Convert A13 to 008

Understanding a13 and 008 file formats

A13 and 008 files are both associated with split archive files, commonly created by file compression and archiving utilities. An .a13 file is typically the 14th part of a multi-volume archive (with extensions like .a00, .a01, ..., .a13), often generated by programs such as ARJ or WinRAR. Similarly, a .008 file is the ninth part of a split archive (with extensions .001, .002, ..., .008), usually created by utilities like 7-Zip, WinRAR, or HJSplit. These files are not standalone and require all parts of the archive to be present for extraction.

How to convert a13 to 008

Direct conversion between .a13 and .008 is not standard, as both are segments of different split archive sets. However, if you need to repackage the contents from an ARJ/WinRAR split archive (.a13) into a 7-Zip or HJSplit split archive (.008), you must first extract the complete archive and then re-archive it using your preferred tool with the desired split size and naming convention.

Step-by-step conversion process

1. Ensure you have all parts of the original split archive (e.g., .a00 to .a13).
2. Use WinRAR or ARJ to extract the full contents:
   • Open the first part (e.g., .a00 or .arj) in WinRAR.
   • Click Extract To and choose your destination folder.
3. After extraction, use 7-Zip to create a new split archive:
   • Right-click the extracted folder or files.
   • Select 7-Zip → Add to archive...
   • Set Archive format to 7z or zip.
   • In Split to volumes, bytes, enter the desired size (e.g., 50M for 50 MB parts).
   • Click OK to create the split archive (resulting in .001, .002, ..., .008 files).

Best software for the conversion

• WinRAR – for extracting .a13 and other ARJ/RAR split archives.
• 7-Zip – for creating new split archives with .001, .002, ..., .008 extensions.
• HJSplit – for splitting files into numbered parts, including .008.

Summary

While you cannot directly convert an .a13 file to .008, you can extract the original archive and repackage it using 7-Zip or HJSplit to achieve the desired split archive format.
