What is a .73l file?

A .73l file is a log file generated by the 7-Zip file archiver. When 7-Zip performs operations like archiving or extracting files, it can create a log to record the process. This log includes details such as the files processed, any errors encountered, and the success or failure of the operation. These files are primarily for troubleshooting and verifying that archive operations completed as expected. They are plain text files, making them easily readable with standard text editors.
