File doesn't write to disk before download completes 3.0.7.1

While downloading on Windows Vista with client 3.0.7.1(3.0.3 also tried), the size of the file on my harddisk is alway 0 before completion. And if connection is closed or I manually stop the queue, the file just disappears! Thus I can't resume the download and always start from the beginning.

However, it's normal on Windows Xp with the same client version. I wonder if it's of incompatibility between filezilla client and vista. Thank you.

Where do you downloading to? And what type of File? Many folders in Vista are protected by the Virtual store.

%AppData%\Local\VirtualStore

I'm afraid it's not like that. I am downloading a binary file (actuall .rar) to a normal data folder. It's on a seperate partition from the %window_dir%'s or that for applications. Oh, it's a shared folder, but does it matter?
Later I tried flashfxp, found that the file size was also 0 during the transfer, but normal while I stopped the download.

I'll try different folder later, stay tuned...

It is quite normal this way. As long as the download is running, the file is exclusively held open, means Windows can't update the size information. When the file is closed, the information is updated (size, attributes, security information, time stamps).

At least on my system I have no problems opening files for reading during transfer.

@botg: Using Linux?

Linux, OS X and even Windows.

Well there is more than one type to open a file. If it's open for exclusive access, no other process can read or write to it (see your paging file for example). A file opened for shared access can at least be read by other processes (logfiles or similar).

Thanks boco for the explanation. So I think the title for this issue should be changed to "filezilla client doesn't close the file properly on vista while transfer is interrupted". I wonder if anyone else has the same problem like me.

So the file is left open and locked? That shouldn't happen indeed. Do you get the 'file sharing violation' when trying to access it? Can you resume the transfer?

sherlockq · #11 Post by **sherlockq** » 2008-02-24 08:53

Well, the truth is that:
1.file size always 0 while in transfer (it's normal, then)
2.file disappeared when transfer manually or abnormally interrupted, yeah, DISAPPEARED =,= (so, no possibility to access it, no chance to resume it)

weird as it sounds...

Shall I provide some debug info to you? I think this issue could be easily reproduced if it's due to a incompability on Vista Platform. But while it looks like only me met this issue. Does anyone running vista HAVE or NOT HAVE the problem?

Do you use any virus scanners? What happens if you uninstall them?

sherlockq · #13 Post by **sherlockq** » 2008-02-27 05:46

Only a vista built-in trojan scanner installed...I can't remember its name.

I'll try again after uninstall it.

Vista built in trojan scanner = Windows Defender.

i have the same problem using both vista and windows server 2008
i cannot resume any download and even it'll restart the download(no ask, i've setted "ask for action") every time it retries when lose connection
this means almost no large files could finish downloading, we're very upset to find this after wasting lots of time

and WHY MY POST HAVEN'T BEEN ANSWERED YET?
http://forum.filezilla-project.org/view ... f=2&t=5924
i've waiting for a long long time for your consideration of this issue, and tried 3.0.8.1, but it still exists
i've been using filezilla for 3 years and i prefer it to any other program. but i'm forced to use flashfxp now for downloading a number of hd videos. i'm eager to see filezilla could work and back to use it

PLZ TAKE IT INTO ACCOUNT, THANKS

other ftp programs, like flashfxp, work properly
