Combines multiple files of similar types into a single stream to further exploit data redundancy and shrink the final archive.
) refers to a method where multiple files are treated as a single continuous data stream during compression. How Solid Compression Works del-fact.7z

In computational statistics, factorial designs (often abbreviated "FACT") generate massive intermediate datasets. Some legacy SAS, R, or SPSS workflows on Windows HPC clusters were configured to archive intermediate results as del-fact.7z (where "del" stands for "delta" or "delimiter"). After the main analysis finishes, the archive should be auto-deleted. But in poorly managed shared computing environments, thousands of such files accumulate. This theory explains why del-fact.7z appears on university HPC clusters and bioinformatics servers. It is often distributed through phishing campaigns, drive-by
