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.
