Files with extensions like .001, .002, and so on are typically parts of a larger file that have been split into smaller pieces for easier distribution. Joining these files back together is essential to restore the original file. This comprehensive guide will cover five different methods to join these split files using various tools and software. Each method is explained in detail to ensure you can choose the one that best fits your needs.
