The .7z format is popular for sharing massive datasets because of its high compression ratio.
It is frequently seen in GitHub releases or automated build systems where a file is tagged by a date, such as 2024.12.24.7z or 2026.03.24.7z . For instance, the Travel Modelling Group uses this format for XTMF software builds [27]. 2. Large Datasets (Research & Training)
In computer vision research, the RailEnV-PASMVS dataset hosted on Zenodo includes a specific file named 24.7z , which is part of a larger 84 GB collection used for training AI in 3D reconstruction [22].
Research repositories often split large data into numbered volumes (e.g., 01.7z , 02.7z , ... 24.7z ) to make them easier to download [22]. 3. Malware Analysis & Cyber Security
Services like ANY.RUN have flagged files with names like 175-33-26-24.7z or Malware.2024.12.24.7z as malicious, often associated with phishing or Remote Access Trojans (RATs) like DCRat [2, 6].
