water addition along with other basic design features.
Description 2: File extension .VP is associated with VOCPACK lossless compressed audio. VOCPACK is a decompressor/compressor for eightbit digital sound that uses lossless algorithm. With the .VP file format, disk space is saved minus diminishing sound quality. VP files are capable of compressing signed as well as unsigned data, sampling at any rate, stereo or mono. Since it uses a nonlossy method, there is no need to strip file headers prior to compression. Although designed for use with Windows (.WAV) and SoundBlaster (.VOC) files, VOCPACK can still compress any eightbit sound as the application makes no assumptions regarding file structure.
