- but they are almost as small as a floppy disk
3 situations where disk compression would be used
1. When copying a large file onto a floppy disk
Compressing the file might be the only way to get the file to fit onto a 1.44MB floppy disk.
Or you might want to put a lot of files onto one disk.
2. When sending an attachment via e-mail
Compressing the file and reducing the file size makes sending the file much quicker.
This reduced time spent on-line and saves money on the phone bill.
3. Compressing before backing up
If you are going to back up a lot of information then compressing your data will make the backup quicker. If backup media ( e.g. Floppy or tape drive ) is limited, then compression will make the most of your available backup storage.
Higher Level Notes
Compressed files are usually called Zip files, because they are effectively 'zipped' and reduced in size.
Zip files can be created by a number of different software packages - the most common one on the market is Iomega's WinZip - you can download it for free ( shareware version ) from the internet.
A compressed zip file can contain more than one ordinary file. The only limit is the amount of storage space that you have. A collection of many files in one zip file is usually called an 'archive'.
When you uncompress a file, you will need to use the software program that you used to compress the file. If you don't have this - you can't uncompress the file and your data may be lost.
With some compression software you can make a 'self-extracting' file. This is an EXE ( executable ) file that will automatically uncompress the compressed files without the need for compression software. This is used on the internet when you download the latest drivers - the drivers are in a self-extracting file to make the most of the company's web space. Anyone can uncompress it - even if they do not have compression software.
