1.Install 7-Zip
Go to https://www.7-zip.org/.
Download the installer that matches your operating system (e.g., Windows 64-bit version).
Run the downloaded file and follow the on-screen instructions to install.


2.Prepare All Required Files
Save all split files (such as .001, .002, .003, etc.) in the same folder.
If you have the first file (usually .001), 7-Zip will automatically read the remaining files.


3.Extraction Procedure
Right-click the .001 file.
From the menu that appears, select “7-Zip.”
Choose one of the following options:

“Extract Here”: Extracts the files into the same folder.
“Extract to \”: Creates a folder with the same name as the file and extracts the contents into it.
“Extract...”: Allows you to specify the extraction destination.


4.Extraction Complete
If all parts are present, 7-Zip will automatically combine them and restore the original file.
After extraction, you can use the files as usual.
