When I download Quicktime files using Cyberduck, the downloaded files show as being totally empty, even though the files exist on the source machine. What might be causing this?

Is the file size reported as 0B in the browser? Please post a screenshot of the file from the browser window general tab of the Info (⌘-I) panel.

This is a failure of the DAV server returning the correct content length in the PROPFIND listing. We might workaround this with changes in ba7cecc and 92c1d16 if the server returns correct responses for PROPFIND requests against single files.

I am the author of this DAV server (!)...
The server of these files can not report the filesize during PROPFIND because it is not known at this point in time. The files get generated when somebody really wants to download them. (The files exist in a different format before and get generated upon request.) The filesize of quicktimes can not be calculated in advance before the generation. When the client issues a GET request, the server generates the file (temporarily) and sends it with a PUT answer, then of course with the correct size. This has worked perfectly for years with earlier versions of Cyberduck, at least until 4.2.1. Since 4.3.0 it doesn't say "Download fertig" anymore, instead it claims "Transfer unvollstaendig", although it looks ok. Since 4.4.2 it says "Download complete" although it only saves about 200kB - every time.

Please think about this again... Thank you!

Should I use a version of Cyberduck before version 4.2.1 to work around this problem? If so, can you please download the earlier version to me? Thanks.

Thank you. Do I need to get a software download from you with the update you did in 487648c? I am not understanding what I need to do to handle this problem.

Unfortunately, my Mac computer that I use Cyberduck on is not connected to the Internet. Can you please e-mail me the latest snapshot build?

Is there a phone number that I can reach you at? Can you please assist me in getting Cyberduck set up to work on my computer. I still am not able to get it to work. I have the same problem discussed above. I am using a Mac Book Pro with OS X version 10.6.8. I am using Quick Time version 10.0 (128). I do not have Perian software, as it apparently does not work with Quick Time version 10.0. When I download Quicktime files using Cyberduck, the downloaded files show as being totally empty, even though the files exist on the source machine. What might be causing this? And what should I do to handle it?
