The Archive Browser is a program that lets you browse the contents of archives, as well as extract them. It will let you open files from inside archives, and lets you preview them using Quick Look.
It is based on The Unarchiver, which means it can handle a large number of different archive formats: It can handle common formats like Zip, RAR, 7-zip, Tar, Gzip and Bzip2, as well as older formats like StuffIt, DiskDoubler, LZH, ARJ and ARC. It can also handle other kinds of formats, like CD and DVD images such as ISO, BIN, MDF, NRG and CDI, many Windows self-extracting EXE files, and can even extract media from Flash SWF files and images from PDF files. See the supported formats page for a full list.
It will also handle different filename encodings gracefully, and for the curious, it will show a lot of information about the archives and their contents.
Try it for free for thirty days by downloading it from the link above. Once you have a license, you can always get updates by downloading the trial version, it will use your previous license to active itself.
You can also get The Archive Browser from the Mac App Store, but this is not recommended. App Store apps are sandboxed, and this prevents several features of The Archive Browser from working properly. However, if you still prefer the safety of the Mac App Store, click below.
If you have any trouble with The Archive Browser, please file a bug on the bug tracker, or post a question in the support thread.
