    "Description": "Hi\n \nUsed Version: V1.9.1.5, build from 2010-02-26 05:30\n \nI try to extract files from a zip file (which was created with SharpZipLib by a customer) in a folder \n- I set the property 'FlattenFoldersOnExtract'\n-> The \"zipFile.Extract(path)\" / \"zipFile.ExtractAll(path)\" function extract the compressed files every time to the original full compressed path of the files. It ignores the default path which I pass to the extract functions.\nIt makes no difference if I set the property 'FlattenFoldersOnExtract' or not.\n \n* A sample file can be found in the attachment.\n \n \nMy workaround: I overwrite the filename with a new filename without any path information.\nBut this cannot be a solution I think.\n \n \nRegards,\nDemian",
