Convert 009 to 002

Understanding 009 and 002 file formats

009 and 002 files are not standard file formats, but rather parts of a split archive. These files are typically created by file splitting utilities such as HJSplit, 7-Zip, or WinRAR when a large file is divided into smaller segments for easier distribution or storage. The numbers (e.g., .001, .002, .009) indicate the sequence of the parts. They are not standalone files and cannot be converted directly from one to another; instead, they must be joined to reconstruct the original file.

How to combine 009 and 002 files

To work with 009 and 002 files, you need all parts of the split archive (e.g., .001, .002, ..., .009). The process involves joining these segments to restore the original file. This is not a traditional file conversion, but a reassembly process.

Best software for joining split files

• HJSplit (Windows, Mac, Linux): Simple and free tool for joining split files. Use Join function and select the .001 file; the software will automatically join all parts in sequence.
• 7-Zip (Windows): If the files are part of a split archive (e.g., .7z.001, .7z.002), right-click the .001 file and select 7-Zip → Extract Here.
• WinRAR (Windows): For split RAR archives (e.g., .part1.rar, .part2.rar), right-click the first part and choose Extract Here.

Step-by-step process using HJSplit

1. Ensure all parts (.001, .002, ..., .009) are in the same folder.
2. Open HJSplit.
3. Click Join.
4. Select the .001 file as the input file.
5. Click Start to join all parts into the original file.

Important notes

• You cannot convert a .009 file directly to a .002 file; both are parts of a whole.
• All parts are required to reconstruct the original file.
• If any part is missing or corrupted, the reassembly will fail.
