Actionscript 3 class library to load standard ZIP archives and extract/decompress contained files
by Carlos Pinho, June 23rd, 2007

flash_platform_icons.gifClaus Wahlers released the update for FZIP, a AS3 class library to load, extract/decompress files.

Main updates are:

  • Added support for Adobe Air. The Adobe Air runtime provides a low level inflate method, making it possible to load any ZIP archive and decompress compressed files without the need of injecting Adler32 checksums.
  • Added FZipLibrary class for higher level access to files in a ZIP archive. “FZipLibrary processes files (based on file extensions) from an FZip instance and converts them into usable formats. Files can be converted to either a BitmapData or DisplayObject classes. Data embedded in SWF files (like classes) can also be retrieved. Flash’s built-in Loader class is used to convert formats, so the only formats currently supported are ones that Loader supports. As of this writing they are SWF, JPEG, GIF, and PNG.”
  • Bug fix: There was a problem with filenames containing special characters. Filename encoding now defaults to UTF-8. In case the filenames are encoded differently in your ZIP, you can specify the encoding in the FZip constructor.

Brgds,

    Is there a way to zip a group of file using adobe air + flex? or HTML + Javascript + Adobe AIR? I am making a flickr photo uploader with AIR and was looking for a way to simplify it by just zipping all the pics

    Is there a way to catch the error that occurs if you try to load a file which is not a zip file. (My application lets the user browse for a file to unzip – if he selects some other random file, I want to display an Alert).
