- Reduces the size of files.
- Lossy Compression
- Reduces the size of data by deleting some of said data.
- Lossless Compression
- Reduces size without loss of any data.
- Defragmentation software
- Re-organises files by putting related peices of data back together, so few disc accesses are required. Improves performance and free disc space
- Backup
- Copying files to a secondary storage, such as a disc or cloud service.
- Full Backup
- All of the specified data is backed up
- Incremental Backup
- Untitled
- A collection of tools which do specific jobs. Helps configuration, analysis ond optimisation of the system.
