Resume / cancel cause corrupt the zip file

[MohammedAlam]

Hi Filad, We are using this html5uploader. Recently we found some file corrupt (zip file) after upload. The corrupt occur when we cancel(it resume and next time if we upload same file) it start adding with the existing partially uploaded file. In server when we unzip it it show corrut. But if we upload a file in a go (no resume/cancel) it works fine.

Do you any any idea why it happen & any solution? Just want to know , when we cancel, is it deleted the partially uploaded chunk part? example we have 5 chunk of a file 1 , 2, 3, 4, 5. At the stage of uploading 3rd chunk, I click cancel. It may be upload like 2.5 (half of the 3rd chunk) So in the cancel click it will remove 3 chunk ? or it will keep upto 2.5 and next time it will start from 2.5?

Sorry if I descreption make complex. I try to explain .

Thanks Mohammed
