Here's some code: content = new FileInputStream(myFile); POIFSFileSystem fs = new POIFSFileSystem(content); HSSFWorkbook workbook = new HSSFWorkbook(fs); //code hangs on this line. Does anyone have any ideas? Does HSSF just not support large files? What is the largest file size supported? Can I enable logging in HSSF to get more information? thanks, ------=_Part_193091_1642524.1157558622465--
