Extract text from WinRAR split archives (R1)
To convert R1 archive parts to another format, you need WinRAR or other Compressed software.
To convert other file formats to the "Split Archive Part" file type, you need software like WinRAR or a similar tool.
The .r1 file is a split archive volume created by WinRAR. When users compress data that exceeds email attachment limits or FAT32 file system constraints, they split the final archive into smaller, sequentially numbered chunks (e.g., rar, r00, r01). The .r1 file is simply one piece of this larger puzzle.
Standard archive tools like 7-Zip and WinRAR can extract these files on Windows, while macOS users typically rely on The Unarchiver. For more details on the core compression algorithm, you can read about the RAR format on Wikipedia.
The primary disadvantage of a .r1 file is its strict dependency. It is completely useless on its own. You cannot view or extract its contents unless every single volume of the archive sequence is present in the exact same directory. Furthermore, the RAR algorithm is proprietary, meaning web browsers, mobile devices, and most base operating systems cannot read these files natively without installing third-party utilities.
Directly converting a single .r1 file to another format is mathematically impossible without first reassembling the payload. The best workflow is to extract the original contents and repackage them into a widely supported, open standard like ZIP or 7Z.
Because it is a closed, proprietary fragment of a larger data structure, this file format is difficult to open or convert directly online. Often only the original software can properly read or export the data sequence. We can still identify the file format, inspect the headers, and show internal metadata. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your R1 file, detects the exact format, and lets you read the text inside.
Users also converted R0, R09 and R07 files.
If you want to convert R1 file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use WinRAR or similar software from the "Multi-Volume Archive Storage" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to R1, try WinRAR or another comparable tool in the "Multi-Volume Archive Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our R1 converter.
