Question: How do I unzip a self-extracting file received by E-mail or on disk?

Answer: Occasionally, files that are sent via E-mail or on disk are self-extracting. This means that the file will unzip and install itself following different process than a non-self extracting file. The following instructions will run you through the steps that must be followed to assure that the files are installed correctly and into the correct drive.

When you receive a file that requires unzipping, it will have an extension of ZIP (Ex. chaps.zip) Simply double click on the filename and the unzip process will begin. If the file is self-extracting, the first message will look similar to the one below.

Click on “OK” to proceed with the unzipping process. WinZip will then open a screen that will look similar to the one below.

In the “Unzip to folder” field, fill in the location where your CHAPS files are located. (most commonly, C:\Program Files\CHAPS) or browse for the location by clicking on the “Browse” button. A screen similar to the one below will appear to assist you.

Once you have located the correct directory, click on the “Unzip” button and WinZip will finish the unzip process. Once the file or files are unzipped and saved into the specified directory, the message shown below will appear. Click on “OK” to finish.

You can then close out of the WinZip program. If you wish, you can then check the directory to verify the new file was installed.
