Springy

Springy is a simple to use, yet powerful archiving and compression utility for Mac OS X. Springy integrates seamlessly with the Finder and includes some very useful features. All archiving tasks can be done via Drag and Drop, system Services Menu or through Springy's Finder contextual menu.

Springy features at a glance:

• Open and browse the contents of an archive or disk image without extracting any file from it.
• Quickly extract all files or only files of choice from an archive or disk image.
• Quickly extract the whole archive or disk image by double-clicking its file in a Finder.
• Modify the contents of an existing archive or disk image: add, overwrite, delete and rename files in an archive or disk image.
• Full Drag & Drop support for archiving and extracting from and into Finder.
• Archiving and extracting tasks may be accomplished quickly and efficiently using system Services Menu in Snow Leopard or Finder contextual menu in Leopard and earlier.
• Edit and modify any file in an archive or disk image by double click.
• Live preview of many types of files inside archive, without extracting.
• Browsing files in archives and disk images and extracting particular file or folder using hierarchical Finder contextual menu.

Springy supports all most widely used archiving and compression formats: ZIP, TAR, RAR, 7Z, PAX, CPIO, CPGZ, GZIP, BZIP2, UNIX Compress, SIT, JAR, DMG and ISO disk images and some more. Support for even more formats will come in future releases.

What is new in this release:

• Fixes a bug in version 1.6 which could corrupt a ZIP archive after modifying it and quitting application.
• Open, read and extract support for 7Z archives (support for creating/modifying of 7Z archives will come soon).
• Open, read and extract support for Microsoft CAB archives.
• Springy is a Services Provider application, with Services Menu actions in Snow Leopard replacing Finder contextual menu plug-in (CM plug-in is still available in Leopard and earlier).
• Direct extraction mode, when the whole archive or disk image is extracted with double click on its file in Finder (application only).
• Flat file list view, which shows all files and folders in an archive without their mutual hierarchy (application only).
• Much more robust automatic archive type recognition.
• Speed gains when opening and processing ZIP archives (especially it they contain 20000+ files inside).
• Springy can now open and extract files from malformed large ZIP archives created by Apple tools Archive Utility and ditto, which don't follow Zip64 specification properly.
• Springy can now open empty uncompressed TAR, PAX and CPIO archives it created.
• Showing icon file preview immediately after icon generation, which gives more smooth and natural user experience (application only).
• New toolbar icons for the user preferences panel (thanks to Kenichi Yoshida).
• File sizes in Snow Leopard are shown the same way as system wide, using "power of 10" instead of "power of 2" calculation.
• Removed DMG disk image file type from the list of file types for which Springy can be set as a default handler. This feature caused quite some problems for some users (application only).
• Fixed bug when drawing last or a preview column after making an empty selection in a column view in Snow Leopard (application only).
• Fixed bug when rendering file preview in a preview column for some files in Snow Leopard (application only).
• Fixed bug which disabled permanently password text field in a save panel when creating DMG disk images (application only).
• Fixed bug which hanged CM plug-in after right clicking two or more times an empty file selection in Path Finder (contextual menu plug-in only).
