Downloading large files

melonhead · 08-30-2003, 11:52 AM

I'm using 2.1 b924 trying to d/l large (4gb+) from a BFTP site. However, the file remaining time is way, way too short (about 2 hours - 512 ADSL, I wish!) and after about 400-500mb it drops the connection and starts from the beginning again - this carry's on looping like this indefinatley. CuteFTP Pro (yuk!) works ok though - any ideas?

Ckeck your options to see if you have always overwrite when downloading. You need to make it always resume.

Thanks, but that was already set. Interestingly CuteFTP had got about 2.5gb of a 4.3gb file when I lost my connection. When i reconnected I tried Flash again, to see if it would autoresume where cute left off, but it prompted to overwrite the existing 2.5gb file with one of 195mb!!! It looks like it's not getting the filesize correctly - but since cute does i assume that it's an issue with flash and not BPFTP server?

look at your status log. do you see REST command before RETR.
does REST have correct file size of your existing file?

melonhead · 08-31-2003, 02:51 PM

I don't think that that's the issue - I was just trying to make the point that Flash doesn't like files of that size, regardless of how I try to get them down.

It does however report the correct size in the log when initalising the transfer - maybe it's a field length issue and Flash just can't handle numbers that large?

That is not the case, from the features page
Transfer files of all sizes, no 2gb/4gb size limit like some ftp clients.

Older versions of BPFTP did not support large files, Please verify that the version your using does indeed support large files.

Some ftp servers support large files but they are unable to resume them.

melonhead · 09-02-2003, 01:02 PM

i've been assured that if it's not the latest BPFT, then it is only a point release behind. That wouldn't explain why unCuteFTP Pro works fine though

bigstar · 09-04-2003, 09:19 AM

it would be most helpful if you could include a copy of the status text also issue a raw command "SIZE <Filename>" where filename is the large file

melonhead · 09-05-2003, 10:24 AM

ok here is the result from the raw list:

size drp-xxxxxxx.img
213 193048576

when I start the xfer it says that the time estimate is 2:40:00 @ 24kbs, after it has got 100% it carries on for a while with the time remaining at ??:??:??. The filesize reported through FlashFXP remote view pane is 4.18gb. the log is below, I aborted after leaving it looping overnight:

from the menu, Directory > View raw directory, now compare the file size listed to the size returned by the SIZE command, do they match?

I'm not clear as to why the error reports a reset connection.

Would it be possible to give me access to the server so that I could further investigate the problem.

melonhead · 09-05-2003, 12:51 PM

This is the ouput from the RAW dir

-rw-r--r-- 1 ftp ftp 4488015872 Jan 25 17:26 drp-XXXXXXX.img

i'm sorry but it's not my FTP site, so i'll have to get permission.

regards,

Tim

From what i'm seeing the SIZE command reports a different value then that of the raw listing.

As such BPFTP is not 100% capable of dealing with large files.

FlashFXP relies on the accuracy of the SIZE command reply, if this value is wrong FlashFXP can not reliably resume the file.

But cuteFTP dont work for me, not even internet explorer, i would be happy if someone solves it!

What exactly is your problem? In the previous posts the problem was caused by the FTP Server, it didn't fully support large files.
