Download partial file (General questions)
by Mike Baker, Wednesday, October 29, 2008, 16:22 (5868 days ago)
What will happen if we attempt to download something that is partially uploaded by our customer? Will it not appear on the dirlist if the item is in progress?
TIA

Hi Mike,
File will appear immidiatelly when you start to transfer it to server.
One thing you can do to determine which file is still unfinished and which is finished. You can upload file to server using some extension. For example .filepart extension. Something like this: weonlydo.txt.filepart
When file is uploaded to server completely you can rename that file and remove .filepart extension from name of file. You can do that using wodFtpDLX Rename Method.

Thanks for the quick reply. What we're doing is downloading files that our customers put up on the FTP site. I'm writing a service that polls folders for incomming files. When the file is found we download it. What will happen if the customer starts uploading and my service starts downloading before it's done. Is there a DirItems(n) property that we can check to see if the file's locked or something?
TIA

Mike,
wodFtpDLX will download that file. I have checked with other clients and it's same.
Unfortunately we don't have such property that will check if file is uncompleted. I'm not sure that this option can be implemented at all.
One workaround is to list files in folder and wait some time (5-10 seconds) and list is again and compare size of files. If file size is same transfer is completed.
