ARCHIVING FORMATS |
ArcThemALL! uses 7Z.dll as the engine to compress and extract archives. SUPPORTED FORMATS FOR COMPRESSION ZIP: Mainstream archiving/compression format. Optional 256-bit AES encryption. You might use ZIP format when you need widest compatibility for file distribution, since it is accessible with compression utilities integrated in Windows and in most file managers. The Compressed Folders utility integrated in Windows and used by some file managers only supports Deflate compression method. |
7Z, 7Z SFX (self-extracting archives): Archiving format with very high compression ratio, fast compression and decompression. Supports very large file sizes and Unicode filenames. Optional 256-bit AES encryption. 7Z format is not compatible with Windows' compression utility, and requires external software for compression/decompression. |
This page from 7‑Zip's on-line documentation includes a helpful overview of archiving compression methods and their performance. |
