What is an LHA file?
The LHA format (originally known as LHarc) is a lossless compressed archive container developed by Haruyasu Yoshizaki in 1988. It implements the Lempel-Ziv-Huffman (LZH) algorithm, a hybrid compression method combining LZ77 sliding-window dictionary compression with static Huffman coding for entropy encoding. Historically significant on Amiga and MS-DOS platforms and remaining a standard in Japanese software distribution, the format utilizes a header structure containing file attributes, timestamps, and a 16-bit Cyclic Redundancy Check (CRC-16) to verify data integrity across compressed volumes.
How to open an LHA file
Native support for the LHA architecture is generally absent in modern operating system kernels such as Windows 10/11 or macOS Ventura. To access the contents, users must employ third-party extraction utilities capable of parsing the LZH algorithm. 7-Zip is the recommended solution for Windows environments; macOS users should utilize The Unarchiver for extraction. On Linux distributions, the lha or lzh command-line utilities can be installed via package managers like APT or RPM to handle decompression.

What is a TAR file?
The TAR (Tape Archive) format is a file format standardized by POSIX.1-1988 and later POSIX.1-2001 (pax), originally developed for writing data to sequential I/O devices like magnetic tape drives. Unlike modern archive formats, TAR is purely a container format that concatenates multiple files into a single archive without native compression, preserving file system attributes such as user/group permissions, dates, and directory structures. It is frequently paired with compression utilities like Gzip or Bzip2 in Unix-like environments.
How to open a TAR file
Most Unix-based systems (Linux, macOS, BSD) include native support via the GNU Tar command-line utility. Windows does not natively support TAR extraction in versions prior to Windows 10 (Build 17063), requiring third-party tools. For cross-platform compatibility, 7-Zip and WinRAR are standard utilities for inspecting and extracting TAR containers.
