→Loading the file: interrelated warning
Therefore, you should only handle large files by using the GRAMPS GRDB format. You do this by creating a new GRDB file and importing the large file into it. This can take a long time, so do it in the evenings! If you '''enable database transactions''' in the Edit->Preferences->General menu tab, the importing of data will then be much faster.
Also if you have a file that large it might be prudent to break up file into smaller pieces (i.e. Maternal & Paternal lines in different files) so you only have to use a smaller file.

As there are many people, loading the person view might take some time. See a comparison of [[GRAMPS Performance|performance]] on large datasets, between different GRAMPS versions.
