Download some materials from the Internet. After some files are decompressed, you will find the _ MacOSX folder, Mac, Apple folder, and Lenovo .... well, just think of this. I can only understand it after searching on the Internet (in fact, I can guess it if I continue to think about it ):
As their development environment. For example, many core figures from leading network framework organizations choose Mac as the development platform, and many WordPress plug-ins and templates are developed by authors on Mac.
Compressing directories in Mac is a very easy task. You just need to right-click the Directory and choose "compress ..." You can upload the package to the Internet for people to download. However, there is a problem that apple, like other big software companies, is very good at misinterpreting and attaching the meaning of users. Many times it is not exactly what you mean. For example, in this case, do you think Mac only adds what you want into the compressed package? This is not the case. Apple also writes some "metadata" to the file while compressing the file ", this is intended for other Mac users (like thumbs that Windows will add to the image directory. dB to facilitate the display of preview images ).
The files generated by metadata are "_ MacOSX". These files themselves are hidden in the MAC system and are indeed convenient for user operations. However, plug-ins, templates, and other works should be used by many people. Most of them are Windows operating systems, while windows is never an apple. __macosx becomes a junk file.
If you are a plug-in or template author or are disgusted with these files, you can use the cleanarchiver software to compress your directories and files. Cleanarchiver supports multiple formats such as gzip, Bzip2, zip, DiskImage, stuffit, and stuffit X. You only need to select the desired compression format in the cleanarchiver window, drag the Directory and file to be compressed to the cleanarchiver window, and finally confirm the storage location and name. cleanarchiver will compress a compressed file without _ MacOSX.
