Here's some info: > http://linux.about.com/od/commands/l/blcmdl1_zip.htm You can also use a password protected dmg for secretive purposes without need of Terminal. 1. Open Disk Utility 2. File/Open/New/[choices] and make a choice in [choices] 3. And in a dialog box that comes up, you choose name of what is to be saved and importantly "compressed" and then choose encryption and a hit return. 4. Read very carefully and make special effort to note the guide in the further "Enter a password" that secures the compressed image. I use it to keep the recipe for how to cook my enemies (for maximum flavour). -- dorayme

Agree. : ) -- Send responses to the relevant news group rather than email to me. E-mail sent to this address may be devoured by my very hungry SPAM filter. Due to Google's refusal to prevent spammers from posting messages through their servers, I often ignore posts from Google Groups. Use a real news client if you want me to see your posts. JR

Here's some info: > http://linux.about.com/od/commands/l/blcmdl1_zip.htm The man page for zip says that the encryption method it uses is "considered weak", and so I wouldn't trust it for data that is truly sensitive. -- K.

GUI Tar is an excellent FREE frontend app to many compression methods. <http://www.edenwaith.com/products/guitar/> "GUI Tar is a wrapper application which acts as the front end to the 7za, tar, gzip, bzip2, uncompress, unrar, unzip, and zip UNIX utilities. The operating system itself handles the complicated work, while GUI Tar provides a pleasant and easy method to interact with these system tools. GUI Tar is divided into two sections: Extractor and Compressor. "GUI Tar Extractor offers the functionality to uncompress and extract files from archives. The following files can be opened by Extractor: ..7z, .tar, .tgz, .tar.gz, .dmg.gz, .svgz, .gz, .tar.z, .z, .Z, .tar.Z, ..taz, .tbz, .tbz2, .bz, .bz2, .rar, and .zip. "GUI Tar Compressor can compress and/or archive a collection of files in ..7z, .bz2, .tar, .tbz, .tgz, .gz, .Z, or .zip formats. Archive files and folders from multiple locations, instead of being restricted to just one directory." |
