I fixed the bug, i have an empty acf manifest for unknown reasons in one of my libraries (Rust AppID: 252490).

Thank you very much. I added one more commit. I don't know whether the file size of the acf file is actually 0. Could you please check whether my last commit breaks the fix? 1da559116c5ba6a56ce6e14460dd5e884050d950

No problem :), based on your code i just read, it will work , I will test ASAP.

@akorb

Works only for the empty file bug, see #9 i added a check for NULL bytes corrupted files also.

[akorb]

Thank you very much. I think about adding some tests. Could you attach the acf file please? I guess that's a good step to start

Hi ! :) Nice idea about tests suite.

I attached the file (renamed to .acf.txt due to github files policy)

appmanifest_252490.acf.txt

Thank you very much. I added your commit with some changes. 6e4026e7631e8fd8c8ab406a4b4e08e7a804dd9f

I will publish a new release next week
