Tip: Reduce Session file.

Hi, just a quicky i found out. If you have a big session file like me (18GB O.o)

it might be worth turning on NTFS drive compression, especially on a SSD.
It reduced the file for me to 3.5GB, thats quite significant!

Perhaps an idea for WM to compress the session file with a simple compression algorithm or give an option for it ?

That’s definitely worth noting.

I should mention there’s a dev branch that has enabled fast LZ4 compression of the session and temp files. This is not of much use for typical heightfields, but does work well for masks (they often have large expanses of constant areas). It does no harm and does improve space usage, so it will be merged into the dev channel sooner or later.
