    "Description": "After placing some pdf files taken from database as stream into zip file and directing it as a stram too just into browser .... there is a problem with openinig a zip file with windows compressed folders or winrar ....\nit works fine in total commander. During winrar opening one can see 0 CRC sum of pdf files ....after changing a name of the file CRC is calculated and everything works great.\n \nIt looks like there is no CRC calculated in my routine.
