I am raring up files and downloading them via HTTP from my webserver. Most of the files have been below 2GB but now it seems the ones that are round 2GB and higher aren't working.

When I download the smaller files using Firefox or DownloadThemAll, the download manager detects the file size and states something like 3Mb/1.8GB. I can also pause and resume the download.

However, when I try this with files larger than 2GB, it does not detect the file size, but simply states something like 3MB downloaded and also I can not pause the download. After a while the download just fails.

I don't know if file size is the issue here. If not what is the problem, and more importantly - how do I get around it?

UPDATE:

The url looks like this: www.myserver.com:8600/dlfolder/images_2250_2499.rar

is there any http proxy between you and the server? –  petrus Nov 9 '11 at 20:58
    
@petrus: No proxy. –  Cheeky Nov 9 '11 at 21:08
    
Is the problem only with firefox, what happens when you download with IE/Chrome/Curl/Wget? –  Zoredache Nov 9 '11 at 21:09

Sounds like you have an old version of Firefox or Apache. According to bugzilla, this was fixed in 3.5. Apache fixed this in 2.1.

Update your software and you should be fine.

The question was updated, suggesting this applies to other browsers. –  Zoredache Nov 9 '11 at 22:00

It seems that you are using a workstation with FAT32. This is a limitation of this filesystem. Convert your fs to NTFS with CONVERT C: /FS:NTFS. See: http://support.microsoft.com/kb/307881

That seems unlikely FAT has a max file size of ~4GB. –  Zoredache Nov 9 '11 at 21:59

Indeed the limitation is ~4GB. support.microsoft.com/kb/314463 –  Mircea Vutcovici Nov 9 '11 at 22:53
