RAR is a proprietary archive format, so you need third-party software to open and extract it on your Mac. In this post, we show you our favorite software to use for this, as well as some alternative ways to open .rar files in macOS.

RAR files are a common archive file format, alongside ZIP files. Named after the Russian developer who created them, Roshal ARchive files compress large amounts of data into a single .rar format file for convenient transfer.

You usually encounter RAR files when downloading content from the Internet. This is because .rar files reduce the download size and bundle documents and folders into a single download. RAR files also feature password protection and error recovery!

Most noticeably, macOS can extract ZIP files without downloading third-party software. Just double-click the .zip file and your Mac does the rest. This is because ZIP was released to the public domain in 1989, whereas the RAR file-format is still privately licensed.

RAR files benefit from more efficient compression than ZIP. The result is smaller archive files that are faster to transfer. Not only that, but RAR compression can work with larger amounts of data to begin with.

ZIP format files open natively with macOS, simply double click the .zip file and it extracts automatically. RAR format files are more complicated, but it is possible to open and extract .rar files on a Mac.

Keka is an open source alternative to The Unarchiver. As well as letting you extract and open .rar files on your Mac, you can also use Keka to create your own archive files in a range of other formats.

You can extract and open .rar files online, although you sacrifice an element of privacy in doing so. There are several websites available to use, we suggest you check user reviews to find the best one for you.

Visit the site of your choice and upload the .rar file from your Mac. Extract.Me even allows you to select .rar files from Google Drive or Dropbox. After uploading your file, the extracted contents should begin downloading to your Mac.

A .zip or .rar file is a file that stores and compresses one or more other files.

Files can go missing on your storage devices if they get corrupted, are infected with malware, are unknowingly hidden or automatically moved by a program without user acknowledgement. Files that have actually disappeared and haven't been moved or artificially hidden can often be recovered with undeletion software that scans the hard drive for files that are no longer recorded in the file allocation table -- the storage device data that tracks where files start and end. Undeleted malware-infected files can re-infect a system if they aren't probably cleaned before use.

As computer file systems have grown more sophisticated, the incidence of file corruption has become less common -- but corruption still can cause files to disappear from storage devices. Files can be corrupted by another program injecting bad data or by any type of error that stops the computer from writing the file when saving like power failure and system crashes. Files that haven't been completely downloaded or copied can also disappear from the system if the program handling the data transfer doesn't support transfer resumes. Additionally, hardware and software errors that cause either the file copy process to fail or incorrectly update the file allocation table can also cause files to disappear. Depending on how much of the file is corrupted, it may be recoverable through undeletion.

Malicious software, particularly worms, can run rampant on a storage device and start deleting files. Other malware like viruses can cause files to disappear because when they try to rewrite a file during the infection process they may cause write errors that corrupt the file. Worms are malware that delete and modify files on a computer before jumping to another computer on a network. Files deleted by a worm may be recoverable through undeletion; however, they should be scanned by an anti-virus program because they could be infected by the worm and start the file deletion process over again.

Files can disappear when the properties are set to "hidden" and File Explorer is not configured to show hidden files. Computer users, programs and malware can edit file properties and set them to hidden to give the illusion that the files don't exist and prevent you from editing the files. You can set File Explorer to show hidden files by opening "Control Panel," searching for "Folder, " clicking "Show hidden files and folders," selecting the radial next to "Show hidden files, folders, and drives" and clicking "OK."

Some programs, particularly media players, can rearrange and sort files on your computer. If a program rearranges files, they may be moved from their original location to a new location on the storage device: they're not gone, but if you look in the folder the files used to occupy, it will look like the files have disappeared. For example, Windows Media Player or iTunes may sort your music collection into folders by artist and album. Search for files in the Windows File Explorer search field to check if a program has relocated files.

Archive file is a file with .zip or .rar extension. It has been widely used for users to save a great number of files into one single file. You can collect photos, documents, videos, and even programs into an archive file and then transfer or send it to other storage devices or computers.

However, archive loss issue is still inevitable. A RAR file which contains some important photos or documents might be lost from your computer due to your accidental deletion or formatting. Under the circumstances, you will need an archive recovery program. Recoverit, or Recoverit for Mac, is a useful tool for you to perform ZIP recovery or RAR recovery with ease. This program can explore disks on your computer or storage devices that are connected with your computer and find deleted or formatted archive files instantly. If you are a Mac user, you can also restore archive files with Recoverit for Mac.
