What is a DEB file

DEB files mostly belong to dpkg by The Debian Project. DEB is an extension used to label software packages for the Debian Linux distribution and its derivatives. Debian packages usually contain all of the data required to install a group of related commands or features. DEB packages in their current form are ar archives and usually contain three types of files:

• Debian-binary: contains the the package format version number.
• Control archive: a TAR file with the label 'control.tar' which contains executables including preinst and postinst scripts, other package meta-information such as a brief description of the package, MD5 checksums, configuration files, man/info pages, copyright information, etc.
• Data archive: a TAR file with the label 'data.tar' that contains installable files.

Other features:

• Nomenclature: Debian packages follow a standard file naming convention: <packagename>_<VersionNumber>_<DebianRevisionNumber>_<DebianArchitecture>.deb
• Security: Debian packages can be signed with the GNU Privacy Guard, and support checksums to verify their authenticity.
• Adoption: DEB packages are standard across a variety of different Unix and Unix-like operating systems including Ubuntu, Fink, Nexenta, etc.

How can I open a DEB file?

You need a suitable software like dpkg to open a DEB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your DEB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DEB file directly in the browser:. Just drag the file onto this browser window and drop it.

DEB file format:

If you know the file format, you can also find out how to open or edit the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the DEB files comes to the following conclusion:

The DEB file extension is used very often and is mainly used by one program with a specific format. However, the following two file formats are common:

• 98% of all DEB files are associated with Debian Linux Package files, which internally utilize the well-known LinuxAr format. This file format is an archive created by the Unix archiver "ar", which stores multiple files together in a single archive, that allows each one to be separately retrieved later. The contents of these files cannot be read by a human; only a computer program can interpret the data. The files are 62 KB to 88 MB in size, with a median of 3 MB. It is a modern file type. The files contain the following words: !<arch>, binary, control and debian. These files are attributed to iphoneos, iosgods, ubuntu, stable, virtualbox, android, current, google, studio and cros.

All other DEB files (2%) have no uniform format. Often described as latest, linux, chrome, steam, code or nsepa. Just click the "Choose your .deb file to view" button on this page to find out what your DEB file is.
