What the file extensions mean (.gz, .tar, .tar.gz, .tgz, .E00)
The .gz file extension indicates the the file is in a compressed (or zipped) format. Files with the .gz extension can be uncompressed using the gzip utility.
The .tar file extension indicates that the file is an archive that has been put into "Tape ARchive" format. Today tar is most commonly used to package files together for transfer over the internet. One tar file usually corresponds to many regular files. Files can be extracted from the archive using the tar utility.
The .tar.gz file extension indicates that the file is in gzipped tar format (both archived and compressed).
The .tgz file extension (or sometimes fname_tar.gz where fname is the actual file name) also indicates that the file is in gzipped tar format. This extension may be used if the creator wanted to limit the file extension to three characters.
The .E00 file extension indicates that the file is in ARC/INFO export format. This file type can be directly imported into ARC/INFO.
How to use WinZip® (shareware Windows version of tar and gzip utilities)
Once you have downloaded the compressed file double click on it. This will launch the WinZip® program. Select "Yes" to decompress fname.tar (where fname is your actual file name) to a temporary file and open it. Next click extract on the WinZip® toolbar. Make a note of the location that you are extracting to and click "Extract." WinZip® will now extract your files into the selected directory.
