@adriansev : sorry for the delay! The issue should be fix now with following commits: 04eb74a15857d62520e3a2cbc3260beca6684c51, 11f4ef78709c9b81d0b13e629125348eaf96c1aa and 3011213e3ee6a71bba1958ca7d5f6928f5c31c4b There were actually two problems: - the client was not correctly handling the `data descriptor` record present at the end of file - this particular example is a corner case where the compressed size is slightly bigger then the uncompressed size: ``` zipinfo -v 66b0b4b0-c27c-11e8-82d6-626f12b4f71d ... Central directory entry #4: --------------------------- There are an extra 16 bytes preceding this file.
