'APPE': command unrecognized. (code=500)

Question

Hi there,
I come to you because I'm a little bit lost... I encounter this error when I try to upload a file to one of my FTP server, and I don't understand why. I use exactly the same code (moreover in the same application) to connect and upload in another FTp server.

'APPE': command unrecognized. (code=500)

Here you have the stack trace :

Answer 1

Seems that your FTP server doesn't support the APPE command, which is to append to an existing file.

Answer 2

Thank you for your answer... Previously I had the following line :

FTPConnexionGalerie.UploadFile(MyFile, MyFileOnFTP, true);

I remove the "append" argument, and it works.

Thank you !!!
