An archiver program originally developed for the MS-DOS environment, that uses LZHUF compression techniques to achieve maximum compression. See also Arc, Archive, LhA, and Zoo.

n. A freeware file-compression utility program developed by Haruyasu Yoshizaki and introduced in 1988. With LHARC, the contents of one or more files can be compressed into a singular, smaller file, with the extension .lha. A copy of the program is required to uncompress these files. LHARC can also embed a small program with the compressed information and save everything in a single file, called a self-extracting archive, with an .exe extension. As a result, the recipient of the compressed file does not need a separate utility program to uncompress the file. See also freeware, PKZIP, utility program.
