hi, im new to linux and kubuntu, so i have a question. do i need any software that would maintain kubuntu, clean junk files, perform something similar to disk defragmentatiion in windows etc.?

Re: linux question

Short answer: no

You can "clean Junk files" with e.g. Bleachbit

Re: linux question

Welcome to the forums!

The need for defrag on Windows machines used to be a great joke in the Linux community. There is however a file check which runs automatically and doesn't need user intervention. What you'll really like is that often Linux runs faster after you've used it for a while.

Yes, yes, maybe not.

Clean up private information, and free up disk space...

A KDE cleaner:

There are many filesystems > File systems wiki.

Ubuntu default is the ext4 (at the moment) > Ext4

A link > Ext4 defragmentation with e4defrag:

For all who would like to say that Linux file systems don’t require defragmenting: Please redirect your great ideas to the Ext4 developers. They are the authors of this program — I do not have anything in common with it...

Second link > How to Defrag in Linux:

A common question from new Linux users is "How do you defrag your hard drive?" The short answer is that you probably don’t have to. The file system on Linux and other UNIX (and UNIX-like) operating systems is organized and stored more efficiently than the one on a Windows PC. On Windows, PC users will not notice a performance dropoff until fragmentation hits 20 percent or more, which is rare...

@ Rog131

As a child my eldest daughter "knew" how to ride a bicycle and therefore couldn't understand why she couldn't ride an bicycle. Difference between "knowing" and "doing".

Have you defragged Linux with a positive effect?

No, i have not defragged - Why not ?

Because:

The need of the defragmentation is rare:
> How to Defrag in Linux:

> File system fragmentation:

To summarize, factors that typically cause or facilitate fragmentation include:

• low free space.
• frequent deletion, truncation or extension of files.
• overuse of sparse files.

Here the partitions sdd3 (77% used) and sdd4 (91%) have 0.6% non-contiguous and 11.4% non-contiguous => I don't think that there are need to defrag...

...maintain kubuntu, clean junk files, perform something similar to disk defragmentatiion...

What i try to say: There are not maintance free systems - the Linux (Ubuntu) needs maintance. Even the disk defragmentation, if the user let the system slide without proper care.

Re: linux question

I'm not familiar with any defragging tools for Linux, but it's possible there is some obscure tool out there that I've not heard of. Having said that, I've been running Linux for about 11 years now and have never defragged a Linux filesystem.
