I have a 180GByt SSD in my laptop, which is full, i.e. less than 100MByte left .. . after

… after relocating 10GByte of user-data to an external NAS, I had 2GByte free memory space left on that SSD.

I am a bit surprised about what’s going on there.

Yes, I did not do anything else, e.g. de-compress stored data, or any similar activity.

My expectation was that after relocating 10GByte to the NAS I would have a spare capacity of 10Gbyte.

Any HDD would do that.

I am curious about the reasoning


if you moved 10GB of data 10 GB should be free. you can use a program like spacesniffer to see what data you ahve on the drive and where it is stored.
