Use a file archiver tool like 7-Zip (on Windows) or The Unarchiver (on macOS) to extract the files from SS-Nin-022_s.7z.001 . Note: If this is a multi-part archive, ensure you have all files (e.g., .002, .003) in the same folder before extracting.
Examine the file type (e.g., PDF, HTML, Word doc, CSV) and data within.
Because this is a specific, likely proprietary or specialized file (often used in data archiving or sharing), I cannot access its contents.
