File extension 001 is associated with several archive utilities or compression tools, which are used, or used in the past, the 001 file extension for its multi-volume files or archives, such as WinRAR (see part1.rar) or 7-Zip (see 7z.001).
The general file sequence is 001, 002, 003, 004, etc. You will need all parts of the multi-volume archive to extract the content successfully.
Sometimes, the 001 file extension doesn't mean the first part of the multi-volume archive but the first part of a split file. You first have to merge divided files (001, 002, 003, etc.) into one file (usually split archive) via split tools. Afterward, you can use a compression utility to extract data from the merged file.
It can also be a big game data file from various computer games.
To open or extract the content of the multi-volume archive, just put all the parts in the same directory and extract the first part in your favorite archiver, such as WinRar or 7-Zip.
Only a complete archive can be converted into another archive or compression format. The easiest way to convert the entire multi-volume archive is to decompress the archive with the supported archiving or compression tool and repack the content with another compression or archive application of your choice.
