Which are utterly useless to non-Mac devices and users.įurther, by adding a duplicate set of hidden files to the zip archive, Mac essentially is doubling the size of the download zip file, which of course wastes bandwidth, disk space, and everything else. So anyone downloading your zip files on their Windows, Linux, or other non-Mac is going to see all those hidden files and folders. This is a real problem because many people use Mac to zip files to share on the Web. Why does macOS include hidden files in zip archives? It makes absolutely zero sense.

In fact quite the opposite: the hidden files serve NO purpose other than to waste bandwidth, time, energy, resources, etc. Thus the confusion: Why on earth are the hidden files added in the first place? They are completely excluded when unzipping on Mac, and never needed for any reason on any other machine. So again, all the hidden files/folders added by Mac are included in the unzipped files ONLY when the files are unzipped on non-Mac machines. This affects the URI scheme and DOM normalization of Widgets, so Web Apps will have to deal with it eventually… but not sure exactly how.Mac excludes all hidden macOS files when opening zip archives ( view hidden files enabled) If the widget engine needs to decompress the widget to disk, then it would take the NFC and convert them to the operating system’s native encoding (or store the files in memory, and reference them that way). The only way around this would be a *special* custom-built widget zipping tool that normalizes file name strings to NFC. Yes! holly crap! three different byte sequences corresponding to different character encodings.

“for example a French, German or Spanish Windows user cannot exchange files that contain French, German or Spanish accents with a French, German or Spanish Macintosh users” According to this email, the LimeWire guys also ran into a similar problem with regards to encodings in MacOS: It gets worst! because MacOS runs on some weird non-standard decomposed Unicode mode, you can only share zip files with other MacOs users. Implementers just encode file names however they want (usually byte for byte as they are in the OS… see table below). The Zip spec says that the only supported encodings are CP437 and UTF-8, but everyone has ignored that. So in this case, it is not Window’s fault.

If the underlying encoding of the file system on Linux is something else, you won’t be able to share files with other systems at all. This may seem ok, but when you decompress the zip file on Windows, which runs on encoding Windows-1252, the file names get all mangled. So, if the file system is in ISO-8859-1, the bytes are written in ISO-8859-1. The Zip file gives no guidance as to how file names inside zip files are to be normalized.Ĭonsider, when a zip file is created on Linux, it just writes the bytes for the file name in the encoding of the underlying file system. The Zip spec does not seem to know that there are normalization models for UTF-8, when there are actually 4 (or more, because there is some non-standard ones too!). It is ubiquitous and dependable… so long as you don’t want to share files across cultures. As people know, Web Apps is depending on Zip as the packaging format for Widgets. I’ve written about some of the issues with depending on zip as a packaging format in the past. Jason on Zip files and Encoding – I hate you.Pattabi on Dynamic function names in JavaScript.
