Detecting corrupted or damaged files

Hello everyone,

I made a web dynpro application that uses the class CL_ABAP_ZIP to upload ZIP files. I would like catch an error when the ZIP file is corrupted before using the method "load". Because this method dumps when the zip is corrupted. More precisely it dumps at this line :

<ext>-content = zip+offset(<ext>-compsize).

Any idea how to handle this ?

Thanks for your help.
