What Are RAR, .001, and PAR Files?
RAR, .001, and PAR formats are file types that serve different purposes but are common in Usenet due to their efficiency in storing and protecting data. Understanding them is essential for effectively managing Usenet articles.
RAR Files
RAR files are compressed archives that bundle multiple articles together, making it easier to transfer them over the Internet. RAR files are particularly useful for large articles because they allow for efficient storage and quicker access.
.001 Files
.001 files are part of a split archive. When articles are too large to be compressed into a single RAR file, they are divided into several smaller parts, with .001 being the first in the series. Each subsequent part (.002, .003, etc.) is a continuation of the full archive. All parts are required to reassemble the complete archive.
Par Files
PAR (Parity Archive) files are used to repair or reconstruct missing or corrupted files. They provide recovery information, so even if some parts of a split archive are lost or damaged, the full article can still be accessed by using the PAR files.
How to Open RAR, .001, and PAR Files on Different Operating Systems
Opening these files requires specialized tools, depending on your operating system. Here’s how you can handle them on Windows, macOS, and Linux:
How to Open in Windows
For Windows, a variety of free and paid software tools can open RAR, .001, and PAR files:
- WinRAR: This is one of the most widely used tools for opening RAR and .001 files. After installing, right-click on the RAR or .001 file and choose ‘Extract Here’ to decompress the archive.
- 7-Zip: A free alternative that also handles both RAR and .001 files efficiently. Similar to WinRAR, right-click the file and choose to extract the contents.
- QuickPar: This tool is designed specifically for PAR files. It allows you to verify and repair archives by reading the PAR data.
How to Open in macOS
On macOS, you have similar options for dealing with these formats:
- The Unarchiver: A free tool that supports RAR and split .001 archives. Once installed, double-click the file, and it will extract automatically.
- Keka: Another free utility that offers easy handling of RAR and .001 files. Drag the file into the app to decompress it.
- MacPAR deLuxe: This is the go-to for working with PAR files on macOS. It repairs and verifies your archives using PAR data.
How to Open in Linux
Linux offers a range of open-source tools for managing RAR, .001, and PAR files:
- p7zip: This command-line tool, available in most Linux distributions, handles both RAR and .001 files. To extract a RAR file, use the command `7z x filename.rar`.
- rar/unrar: Another command-line utility specifically for RAR files. Install it via your package manager (e.g., `sudo apt install rar`) and use `unrar e filename.rar` to extract the contents.
- par2cmdline: This command-line tool is perfect for managing PAR files. Use it to verify or repair damaged files by typing `par2repair filename.par2`.
Automatic Extraction in Newsreaders
Many modern Usenet newsreaders simplify the process by automatically opening, decompressing, and organizing files once they’ve been accessed: no need to manually handle RAR, .001, or PAR files. Newsreaders like SABnzbd, NZBGet, and Newsbin offer built-in features that automatically extract and repair articles, saving you time and effort. Once your articles have been accessed, the newsreader processes the files in the background, handling any decompression and verification without additional input.
By choosing a newsreader with these capabilities, you can streamline your Usenet experience and eliminate the need for manual extraction tools, making your access more efficient and hassle-free.
