When you see something weird like may zeroed files remember to check the final value displayed by quickbms: "coverage file 0 " followed by a percentage.
If that % is bigger than 95% then it's all ok.
Remember that the coverage depends by the format, in some formats you can have a coverage of 100% while in others even 70% (small file and lot of padding) and both are correct.
I'm not sure that I understand this completely after running a second test.
When unpacked seperately using New_Fear.bms, two files, hosted here
(sorry for size, they don't come smaller), will each produce an instance of the example file:
both have a size of 4.097 KB
However, when exported together, and hitting r
when prompted, the files will produce two files in the same location: Good old player_sword01_d.tex0 and a second file player_sword01_d_00000001.tex0
The first has a size of 8.193 KB and the second has a size of 0 KB
Once again, sorry if I keep asking stupid questions, but I don't understand, is this the intended behaviour?
