Importing large Thunderbird Folder

Is there a physical limit to opening a thunderbird folder into a new account, either by design, or by fault?

I want to open an old inbox (420MB) into a new account.  I have tried just swapping the file over and re-starting TB but it just thinks for a few minutes whilst it decides which 'emails to index' then stops and nothing appears.

I can create sub-folders and add items to that.

If I try to copy and paste an email into the inbox it says the file is in use.

have you deleted the msf index file for the inbox before swapping the mail file?

This should confuse thunderbird if not.

Yes.

Also renamed it.

In both cases it re-created the *.msf and then took ages to think about doing nothing...
latest thunderbird?
plan b could be to test this with postbox.
See http://www.postbox-inc.com/

Create a new account, stop postbox, then go to to the profile folder and replace the inbox (delete the msf file if already created).

You find the profile under C:\Documents and Settings\[User Name]\Application  Data\Postbox\Profiles\

That software comes with a 30 days trial, no need to register. It is 100% thunderbird compatible. If it's able to repair the mailfile try to move it back to thunderbird.

Thanks for the suggestion - that had the identical result.

It is the latest version of TB but I may have upgraded the latest verison then tried to attach the TB folder without running TB in the old Windows Profile that belonged to the TB - if that makes sense?
ok plan c:

the mbox format is just plain old text!

How about that:
in thunderbird you create 4 folders name e.g. folder1...4
then stop thunderbird.
Now you split your big inbox into 4 100mb chunks. wordpad should do it (make a backup before!!!!)
A split is well placed before a code like below (this is really plain text)
Name each split as folder1, folder2, folder3 according to the names you gave above.
Leave a zero size inbox (and delete the inbox.msf file)
Then start thunderbird and check if you got all mails.
Now arrange all emails back into the inbox - or into an folder for each year (I do that)

In thunderbird you can use the search option to seach for big emails in case you want to get rid of some.

Unable to open the file both PFE and Wordpad hang.

Wordpad gets to 850mb of memory before hanging.

There is plenty free memory at this point.

420MB too much - it tries to open it and does display something whilst going quiet - but the moment you try to scroll it churns for 4-5 minutes then goes quiet again - and repeat.

Not a complete hang, but as good as.

At that point there is well over 2GB free memory.

See attached for what does display.

Line 1 is 430674520 bytes long
Split into 33554429 byte lines?

What that showed was that the files was 420mb of spaces/special characters!

So a corrupt file :(

Luckily I have secondary backups (which really I should have looked at right away!) and that opens up, all 420MB, in a matter of seconds and looks fine!

Now opens fine - thanks for all your help :)
Great, I still advertise to split the email folder in years, in thunderbird...

It is the Wife's old inbox - i have just deleted loads of photos (which are already saved onto her HDD) and emails from 4-5 years ago....

Then compacted...

420mb is 32MB!

She has beed educated :)

Thanks again.
ok this sounds good.
32 MB is really no issue.
 
Just in case, I use this for backups.
