Browser upload and download limits

Hi,

Some time ago, I attempted to upload a large, 3GB I think, file to a file storage site.

I waited quite a while as the file uploaded; America really doesn't have high speed internet as you all know.

But, right around the 2GB mark I got an error message about exceeding my browser's limit and the uploading stopped altogether with whatever was uploaded lost.

Why did this happen?

I've gotten this error when downloading large files as well.

Am I to assume that internet browsers use RAM as some kind of buffer when uploading and downloading and that if files are too big RAM gets exceeded?
 
Tell us more information-what browser, what OS, which storage site, the source of the message and its exact wording.
 
There is no browser that I am aware of that would download everything to RAM first.
Usually, you see that message if you have a filesystem that doesn't support >X GB files.

Or in other words, don't try to get a file that is bigger than what the filesystem can support, or it won't be able to write it. (Very common if you use a FAT/32 USB stick to download stuff to).

I was uploading data.
 
I tested uploading a file to Mega.nz and used packet analyzer, each data frame is only about 3000 bytes.

Like what Elixer said, it's something else. Have you retried since then?

It was months ago. I managed a way around it, but can't remember what I did.
 
Well, just ignore it then. Since 2GB limit only happens on old FAT16 file system, and all new system file size limit is way beyond that.

Unless file storage sites set a hard limit, but checked mega.nz and it seems does not have file size limit.
 
When you send a file or data across ethernet cable or wifi connection, the file or data must be broken down to TCP data packets and transmitted from source to destination and recombined. They are usually among 1300 or 1500 bytes to 9000 bytes (jumbo frame).

It does not have to do with file size directly, of course. But since you are wondering whether the 2GB limit has anything to do with buffering, I'm just trying to explain that the file uploading / downloading big files doesn't mean browser will load the whole file in the memory before doing the transmission.

But how does the size of the frame pertain to file size limitations?

The number of frames seems pertinent here, not the size of the frames themselves.
 
Mega caches everything to temporary internet files as it uses some proprietary upload/download nonsense to do it's thing. I get the same thing when I try to do anything with mega if an individual filesize is larger than about 1.5 gigs, firefox will try it's best until the cache gets too big and it crashes.

Long story short, it's not the browser that's the "problem" really, Mega is just trying to do things in a way that is unreasonable for a browser to do. You can use their Megasync app if you really want to get around it, but since they put download caps on free users and started pushing this crapware I've just stopped using them entirely. The only good thing about them *was* the lack of an hourly download cap in the first place.
