\nThe other day I compressed a folder into 7z format to submit somewhere, and was told only zip format would be accepted. I was using 7-Zip, which also compresses to zip format, so I just compressed the folder that way instead and sent it off. Yet, I was surprised that zip would be accepted, but not 7z. <\/p>\n
I decided to look into the matter and found an article about it on howtogeek.com<\/a>. The article<\/a> compares zip, 7z, and a couple of other formats.<\/p>\n 7z might achieve more compression than the others – not necessarily by much. Yet, to me, that’s not the point; I’m interested in reliability. Sometimes I use 7z format, sometimes zip, but I mostly use the 7-Zip program to create the compressed file (which some call an archive) and to unpack a compressed file I receive. 7z, as I understand, is 7-Zip’s own compression flavour. However, 7-Zip will produce and decompress zip and other formats as well.<\/p>\n 7-Zip continues to perform while the built-in compression utilities on some of my computers have given up. I assume (perhaps wrongly) that everyone else uses it, too, so I was surprised when someone would accept zip but not 7z.<\/p>\n Source:<\/p>\n 7-zip.org<\/a><\/p>\nJack of Oracle Tutoring by Jack and Diane,<\/a> Campbell River, BC.\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Self-tutoring about file formats: the tutor mentions 7z and zip.
