Light.dat file in the working folder is 128GB is this normal?
Tonight I processed 400 Canon 5d MKIV RAW light frames of M31 in APP with ~ 84 darks, 33 bias, and 33 flat frames. While processing I watched the "Available HDD" drop from 294GB to ~164GB.
In the APP folder there was a .dat file that was a HUGE 128GB.
Just wanted to ask if this is normal?
As soon as processing finished the file disappeared and available HDD went back up to 294GB
I have 32GB ram, 16GB allocated to APP but my RAM usage went from 27% to 87% during processing which I thought was odd.
Is there a tool or calculation I can use to make sure I have enough free HDD space for processing if using lots of frames, per the above?
Usually APP tells you if you have enough space left for processing, but it does use quite a bit for processing especially with higher resolutions etc. You can divide the data up in smaller chunks if you want to limit the resources more, like doing 4x100 frames at a time and combining those 4 later.
