Corrupt images and pdf with goldraccoon ftp-upload - ios

Question

I use GoldRaccoon for ftp-upload in my iOS-Application. The filetransfer works perfekt with txt-files up to many mb size. But images and pdf-files would be corrupted when they be uploaded.
There is no error and the upload seems to be successfull.
When i look into the iPad in the folder of the application (with iExplorer), there the files are good. Its also equal how big the size of the image is. Also its equal if it is a jpg or a png.
Also the files all existing when I start the upload.
