Which is the correct spelling of the word?

For example, "The file is not updat(e)able.".

Btw, I did go to google and ref.dic.com for this first, and they both seem to indicate that they are both correct. If they are indeed both correct, which is more widely accepted?

At the risk of being controversial, you just might want to consult a real dictionary about something like this. The OED gives only updatable, not the other one. – tchrist Jan 31 '12 at 16:50
I haven't even seen a real dictionary since grade school xD – Nick Rolando Jan 31 '12 at 17:26

Google Ngrams shows that updatable is currently much more prevalent:

Updateable vs Updatable

Never heard of Ngrams. That's pretty cool. Thanks. – Nick Rolando Jan 31 '12 at 1:04

You'll be in fine company either way. I looked thru some technical books online and found both widely benoted.

For me, updateable is the better choice but, as I said, either one is good.

Yeah. As seen in the graph in @Gnawnme's answer, it is used quite a bit! Only half as much as updatable though. – Nick Rolando Jan 31 '12 at 17:27
If yu look at an ngram comparing knowledgeable and knowledgable, yu'll get an even bigger gap yet both are acceptable spellings. I like updateable for two reasons: 1. upgrade > upgradeable therefore update > updateable 2. The a is ā (long), the 'e' keeps this ... updatable looks likes up-data-ble to me. We see this (e)able choice in lots of words. There's no right or wrong here ... only a preference – AnWulf Feb 1 '12 at 3:27
