Creates a new Entry in the Zip file and adds the content of the inputstream to it. This method wont work in threaded mode and will execute in the same thread, not in a different thread as most of other methods. This is a reason that _Progress Event will not be fired using this method, if you use it you need to ensure your application wait until the stream finish before the systen can access to the written file. Zip file may not necessary exist. If Zip file exist, then the InputStream will be added to it. If Zip file does not exist, then a new Zip file is created with the InputStream content. Notes: Standard zip encryption cannot be used with this functionality unless you know CRC of the stream to be added in advance. If this is the case, then this CRC has to be set in ZipParameters.setSourceFileCRC(int) before calling ZipFile.addStream() method. There are no limitations for AES encryption. ZipPath: Specify the Zip file Path (eg. "C:\DestFolder\MyZipFile.zip") FileNameInZip: This would be the name of the file for this entry in the zip file (eg.

Add a folder (void or with content) in the given path to the Zip file. Zip file may not necessary exist. If Zip file exist, then this folder will be added to it. If Zip file does not exist, then a new Zip file will be created with the folder mentioned inside it. ZipPath: Specify the Zip file Path (eg. "C:\DestFolder\MyZipFile.zip") ZipFolderName: Specify the name of folder to add to Zip file (eg. "C:\FolderToAdd") CompressionMethod: Specify compression method constant (eg.

Add files to Zip file with AES Encryption. (Don't work with Asset Files) Zip file may not necessary exist. If Zip file exist, then these files will be added to it.
