These are compressed log files. Since the files are too large, I split them into several parts. They are in 7z archive format. The filenames should end with 001–003, but because files with 001–003 extensions could not be uploaded, I added “.7z” to the end of each filename.

When I use WinSCP to download a large number of patent files (possibly around 500,000 files), the program crashes and closes by itself. I checked the program’s log file but did not see any error messages. However, when I open the Windows Event Viewer, I can notice that the software crashes due to some reason.
