Convert 018 to 003

Understanding 018 and 003 file formats

018 and 003 files are not standard file formats, but rather parts of a split archive. These files are typically created by file splitting utilities such as WinRAR or 7-Zip when a large file is divided into smaller segments for easier distribution or storage. The numbers (e.g., .001, .002, .003, ..., .018) indicate the sequence of the parts. They are not meant to be converted from one to another, but rather to be reassembled into the original file.

How to combine 018 and 003 files

To access the content, you need to join all parts of the split archive, not convert between them. This is done using the same software that created the split files. The process involves placing all parts (e.g., .001, .002, .003, ..., .018) in the same folder and using an extraction tool to reconstruct the original file.

Best software for joining split files

• 7-Zip (Windows, free): Right-click the first part (usually .001 or .rar), then select 7-Zip → Extract Here.
• WinRAR (Windows, paid with trial): Right-click the first part and choose Extract Here or Extract to [folder].
• Keka (macOS, free): Drag the first part onto the Keka window to extract.

Important notes

• Ensure you have all parts of the split archive before extracting.
• Do not rename the files, as the sequence is crucial for successful extraction.
• There is no direct conversion from .018 to .003; these are sequential parts, not different formats.

Summary

To access files split into .018, .003, and similar parts, use extraction software like 7-Zip or WinRAR to join and extract the original file. These files are not meant to be converted between each other, but rather reassembled as a whole.
