How can I get copressed Texture Size

i read this thread (How can I tell the COMPRESSED size of assets in my streaming web player build? - Questions & Answers - Unity Discussions)

but size is wrong

I want get displayed size in preview window

(Left top is ‘original size’ 160k
Left bottom is Library/metadata cache file size’ 10k)

Size = width * height * bytes per pixel. PVRTC 4 bits is .5 bytes per pixel. Also multiply by 1.33333 if you have mipmaps on.

thanks for your replay

but I need get other copress asset(anim, sound, fbx…)

None of those get compressed by Unity, with the exception of meshes, but only if you turn on mesh optimization.
