In Disk C: Defragmentation level 26%

Shenal123

Hi,
I have aspire 5 and in acer care center for disk C it shows Defragmentation level is 26% and attention required. Can I please know why is that and how can I solve that please.
Thank you.

There are some bugs in acer care centre so, you can't do it from this software.
Do it manually, follow these steps→

Optimizing your drives can help your PC run smoother and boot up faster. To optimize them:

• Select the search bar on the taskbar and enter defrag.

• Select Defragment and Optimize Drives.

  

• Select the disk drive you want to optimize.

• Select the Optimize button.

Adding to what @GAMING6698 said, I'll try to explain what fragmentation is with book collections.

Say you have a long saga that spans 20 volumes for example, you have put them in a book drawer among many other books all in the same spot. Over time, people seem to get books and place them somewhere else after they're done reading them, or maybe the saga has grown and instead of putting #21 next to #20 put put it in the first empty spot.

That's what fragmentation is, but instead of books it's files. Files are written to disks in chunks and when those chunks aren't together reading a file (in the analogy, reading the whole saga) is slower because the disk heads have to move all around to get all of the chunks.

What defragmentation does, "Optimize" in terms of the Windows utilities, is bringing all of those chunks together again; getting all of the saga in the same spot of the bookshelf. It may take a while, so when you click "Optimize" you may go do something else; but you'll see an improvement in access times later on (or responsivenes, depends on the degree of fragmentation).

On SSDs it isn't that important because access times are independent of the position in the disk, but mechanical hard drives (what I think you may have) do suffer from it.
