Why does Android aapt remove .gz file extension of assets?

问题

When I add a GZIP-ed file to my Android project's assets, the ".gz" extension is stripped when the project is packaged. (So, for instance, "foo.gz" in my assets folder needs to be accessed in code using getAssets().open("foo").) This doesn't seem to happen with other extensions (e.g., ".html") that I'm using. The asset is still GZIP-ed (I have to wrap the input stream in a GZIPInputStream to read it).

Is this standard behavior or a bug? If it's standard, is there any documentation about which extensions are stripped and which are preserved?

EDIT: I misstated things sightly. I'm experiencing this problem with the Eclipse plug-in. I haven't tried running aapt directly to see if the problem is with the tool itself or with how the plug-in is using it.

var globExp = path.resolve(__dirname, '../../www/lib') + '/**/*.gz';
deleteFilesFromFolder(globExp);
