Files you download from the Internet are often compressed or zipped so that they take up less space and arrive much faster than files that haven’t been compressed. You can easily identify compressed files by their extensions, such as .zip (a common standard used in OS X and Windows) and .sit. Before you can use these files, you must learn how to unzip files on mac computers for proper access – luckily the process isn’t that complicated!
How to unzip files on mac computers
Unzipping a file on a mac computer is user-friendly and intuitive. To unzip files on a mac, simply follow the steps below:
- Double click the zipped file.
- The file will automatically be decompressed by Archive Utility into the same folder the compressed file is in.
- Access the extracted files by clicking the appropriate icons.
Alternatively, if the method above does not work, you can right-click on the .zip package, and select Open With > Archive Utility (default).
Apple and third party software
Apple used to include a program called StuffIt Expander to decompress zipped files, but doesn’t now that OS X lets you unzip files (but not .sit files). However, StuffIt from SmithMicro Software still comes in handy for opening other types of compressed files, notably the .sit or .sitx compressed types. Go to www.stuffit-expander.com or www.stuffit.com/mac/index.html to download a free version of the software or to splurge for the Deluxe version. In addition to compressing files, StuffIt Deluxe lets you encrypt and back up files.
Meanwhile, you can archive or create your own .zip files through OS X, which is useful if you’re e-mailing a number of meaty files to a friend. Right-click (or Ctrl-click) files you want to compress inside Finder and choose Compress Filename. The newly compressed files carry the .zip extension. The archive is created in the same location as the original file and is named originalfilename.zip. You can also choose File→Compress. If you compress a lot of files at once, the archive takes the name Archive.zip.
By default, compressed files are opened with the Archive Utility. It appears in the Dock (in Leopard) while the files are being unsqueezed, unless you choose to open them with Stuffit Expander or some other program.

On the flip side, you can also archive or create your own .zip files through OS X, which is useful if you’re e-mailing a number of meaty files to a client or friend. Follow the step-by-step instructions below to easily zip files on a mac:
- Right-click or Ctrl-click the multiple files you want to compress (whether on the desktop or inside the Finder).
- Select Compress Filename from the pop-up menu.
- The files are now compressed in a .zip extension and the archive is created in the same location as the original file name, except with the .zip appended to its name.

http://windows.microsoft.com/en-US/windows-vista/Tips-for-solving-problems-with-USB-devicesyou sat i can find it, how? is it in disk management? - If this is a portable drive (no separate power supply), then this may be a power issue. Portable hard drives require a fair bit of power, and while they SHOULD fall within the USB specs (500mA for USB 2.0), some demand a little more. Equally, some hosts (computers, TVs etc) provide just a little below spec, so sometimes you get a bad combination.
To test this theory, try the HD on a number of different USB ports on different computers (not just your PC & Mac) and see if they can be read on any of them. If this is indeed the problem, and none of the ports on your computers provide enough power, then there are two things you can do: 1) get a USB 'Y' cable which will aggregate the power from two different sockets or 2) use an external power supply if your HD has a socket for one (if it does not, you may be able to obtain another HD enclosure, which does have such a connection, and transfer the drive itself to it.
