Open 1 File

The 1 file is a Unix Section 1 Main Page file type. The file is categorized as a miscellaneous file and comes in the text format. The 1 file is a manual page and also referred to as a "man page". It is equally used by Man utility, which is a Unix program used for viewing the users' manuals that are stored in plain text and also divided into different segments, with each of them being delimited by standard markers.

The level 1 user manuals mainly describe general commands for the Unix operating system. This format is stored up in files containing the name of the particular command and the .1 extension is added as a suffix to the file name. A manual for "cmd_example", for example, will have the "cmd_example.1." file name.

Unix man pages can be stored in plain text format and, therefore, can be edited and created using any of the common text editors. In most instances, Unix man page files are compressed into .GZ files; they, therefore, have the ".gz.1" extension; this type of extension is referred to as a compound extension. The Unix man pages can also have the ".2" extension up to ".8" extension for several other sections. The ".2" extension can be used for System Calls documentations. The 1 file is in association with 1 to 8 and it might be a part of a version number, OpenOffice.orrg1.0.1, for example. Let's see how to open 1 file.

How to open a 1 file

Before you can open a 1 file, you will need suitable software. You will receive messages like "How do you want to open this file?" or "Windows cannot open this file", depending on the version of Windows operating system that you are using, if you do not have the appropriate software to use for opening the file. You can click either long-press on the file or right-click on it to access the drop-down menu that can help you to open the file. On the drop-down menu, click on "Open with" and then choose the particular application with which you can successfully open the application.

You can use Inno Setup Binary File to open the 1 file. You can also open the file with Mozilla from Mozilla-org. it supports Popup Permissions, Image, and Cookie. Furthermore, you can open the file using Pro/ENGINEER from PTC. Pro/ENGINEER is a backup file and a 3D product design product featuring several productivity tools capable of promoting best practices in design, as well as, ensuring complete compliance with company and industry standards.

Apple II operating system can also be used to open the 1 file. It is part of a multi-part archive and works just like Stuffit and The File Splitter in opening the 1 file.

Many of these tools are available for free and you can easily download them without having to pay for them or get any form of authentication. Even if you have to pay for any of the programs or tools, the paid ones are generally cheap and will not put a hole in your pocket. The programs are light and will not occupy much space on your computer.

File type: 3GP Multimedia File


The video and audio container format developed by the 3GPP (3rd Generation Partnership Project) is represented by the 3GP file extension. This file format is specifically designed to handle the transmission of multimedia contents using a third generation cellular phone and an existing Internet network connection structure. This is an inherent file feature for mobile phones that support video capturing capability. This third generation file format is also widely supported by both 2G and 4G cellular phone units. This format file is basically a simplification of the MP4 (MPEG-4 Part 14) container unit intended to lower the bandwidth and storage requisites to allow the accommodating of multimedia content in cellular phones.


Detailed information 

Category: Multimedia File
File format: Open-Source
Open with Windows: Apple QuickTime Player, Roxio Easy Media Creator, RealNetworks RealPlayer, VideoLAN VLC media player, MPlayer, MIKSOFT Mobile 3GP Converter
Open with Linux: VideoLAN VLC media player, MPlayer
The 3GP file extension saves video streams using MPEG-4 Part 10 (AVC/H.264), H.263, or MPEG-4 Part 2 specifications. The audio component of the file can be in the format HE-AAC, AAC-LC, AMR-WB+, AMR-WB, or AMR-NB. A file using the 3GP file extension is always in big-endian which means that the most significant data bytes are transferred and stored first. It also primarily describes the bitrate along with the sizes of the image. This format file is related to GSM based mobile phones. The file created under this format using a mobile communication device can be transferred to a computer system where it can be played back and even edited using various multimedia applications.

File type: Compressed


The 7Z file extension is the default format of the compressed archive developed by Igor Pavlov called 7-Zip. This file compression utility implements the LZMA compression, an open-source algorithm characterized by its higher compression ratio.

It can also produce archives with 256-bit (AES-256) encryption security coupled with a support for Unicode filenames and archive header compression. The maximum file size supported by the 7Z file extension is 16,000,000,000Gb. Aside from the default LZMA compression method, this utility also supports the BCJ2, Deflate, PPMD, and BZip2 compression algorithms.


Open 7z File

Category: Compressed Archives and Backup Files
File format: Open-Source
Open 7z file with Windows: 7-Zip, WinZip 12 Pro, ZipZag, WinRAR, PeaZip, ZipGenius, ConeXware, PowerArchiver
Open with Linux: p7zip, PeaZip, Zipeg
The 7Z file extension mainly features an open architecture with the capability of using virtually any available method for encryption, conversion, and compression. It is also one of the few compression utilities in the market that present a solid compression ratio. Due to its open-source architecture, it has the functionality of supporting optimized and improved LZ77 algorithm versions. It also supports 32-bit x86 executables for both BCJ and BCJ2.
The 7Z file extension has a variable dictionary size of up to a maximum of 4Gb with a compression speed of 1Mb per second on a 2GHz processor while exhibiting a decompression speed of 10 to 20Mb per second on the same type of processor. It also requires minimal memory requirement for its decompression operation including inherent support for hyper- and multi-threading processor functionalities.
