If you decrompress an Exalted Export file, open the folder, take out the .ecg file, put it in a new folder with the same name, and compress it, Anathema will not import the file

I was curious if I could get around Anathema's failure to import by re-compressing the files. It doesn't work, even for fresh exports (either Mac or PC). This leads me to think that you guys are doing something VERY sketchy with your files, in the sense of making them something that can survive being shuttled back and forth.

The ZIP-Format supports comments on zips content files.
Anathema uses that feature to identify the type of file during import.
I suppose your manually created zip doesn't have those comments, thus Anathema can't import them.

In case you would like to suggest doing it differently: Yes, that is very possible and I can see no reason against it. I'd gladly take a pull request if someone came up with one.
