Hello, I try to use Directory addTree: The src directory I use containts jpeg file. addTree fails because FileKernel use a FileJpeg in InputStream and there is a input pb on this file. I try to add binary mode : base binary addTree: dest but it is the same result: input error. When I copy this file directly with binary mode, it is ok. addTree collect files/dirs to copy but dot not transmit the binary flag. Is it normal ? Directory home binary files first isBinary ==> false ! Should it be true ? Is there another, 'official', way to binary recursive copy ? I use Pharo on Windows plateform. a+ Vicnet -- View this message in context: http://n2.nabble.com/Rio-binary-mode-copy-not-keep-tp3571512p3571512.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
