Revised section about 4GB and maildir, but not 100% sure I've got it right. Needs more thought Wsm 21:20, 21 May 2014 (UTC)

Max folder size

Supporting Mozilla Suite & Thunderbird for several years on several versions of Windows, the max size has always been 2 GB. Right this moment I have a user with TB2 on WinXP Pro SP2, and he has hit the 2GB limit. Where does the article get the 4GB number? Guanxi 19:30, 18 June 2007 (UTC)

Its based on several bug reports where one of the Thunderbird developers stated that the maximum folder size is 4GB unless the file system limits the file size. A couple of users have mentioned in the forums that they're using a 3GB inbox with no problems, and I vaguely remember somebody (was it ausdilecce or wintogreen?) writing a program to verify that Thunderbird could support a 4GB folder. If you create a thread in the Thunderbird Support forum with more details about your problem I'll try to help. Tanstaafl 22:04, 18 June 2007 (UTC)

In the bug cited, and in 378142, the developer said it should be 4GB, but all the reports were of 2GB limits. Again, that matches what I have seen consistently on many versions of Moz Suite/Thunderbird on many versions of Windows over years. I've never seen a folder larger than 2GB. Are you sure someone has confirmed a larger one? Guanxi 22:41, 21 November 2007 (UTC)

Yes, I'm sure. I've seen several cases where users exceeded 2GB and mentioned that above. I also mentioned a recent case of a folder that was approx. 4GB from http://forums.mozillazine.org/viewtopic.php?p=3143933#3143933 in the article.
There is always the possibility that somebody might run into a 2GB limit due to a configuration specific bug that wasn't fixed in David Bienvenu's 2004-04-13 bug fixes or some new bug. However, none of those bug reports seem to be confirmed. Some cases might be due to the folder being corrupted (a common problem) and the person jumped to the wrong conclusion. Given how almost anything can break for somebody sometime, it seems more appropriate to document the limits most people will see. I removed your change and added a generic caveat at the beginning of the article. Tanstaafl 00:45, 22 November 2007 (UTC)
The 2GB bug is confirmed, very many times, in the bugs you and I both mentioned. You have one mention of 4GB and many of 2GB. It makes no sense not to at least warn users about 2GB. Guanxi 00:58, 22 November 2007 (UTC)
You seem to have problems counting, "a couple" plus one plus one does not equal one. The "though many users report a 2GB limit" text you added was misleading. There is a big difference between the possibility that a small number of users may still run into a 2GB limit (because they ran into a use case that the developer overlooked or hasn't been able to reproduce yet) and what you said. Who cares how many times somebody ran into a problem before the developer fixed it? We're talking about now, not the past.
Just because one person adds a comment two years later to a RESOLVED FIXED bug report that they can't go past 2GB doesn't necessarily mean that bug isn't fixed for most users, especially if the symptoms are different. The Mozilla developers state multiple times the problem is fixed, 207400 is fixed, 343907 is new, OSX specific, and has different symptoms, 378142 is unconfirmed, and I've added prominent text to set a users expectations that they could run into a bug for any of the limits at any time. Why isn't that sufficient to leave things as they are? Tanstaafl 09:27, 22 November 2007 (UTC)

Article needs update to account for changes in 3.1, introduced by bug Bug 532323 - 4 GB limit of IMAP offline-store breaks sync of gmail "All Mail" and other systems(4GB limit is on Win, 2GB limit if Linux/Mac). 3.1 supports 64bit offsets, so essentially the new limit is whatever the file system supports Wsm 18:29, 24 June 2010 (UTC)
