Error in extraction

[felicegiovinazzo]

Hi, i have an error in extraction in the following code snippets

code:
var clfolder = Ti.Filesystem.getFile(clienteDirPath);
var f = Ti.Filesystem.getFile(clienteDirPath, 'tmp.zip');
var extractor = require('com.websiteburo.androzip');
extractor.extract(f.nativePath, clfolder.nativePath);

error:
Message: Uncaught Error: Size mismatch
Source: extractor.extract(f.nativePath, clfolder.nativePath);

This occours after the extraction of the first of 14 files in the zip top-level folder.
