That is an impressively large Brain. It should work if you directly import the .brain file. TheBrain 9 would just need to rebuild the database, and not extract the entire BrainZip. Let us know if it works for you.
Thanks Sean, unfortunately, the very process of rebuilding the database causes the windows\temp folder to use up 260GB of free space on the c:\ drive and stall the process due to lack of further storage space for the conversion. That was the point of my post. Let me ask the question from another angle: is it normal to have the conversion process take up hundreds of GB's of temporary space, even for a megabrain, if all it is doing is rebuilding the database?
Either it's a current design limitation in TB9 or there's an error, either way I am unable to import my brain and I am unwilling to invest the time and effort to set up a 2TB+ of free drive space on c:\ to find out. It would be helpful to understand nominal behaviour of the import process and the expected size of temporary files in c:\windows\temp\thebrain\... folders during the process. Metta, I'll share my experience once it's done of course. Has anyone else managed to convert a large brain and get around the temporary c:\ location limitation? Jim
