Reduce File Headers? Is 52.9% Normal ?

Hello guys,

I have been wondering if my game has a healthy File Headers size. ~53% sounds too much
but on the other hand my game contains about 20 different scenes.


Textures 119.2 mb 23.1%
Meshes 10.4 mb 2.0%
Animations 7.3 mb 1.4%
Sounds 12.1 mb 2.3%
Shaders 6.2 mb 1.2%
Other Assets 5.4 mb 1.0%
Levels 73.8 mb 14.3%
Scripts 1.9 mb 0.4%
Included DLLs 6.4 mb 1.2%
File headers 273.2 mb 52.9%
Complete size 516.0 mb 100.0%


Can anyone tell me if that is normal or is the File headers too high?
Also how on earth can I reduce it?

I've been experementing for hours but I cannot find anything that is causing it.



Thanks for any help

 

Did you get anywhere on this? I'm in a similar boat:

Textures 186.6 mb 21.7%
Meshes 52.8 mb 6.1%
Animations 5.7 mb 0.7%
Sounds 4.0 mb 0.5%
Shaders 2.5 mb 0.3%
Other Assets 3.1 mb 0.4%
Levels 38.0 mb 4.4%
Scripts 1.5 mb 0.2%
Included DLLs 5.1 mb 0.6%
File headers 561.6 mb 65.2%
Complete size 860.9 mb 100.0%

Reading around there seems to be a claim that the file headers size is associated with the Resources folder, but mine is only 15MB on disk for about 200 items, and plugins' Resources folder total around 5MB. I even went to the effort of putting all the contents in an Asset Bundle instead (and thus had no Assets/Resources folder) and that reduced Textures and other specific items, but file headers was unchanged.

FYI I am using Unity 5.4.3f1 and building for iOS

 

Apparently "File headers" can also be where lighting data is stored. I made some changes to the lighting in a scene, which removed it's baked lighting data and decreased it's precomputed GI data, and the "File headers" line decreased comparatively (around 140MB decrease).

 

yes, I came up with the same solution, sorry for answering late.

You have to uncheck the Precomputer RealtimeGI. Though this will little reduce the beauty of Lightning but the amount of Space cannot justify it.


for me the file headers even went down to almost 0%. (i saved almost 270 MByte of uncompressed junk data)
I think it's about ~1% but I am building for Android and I am not using any Resource Folder name

 

Hi guys, this is my first time adding a comment here since i'm new to unity

I'd also experience having almost 70% of my project that is allocated to file headers

Textures 5.4 mb 1.4%
Meshes 13.0 mb 3.3%
Animations 2.3 mb 0.6%
Sounds 2.4 mb 0.6%
Shaders 9.1 mb 2.3%
Other Assets 22.5 mb 5.7%
Levels 45.6 mb 11.6%
Scripts 1.5 mb 0.4%
Included DLLs 13.3 mb 3.4%
File headers 278.2 mb 70.7%
Total User Assets 393.2 mb 100.0%
Complete build size 861.7 mb

First i didn't know what the problem caused of decreasing the file headers since my later build, the file headers was just about 300kb, by the way before the file headers increase, i'm just searching around how to optimize my game then I just realized that it happened when I did set all my object to Static, so i just unchecked the checkbox and turn it all to dynamic but the problem is, the game is now laggy again, and and the fps were around 5

Yes, @kk99 solution worked for me aswell. Uncheck realtime global illumination from the lighting scene settings!
