Hmm. I wonder if most people are familiar with 7Zip? I have to use Windows at work, and this is the "zipper/unzipper" of choice. It's free and better than just about anything I've had to use in the past.
Right-click a zip file and "open with 7Zip" or "extract here" and it's done.
The web site is at https://www.7-zip.org/ and from there the list of files covered is:
* High compression ratio in 7z format with LZMA and LZMA2 compression.
* Supported formats:
Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
Unpacking only: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.
* For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
* Strong AES-256 encryption in 7z and ZIP formats
That should be enough for everyone! Of course, we have to convince "most people" to get their finger out and do something for themselves!
