Answer:
They had to unzip or extract the zipped/ compressed presentation to see it.
Explanation:
- Compressed file or a zip file contains a large file or more than one files that are packed or enclosed that large file or several files into a file or a folder.
- The compressed file or folder takes less space than the actual large file or set of files.
- Just as in this scenario the presentation file was larger than the size of what an email file should be. So Tikenya had to compress the file in order to email it to other members.
- The other members can open the PowerPoint presentation by following any of the below mentioned methods:
- In Windows to open a compressed file, right click on that file and select Extract All option.
- File can also be seen by opening that file or folder and dragging that file or folder from the zipped folder to a new location. In Windows this will automatically extract the files.
- This file can also be opened using a software like WinZip. Download WinZip. Then download the file which is sent in email and double click on that file which will open WinZip wizard dialogue box. Clicking that presentation file from the dialogue box will open another dialogue box confirming the opening of that file. By clicking on OK the presentation file will be opened and can be viewed now.
