From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't think you can shrink an active partition, especially if you're booted from it. Just use gparted live, it's fine. I prefer doing all my resizes offline. The only thing I do online is extending.
I thought so too, but apparently you can. I saw people on youtube do it on their active C partition
Can confirm that this (should) work, done it multiple times.
Huh, they must have changed that at some point. Last time I checked (which was probably many years ago at this point) they didn't support it. I've just always used tools like gparted because I got used to them.
It's kind of hit or miss. Depending on how full the partition is and how exactly the data is arranged, windows may not be able to shrink even a non-boot partition.
The built-in partition manager doesn't seem to be capable of rearranging anything, so you kind of just have to rely on luck for the shrink operation to be possible.
Hence why third party tools like easus are still in business on the windows side.
Defragging works for that.
I seem to remember disabling hibernation and swapfile, then defragging, seemed to significantly increase the chances of success shrinking an active partition.
(Re-enable hibernation/swap after the shrink operation is finished.)
But is that still recommended on an ssd? Defragging for higher success of shrinking an active partition?
Definitely don't defrag regularly because, yes, it will wear out the SSD. However, defragging once will move the files into a contiguous chunk of the partition and allow you greater success at shrinking it.
weirdly enough I feel the same. Maybe those were the WinXP times
Had to do this on Win11, it worked.
I shrunk my Win10 partition from within Windows to make space to dual boot into linux so you definitely can shrink an active partition.
@dysprosium @catloaf GParted takes a lot of time doing tasks. Is this normal?
depends heavily on amount of data and cpu speed. I wouldn't wanna interrupt though
And hdd/ssd speed. Honestly it's more about the drive speed than the cpu.
Yup. If data has to be moved, that's one read and one write, in different parts of the disk. That's going to be slow. (At least they'd be sequential, I think.)
Depends on the task and the hardware. Disk operations can be anywhere between instant and hours.
In some cases, days. When I last retired some drives in my NAS, the task of moving the partitions onto new drives was a 48 hour process.
Like already said, unless you're sure something has gone wrong, don't interrupt. As long as it's still doing its thing, it'll get there.
