Easy-BZ Information

Simple, Effective Compression

Easy-BZ is a compression tool which allows extremely tight compression and quick decompression. Based on the BZip2 standard and optimized for the Macintosh platform, an easy-to-use, effective BZip2 compressor has finally been brought to the Mac OS.

Easy-BZ takes advantage of the latest advantages of the Mac OS 8. Its user interface is designed entirely around the new Appearance Manager, and it supports Navigation Services if installed. If you don't have the Appearance Manager installed, you can download it directly from the Easy-BZ web site.

If you like Easy-BZ, try Easy-GZ! It is a GZip compression program with an interface similar to Easy-BZ. Check for more information.

Frequently Asked Questions

* Can I use Easy-BZ to compress my applications?
- Currently, no. The BZip2 format is limited to data files only; it is unable to parse information in the resource fork of a file (where Mac OS-specific information is stored). If you try to compress a file with Easy-BZ that contains a resource fork, the resource information will be discarded-this would make normal Mac OS applications unusable. However, almost all data files are fully BZ-compressible. (A future version of Easy-BZ may attempt to address this limitation.)

* Easy-BZ won't start; it wants "AppearanceLib."
- Easy-BZ is very reliant on the newest features of Mac OS 8. It uses the Appearance Manager to improve the look and feel of the Mac OS interface. You can download this extension from the Easy-BZ web site; install it and restart to get Easy-BZ to run.

* I transferred an Easy-BZ file over the Internet, and when others decompress it, it comes out as a generic "document" icon instead of the proper kind of file.
- Easy-BZ currently stores Mac OS type/creator information in the comments field of a file. Several popular utilities fail to retain the comments field when transferring files over the Internet-for example, Hotline will replace the comments field with the name of the server that the file was downloaded from. The type/creator can be easily restored with any decent file editing utility-if you are looking for one, I highly recommend "FileBuddy."

About the Author

Easy-BZ was written by John Stiles, who also maintains a web site called and ports several emulators to the Macintosh. Easy-GZ was originally designed as a ROM compression tool for emulators, but quickly grew in scope as the project progressed.

Easy-BZ is freeware; please distribute it however you wish.
