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.
ARC format uses lossless compression algorithm to store data – ARC archive reduces the overall size of the files/folders without loss of file information.
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.
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.
When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the ARC extension without any issue. However, if you still have problems with this, you may use the option of ARC file conversion to a different format.
We hope we helped you solve the problem with the ARC file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.
There can be more reasons which determine that you are not able to open the ARC file (apart from the lack of the proper application installed).
First - the ARC file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the ARC file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the ARC file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the ARC file has not been completed and it cannot be opened properly).
