Description

I was exporting a large set of tagged images as ome-tiff in web, total size several GB, so that I could re-import into a new dataset since deep copies aren't possible in OMERO.

Traceback (most recent call last):
  File "./script", line 614, in <module>
    runScript()
  File "./script", line 599, in runScript
    fileAnnotation, message = batchImageExport(conn, scriptParams)
  File "./script", line 462, in batchImageExport
    compress(export_file, folder_name)
  File "./script", line 78, in compress
    zip_file.write(name, os.path.basename(name), zipfile.ZIP_DEFLATED)
  File "/usr/lib64/python2.6/zipfile.py", line 1030, in write
    self._writecheck(zinfo)
  File "/usr/lib64/python2.6/zipfile.py", line 998, in _writecheck
    raise LargeZipFile("Zipfile size would require ZIP64 extensions")
zipfile.LargeZipFile: Zipfile size would require ZIP64 extensions

Possible fix- enable zip64:
