1. Create a new notepad file with any name.
2. Open the notebook file and write the following sentence:
Among them, “.lib” is the specified format; “D:\a.txt” is to create a notepad file named a.txt on the D drive after extraction. These can be changed as needed.
3. Save the notepad file again, and then change the format of the latter file to “.bat”;
This completes a batch file, put it in the location where you want to extract the files, and then you can extract the files of the same format in the folder.
