A BZIP2 file is data compressed by exploiting structural repetition via bzip2, most often ending in `.bz2` or appearing as `.tar.bz2` when many files were tarred first, extractable through 7-Zip, WinRAR, or commands like `bunzip2` and `tar -xjf`; bzip2 favors text because it processes blocks through Burrows–Wheeler to cluster symbols, applies Move-to-Front to make them numeric and small, and then run-length encodes those recurring values.
Finally, bzip2 performs Huffman coding for entropy reduction so common symbols get very short codes, achieving major compression benefits after BWT+MTF cluster repetition, making bzip2 strong on text but slower and more memory-heavy than gzip; `.bz2` typically decompresses into one file, while `.tar.

That’s why extracting a `.tar.bz2` looks like two extractions: first you decompress to a `.tar`, then you unpack that `.tar`, unless your tool automates both; the extension tells you if you have a single compressed file or a tar archive compressed afterward, and the essential task is decompression—`.bz2` yields one restored file, while `.tar.bz2` gives an entire directory of content used for distributions, backups, or datasets, with bzip2 also helpful for creating smaller archives except for already-compressed formats which barely shrink.
What you can do with a BZIP2 file is shaped by whether you’re using, storing, or distributing it, but you almost always start by decompressing because `.bz2` isn’t directly useful; `.bz2` restores a single file, `.tar.bz2` restores entire directories, and beyond that you can compress files into `.bz2` for efficient storage, change archive types for improved compression, or incorporate `.bz2` into scripted systems where files stay compressed until processed.
To open or extract a BZIP2 file smoothly, the first thing to check is the extension, because `.bz2` is one compressed file while `.tar.bz2` (or `.tbz2`) contains a tar archive inside; on Windows the simplest method is using 7-Zip or WinRAR, where extracting a `.bz2` produces one file immediately but extracting a `.tar.bz2` often yields a `.tar` that must be extracted again unless your extractor handles both layers automatically, and tools on macOS/Linux like `bunzip2` or `tar -xjf` work reliably, with the caveat that `bunzip2` usually deletes the original `.bz2` unless told not to, and mobile apps behave similarly, with two-step extraction and occasional limitations.
To open or extract a BZIP2 file, the first task is to decompress the archive, meaning `.bz2` expands into one file you then open normally and `.tar.bz2` expands into a `.tar` that in turn unpacks into its folders, though command-line tools can do both steps together; be aware of utilities that delete the source `.bz2` automatically and of extraction errors that typically signal corruption or misnamed data, with alternate extractors like 7-Zip helping diagnose the problem.
