Question:

FTP PutFile 100% before Upload is finished?! (c#)

Nov 27 '13 at 10:41

Hi everyone.

I am trying to uload a file to a ftp server. No TSL/SSL. Passive & Binary mode activated. The file is about 4.8mb and the format is ZIP, containing a TIF file.

When I try to upload this to my local server running on my own PC, it works fine. But when I try to upload it to the actual server, it doesn't work at all. PutFile returns success & the event shows 100% even though the file hasn't been uploaded completely. The size of the uploaded file differs between 1mb and 4mb.

Are there any parameters I could try to improve the upload? Right now I am using: passive=true, SendBufferSize=1024, and I use SetTypeBinary().

Do you now anything that could fix it?

Answer

try sendbuffer to 32787.

also receive, do not know if makes a difference, I set both.

Answer

success will be false, after percent reaches 100%. But the upload is not complete, just a few KB / MB are uploaded.

When success is false, the my thread will be closed but the upload will continue in the background. Why does it not stop when success == false?

changing the sendbuffer didn't change anything...

Answer

Try larger size, this is what I use on all transfers.

FTPBUFFERSENDSIZE=262144 FTPBUFFERRECIEVESIZE=262144

I have gotten the same kind of issues on some of my transfers.

Also with out the set buffer, transfers would take 3 hours, and they now take 20 minutes.
