@TheJamsh, thanks for explaining. TGA is 0% compression, I’m a developer then I know that its format is a binary like this: RGB(255, 128, 0) = 0xFF8000, and the TGA file is stored exactly like that, there is no compression, that’s why it’s sooooooo biiiiiiiiiiiiiiig, and saying “TGA is better” is same as saying “BMP is better” because TGA is a BMP with alpha version.
So my conclusion is we are living in an imperfect world, many programs are terrible when store PNG, and it seems forever, there will never be a PNG2 because everything depends on the programs. TGA is 0% compression as I explained before, that’s why it never occur a problem on alpha. … It’s so sad to know that the world is imperfect.
My laptop’s hard drive is 1 TB, but I have to split it into 2 partitions (C: 300 GB and D: 700 GB) and 700 GB is small. And the worst thing is I have three 500 GB external hard drives, each one is smaller than 700 GB that I backup into the external hard drives.
