I am attempting to use 7 Zip through the command line. As you can see below, using the command 7z l lists the 3 files in the target zip file.

However, when I attempt to actually unzip the file, I get a "no files to process error". I've never tried unzipping from cmd before. Do I have to try to dig into the zip file to extract those 3 files?

To begin a session, open a terminal window. Invoke the version of 7Zip you are using by entering "7z" for P7Zip (7z.exe), or "7za" for 7Zip for Windows (7za.exe) to start either the P7-Zip or 7za application prior to entering commands.
If 7-Zip option isn't appearing in the context menu and the option Integrate 7-Zip to shell context menu option is selected under Options, it's likely because you have installed the 32-bit version of 7-Zip on your 64-bit PC. You can open Programs and Features to check the version of 7-Zip.
Use the “a” command to create a new archive file which can end in 7z, XZ, GZIP, TAR, ZIP, and many more. How to zip a file using 7-Zip command line? Use the “a” command to add files to the ZIP file.
Another method of fixing the header error of your 7-zip file is to use the command prompt i.e run CMD to repair or restore the corrupted/invalid Zip file. Use these steps and you will fix the error: Step 1: Open the "Command Prompt" of your system as an administrator and not as a standard user.
Downloading error: The error of 7-zip file may also occur while downloading from the internet due to slow connection or bandwidth etc. that can also lead to CRR error. File header corruption: File header is the place to contain the file name, size, and extension, etc. These details help in accessing the file.
The "u" command in 7-Zip stands for update. This is a useful command and is great when you want to replace old files in your archive with newer files. This prevents needing to decompress and recompress the entire archive.
The option is -o, not o-. Run the command like this:
7z e recording_20130731180507.zip -o"C:\users\User1\documents\folder1\test"
