How to open ARC files

If you cannot open the ARC file on your computer — there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports ARC among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the ARC file can be found in the table. Now just download and install the appropriate application.

Possible problems with the ARC format files

The inability to open and operate the ARC file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the ARC Lossless Data Compression And Archive Format file. Below is a list of possible problems.

• Corruption of a ARC file which is being opened
• Incorrect links to the ARC file in registry entries.
• Accidental deletion of the description of the ARC from the Windows registry
• Incomplete installation of an application that supports the ARC format
• The ARC file which is being opened is infected with an undesirable malware.
• The computer does not have enough hardware resources to cope with the opening of the ARC file.
• Drivers of equipment used by the computer to open a ARC file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the ARC file should operate with your programs without any problem. If the problem with the ARC file has not been solved, it may be due to the fact that in this case there is also another rare problem with the ARC file. In this case, the only you can do is to ask for assistance of a professional staff.

ARC Lossless Data Compression And Archive Format

What is ARC file?

ARC file is a compressed archive file format designed by System Enhancement Associated (SEA). Compression reduces the size of the archive containing one or more files or folders to facilitate sharing of files with other users.

Characteristics of ARC file format

ARC format uses lossless compression algorithm to store data – ARC archive reduces the overall size of the files/folders without loss of file information.

Creation and popularization of ARC format

ARC compression method was introduced in the early 80s and quickly reached its peak of popularity. It was a time of dynamic growth of the internet, and many modem users welcomed the ARC format with open hands as it was a very convenient way for them to share data. This format was especially popular among Bulletin Board System (BBS) users. Internet connection speed at that time was rather slow, and ARC file offered smaller file sizes and thus required less bandwith when uploading or downloading the file. Nowadays ARC algorithm is rarely used as there are more advanced and better compression methods available on the market.

New standard of file compression and archivisation

It is worth mentioning that until the ARC format was introduced, archivisation and compression of data were two separate processes. Only after the introduction of ARC file format those two processes were joined into single process – a considerable innovation at that time. This method was achieved by combining functions of two separate programs – SQ for compression and LU for archivisation.

Programs which support ARC file extension

The list that follows enumerates programs compatible with ARC files, divided into 2 categories based on operating system on which they are available. Files with ARC extension, just like any other file formats, can be found on any operating system.
