Bookshare zip files don't uncompress

[ivanlabsii]

Bookshare is a service that distribute books in .zip files (DAISY format). Those files cause the following exception with method Ionic.Zip.ZipFile:

Ionic.Zip.ZipException: Could not read {local file path} as a zip file ---> Ionic.Zip.ZipException: Cannot read that as a ZipFile ---> Ionic.Zip.BadReadException:   Bad signature (0x20202020) at position  0x00000000

I can send you a sample for testing on email (they don't make the test files available for the general public), or you can get it by registering to: http://developer.bookshare.org, then find test credentials and available books for test here (after you sign in): http://developer.bookshare.org/docs/read/Bookshare_Test_Data_for_Partners, and then log in to Bookshare and download the book (this link will lead you to one that is available for download for tests: https://www.bookshare.org/search?keyword=Bookshare+Demo%3A+The+Rocket+Boys+of+NIH).
