==Dealing with compressed files==
Compressed dump files are significantly compressed, thus after being decompressed will take up '''large''' amounts of drive space.  A large list of decompression programs are described in [[comparison of file archivers]]. The following  programs in particular can be used to decompress bzip2, [[.bz2]], [[.zip]], and [[.7z]] files.

;[[Microsoft Windows|Windows]]
Beginning with [[Windows XP]], a basic decompression program enables decompression of zip files.<ref>{{cite web|title=Benchmarked: What's the Best File Compression Format?|url=http://www.howtogeek.com/200698/benchmarked-whats-the-best-file-compression-format/|website=How To Geek|publisher=How-To Geek, LLC|accessdate=18 January 2017}}</ref><ref>{{cite web|title=Zip and unzip files|url=https://support.microsoft.com/en-us/help/14200/windows-compress-uncompress-zip-files|website=Microsoft|publisher=Microsoft|accessdate=18 January 2017}}</ref> Among others, the following can be used to decompress bzip2 files.
* [https://sourceware.org/pub/bzip2/v102/bzip2-102-x86-win32.exe bzip2 (command-line)] (from [https://www.sourceware.org/bzip2/ here]) is available for free under a BSD license.
* [[7-Zip]] is available for free under an [[GNU Lesser General Public License|LGPL]] license.
* [[WinRAR]]
* [[WinZip]]

;[[Macintosh]] (Mac)
* [[macOS]] ships with the command-line bzip2 tool.

;GNU/[[Linux]]
* Most GNU/Linux distributions ship with the command-line bzip2 tool.

;[[Berkeley Software Distribution]] (BSD)
* Some BSD systems ship with the command-line bzip2 tool as part of the operating system. Others, such as [[OpenBSD]], provide it as a package which must first be installed.

;Notes
# Some older versions of bzip2 may not be able to handle files larger than 2 GB, so make sure you have the latest version if you experience any problems.
# Some older archives are compressed with gzip, which is compatible with PKZIP (the most common Windows format).
