Convert 7Z.010 to 004

Understanding 7z.010 and 004 file formats

7z.010 and 004 are not standalone file formats, but rather parts of a split archive created by the 7-Zip compression tool. When a large file or folder is compressed and split into multiple volumes using 7-Zip, the resulting files are named sequentially, such as .7z.001, .7z.002, ... .7z.010. The 004 file in this context refers to .7z.004, which is simply the fourth part of the split archive.

Purpose of split archives

Split archives are used to break up large compressed files into smaller, more manageable pieces for easier storage or transfer. Each part is essential for reconstructing the original data. Conversion between 7z.010 and 004 is not applicable, as both are just segments of the same archive set.

How to extract split 7z archives

To access the contents of a split 7z archive, you need all parts (from .7z.001 up to the last part, such as .7z.010). Extraction is performed on the .7z.001 file, and the extraction software will automatically use the subsequent parts.

Best software for handling split 7z files

• 7-Zip (Windows, free): The original tool for creating and extracting 7z split archives.
• PeaZip (Windows/Linux, free): Another excellent tool supporting 7z split archives.
• The Unarchiver (macOS, free): Supports extraction of split 7z files on Mac.

How to extract a split 7z archive using 7-Zip

1. Ensure all parts (.7z.001 to .7z.010) are in the same folder.
2. Right-click on the .7z.001 file.
3. Select 7-Zip → Extract Here or 7-Zip → Extract to "folder".
4. Wait for extraction to complete. The software will automatically use all parts in sequence.

Important notes

• You cannot convert 7z.010 to 004 or vice versa, as both are just parts of a split archive.
• All parts are required for successful extraction. Missing any part will result in errors.
