Open .1 File

Files of extension 1 can find various applications, here are some of
them:

File Splitter

The file extension 1 is used, in principle, by the File Splitter software
to assign a number to a volume of a divided file.

File Splitter is an application for Windows that allows you to either
automatically divide or join the different parts of a large file into
smaller and more manageable parts, in order to share them.

This being the case, when a large file is created and the user wants to
split the file into smaller volumes, then file extension 1 is given to the
first file in the split file.

Mozilla Firefox

In some cases, Mozilla Firefox will also use the extension 1, giving it
to files that store data about cookies, images, and pop-up permissions.

Mozilla Firefox is a free and open source web browser developed by
Mozilla Corporation.

Unix

In this section, a file 1 is a manual page used by the Man utility, a
Unix program used to view user manuals.

Man is a Unix-based systems tool used to document and learn about
commands, files, system calls, etc., on a GNU / Linux operating system.

This being the case, file extension 1 contains level 1 user manuals
stored in plain text and separated into several segments and delimited by
standard markers.

Since Unix man pages are stored in plain text format, they can be created
and edited with any text editor, for example GNU Emacs.

Software for working with files 1

Open EDB File

An EDB file extension is a database created by Microsoft Exchange Server.

Microsoft Exchange Server is a mail server and calendar server developed
by Microsoft. Runs exclusively on Windows Server operating systems.

In other words, the EDB file serves as the primary repository for
Exchange-saved mailbox data.

On the other hand, the EDB file stores both in-process and stored
non-SMTP messages, since it is formatted using a b-tree structure, which
includes a top-level node and many child nodes.

The EDB files used for the Exchange information store are identified as
PRIV1 and PUB1, and eventually each of them has a corresponding STM file
that contains SMTP messages.

Software for working with EDB files

EDB files are not designed to be opened manually by the user, since they
are directly referenced by the software whose link you will find below:

Open MSO file

An MSO file is a macro reference file created by saving a Microsoft Office document as a web page.
It contains information about macros and OLE objects (Object Linking and Embedding) included in the original file and can be referenced by the created web page as a style sheet.
MSO files can be opened with a text editor, but this will be useless as the characters will be unreadable due to the content being encoded.
If you see the MSO file as an email attachment, do not open it as it most likely contains a virus or other suspicious program.

Inline E-mail Attachment

File sent as Microsoft Word 2000 email attachments; often called
‘Oledata.mso’, it contains information that allows the attachment to be
rendered in the email message.

File extensions are used by Windows operating system to specify what kind of information is stored in the file. Every file in Windows OS needs to have file extension and file extensions are used by Windows to determine which application it should use to open the file. Every application installed on Windows OS places information about which extensions it could open into the Windows registry and Windows uses this information to determine which application it should launch when user double-clicks on the file. If application which can open MSO file is not installed, then Windows will show ‘Windows can’t open MSO file’ message and buttons to either select an application on the computer which can open the file or to search the web for the application which can open MSO file.

Open ZIP File

ZIP is a compressed file format used to archive several files together and compress them to reduce the space used. It is a very common compression format and is supported by almost every modern OS natively. Popular tools for creating and unpacking zip files include WinZip, Stuffit Expander, etc.

Open XPI File

XPI refers to the Extension Archive files. They are primarily associated with the web browsers like Mozilla Firefox. These files are the compressed installation archives which are used by browsers like Firefox, Thunderbird and SeaMonkey. The contents of these files may vary from primary software component programs to the software extensions like the web plug-ins. There is a very simple way of opening such files. They can be simply dragged and dropped into the window of a web browser. The browser will itself open the file.

Similarities of these files with .zip files

The files with the XPI are actually very much similar to the zip files. They are also compressed files which is responsible for their small sizes. Thus, when they are opened, they first need to be decompressed and only then they can be accessed. When these files are opened in a web browser, they use some add-ons. The most common ones used by them are Alexa and PR add-on indicators. They also make use of some of the other types of plug-ins which are essential to the working of the Mozilla applications.

So, how do these files work?

These files install a browser extension when they are opened in a web browser. To gain access to and to install the local version of such files, opening them in any web browser like Firefox is the best way to go. In general cases, a file like this will automatically get installed into the system through the web browser and will be available for general use after the browser is restarted once.

So, how is this file format different from the other .zip files?

In technical terms, the XPI is nothing but the renamed versions of the ZIP files and this is the reason why any program meant for the compression or archive purpose will open the XPI file for decompression, once the XPI file is renamed from XPI to ZIP. The . xpi files are meant to provide extendibility to the browser. Thus, these files can be easily accessed through 2 different ways. Firstly, by opening them in an appropriate web browser where they get automatically installed and secondly, by renaming their extension to ZIP and then decompressing them with any archive program.

Open XLSX File

Any computer user must have heard about .xlsx file, especially if they have been using Microsoft Excel. The files with the .xlsx extension are associated with the Microsoft Excel Open XML Spreadsheet Format. This is a new extension format which is used to save the files for Microsoft Excel. These files are pertaining to the Microsoft Excel Version 2007 and above only. The versions which were created earlier to the 2007 version used to save the files in the format of .xls extension. The difference between the two is that the .xlsx is embedded with the compression and decompression feature for the purposes of size reduction and better distribution of data.

So, how does one access this type of file format?

The simplest way to execute and access a XLSX format file is by opening it with the Microsoft Excel program (version 2007 or newer). Though for the time being, these files are only executable in the versions 2007 or later, it is claimed by the Microsoft Corporation that the earlier version would now be equipped with the feature of the conversion of .xlsx files to the .xls files and vice versa. Till the time such a facility is provided, these files can be converted using the Microsoft Office Compatibility Pack.

Why was .xls replaced to .xlsx?

Before the XLSX format came into being, the file format .xls was the most common format which was used by the Microsoft Office programs for the data transfer. But in the recent times, the improved .xlsx file extension format has replaced the .xls format due to better system facilities like compression, faster data transfer and more storage capacity. It is expected that as the newer versions of the Microsoft Office programs keep becoming more widely used, the popularity of the .xlsx format will also increase substantially .

So, what is different with the .xlsx format?

The spreadsheets in Microsoft Excel which use the XLSX format, use the Microsoft Office Open XML format which was absent in the files with the .xls format. An advantage of the XML format is that it makes the reading and accessing of the .xlsx files, comparatively easier for the other programs such as OpenOffice.org. The other different applications which may support the .xlsx files are LibreOffice, KOffice, TextEdit, IBM Lotus Notes, Google Docs, OpenOfficeCalc, PlanMaker, Abiword and Kingsoft Office
