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.

UHA - Extension Details
Date Added: January 01, 1970
File Extension:  .UHA
Description 1: .UHA is a file extension associated with the UHarc Compressed Archive. It uses UHarc compression to compress a Windows file archive, allowing for the creation of archives much smaller than those seen in .RAR compression. The downside is: decompression takes a while. Note that UHarc archives made with UHarc 0.4 are incompatible with later versions, including UHarc 0.6 and vice versa. unUHarc found in UHarc 0.6 can be utilized for decompressing UHarc archives generated using the 0.6 version.
