The last time I introduced the features of “Airxzip”, this post says one of the features.

Change file system and set filemode and directory mode

var writer:ZipFileWriter = new ZipFileWriter(ZipFileWriter.HOST_UNIX);
writer.open(File.desktopDirectory.resolvePath("airxzip_unix.zip"));
	
writer.setDirMode("0700");
writer.setFileMode("0700");

writer.addDirectory("Foo1");
writer.addFile(File.desktopDirectory.resolvePath("image.jpg"),"Foo2/image.jpg");

writer.setFileMode("0766");
writer.addFile(File.desktopDirectory.resolvePath("image.jpg"),"Foo3/image.jpg");
writer.close();
unzip -Z airxzip_unix.zip 
Archive:  airxzip_unix.zip   1550668 bytes   3 files
drwx------  1.0 unx        0 b- stor  6-May-10 20:11 Foo1/
-rwx------  2.0 unx   777835 b- defN 14-Jul-09 14:32 Foo2/image.jpg
-rwxrw-rw-  2.0 unx   777835 b- defN 14-Jul-09 14:32 Foo3/image.jpg

Default filetype is “ZipFileWriter.HOST_WIN”.
So If you want to create zip file for Mac or Unix/Linux , Please set “ZipFileWriter.HOST_UNIX”.

var writer:ZipFileWriter = new ZipFileWriter(ZipFileWriter.HOST_UNIX);

Default file system

 unzip -Z async_airxzip.zip 
Archive:  async_airxzip.zip   775492 bytes   3 files
-rw-a--     2.0 fat        6 b- defN  6-May-10 20:12 sample.txt
drwx---     1.0 fat        0 b- stor  6-May-10 20:12 Foo1/
-rw-a--     2.0 fat   777835 b- defN 14-Jul-09 14:32 Foo1/image.jpg

Airxzip

Airxzip is a library in ActionScript3 (AIR).
Fzip is ActionScript3 library too.
But I have some problems to use it.
So I made “Airxzip”.

Airxzip has following features …

1) Specialize in AIR
It becomes possible for the access to begin at the end of the file ( zip entry infomations ),
It does not to depend on the size of zip file.
So It is able to access information quickly.

2) Async upzip
Airxzip has 2 unzip method. ( unzip() and unzipAsync() )

3) PKWare encrypt/decrypt

4) File attribute ( Zip mode only)
Enable to set file attirbute.
ex) “0700” “0755”

5) Japanese filename
Mac OS and Unix filename is UTF-8, Windows is Shift_JIS.
And Mac OS UTF-8 and Unix UTF-8 is not same to handle Hankaku-kana.
So AIrxzip resolve these difference automatically.
