\"unzip<\/p>\n

When you try to extract zipped file, sometimes it shows an error like below.
\nunzip error 22: invalid argument<\/code><\/p>\n

"Windows can decompose it. But Mac couldn't ..."
\nIt is strange. But there is a reason.
\nToday I introduce the reason of unzip error 22<\/code> in MacOS.<\/p>\n

<\/p>\n

<\/br><\/p>\n

Error<\/h2>\n

First, we should understand how the error occurs.
\nAs I wrote before, the error occurs when we try to extract zipped file in MacOS<\/strong>.
\nunzip error 22: invalid argument<\/code>
\nThen we failed extracting.<\/p>\n

<\/br><\/p>\n

Cause is update of MacOS ?<\/h2>\n

\"MacOS<\/p>\n

This error was reported on October 10th 2019.
\nIt was just after updating MacOS Catalina.<\/p>\n

\n

Upgraded to MacOS Catalina and now I cannot unzip any zipped file. I had no problems before. Also, moving the file or redownloading is not fixing it. Multiple files of different sizes failed. MacBook user here.\uff1f<\/p>\n<\/blockquote>\n

\n<\/div><\/div>\n

If it is due to OS Catalina, it seems that we can do nothing after updating<\/span>.
\nBut there is a solution for this issue.<\/p>\n

<\/br><\/p>\n

Root cause is character encoding<\/h2>\n

This unzip error happens only when we try to unzip zipped file that was composed by Windows<\/strong>.
\nThe error is not occured by zipped file of MacOS.<\/p>\n

It means that the error is caused by composing difference btween Windows and MacOS.
\nThe difference is character encoding<\/span>.<\/p>\n

Windows uses local character like Shift-JIS<\/span><\/strong>.
\nAnd MacOS and other Unix use UTF-8<\/span><\/strong>.
\nSometimes this difference makes error. And unzip error 22<\/code> is also caused by character encoding.<\/p>\n

MacOS function decompose zipped file with UTF-8.
\nWhen zipped file contains local character encoding, it would fail.<\/p>\n

It is same as previous article.<\/p>\n\t\t\t\n\t\t\t

File name is garbled when we decompressed zip file.<\/h5>\n\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/dd>\n\t\t\t\t<\/dl>\n\t\t\t<\/div>\n\t\t\t<\/a>\n\t\t\t\n

So solution is also same.<\/p>\n

<\/br><\/p>\n

Solution1: Use decomposing software<\/h2>\n

Instead of MacOS function, you can use decomposing software. So it checks character encoding and decompose correctly.<\/p>\n

There are some decomposing software like "Zip File Unarchiver" and "The Unarchiver".<\/p>\n

Solution2: composing settings<\/h2>\n

You can also avoid the error with using UTF-8 composing settings.
\nYou can set cu=on<\/code> in parameter on 7-Zip<\/a>. Then it would compose with UTF-8.
\nMacOS can decompose UTF-8-zipped file.<\/p>\n
