使用7-ZIP吧，相隔快一年，作者終於推出4.0版了，雖然是beta版
不過引頸期盼的功能終於加上去了，但Splitting to volumes這功能有點像是在騙人
大夥比較想要的是SFX multivolume archives

7-Zip 4.07 beta
4.07:
4 - 2004
07 - revision number, 01, ..., 06 were used in LZMA SDK.

Changes:
- Big amount of code was changed in this beta version.
So don't use it for important data compressing.
And test archive after compressing.

- Unified command line interface to GUI and console versions
- 7-Zip now can extract or test several archives in one command
- 7-Zip now doesn't interrupt the compressing when file is locked by
other application. 7-zip just skips that file and show warning.
Note: previous versions of 7-Zip had bug, so they can not unpack
non-solid and some solid 7z archives with such skipped files.
- Command line interface was changed:
- now it's possible to use absolute pathnames
- syntax simplification:
was: 7z a a Folder1\* Folder2\* -r
now: 7z a a Folder1 Folder2
- now it's possible to use complex wildcard commands, like *\*111*\*
- More smart detection of archive type for files with unusual
file name extensions
- Supporting for RAR archives with encrypted headers
- CPIO format supporting was improved
- For GZip and BZip2 formats you can:
- Compress from stdin (-si switch)
- Compress to stdout (-so switch)
- Extract to stdout (-so switch)
- 7-Zip File Manager:
- Split and Combine commands
- new list view options: Full row select, Show grid lines
- Internal reconstruction
- Some bugs were fixed
- New localizations: Friulian, Macedonian, Mongolian, Tamil, Thai
