Imagine blocks of different shapes and sizes which are your files on your computer. But your computer only has a certain amount of space to store these blocks. Disk compression is like a magic tool that can help you make more space for these blocks by squeezing them together so that they take up less room.
It's like when you put your clothes in a suitcase before travelling. You fold your clothes very tightly, you roll them up, and you stuff them in as tightly as you can. You're compressing your clothes to take up less space in the suitcase so that everything can fit. The same goes for disk compression on your computer.
Disk compression works by taking your files and compressing them into smaller sizes that take up less space on your computer. When you need to access the compressed files, the compression tool will quickly uncompress them so you can read, edit or use them.
Disk compression also helps your computer run faster since it has to read and write less data from the hard disk drive which reduces the waiting time for your files to be loaded. Plus, it also saves you money from buying new hard drives or external memory devices.
So, to sum up, disk compression is like a magic tool that can help you save storage space on your computer by making your files smaller while still keeping them accessible to you whenever you need them.
