I try to display a very large downloaded OSM file 14'000'000'000

[jjenny@…]

What steps will reproduce the problem?

1. Open africa-latest.osm
2. Data analysis
3. Error

What is the expected result?

What happens instead?

Please provide any additional information below. Attach a screenshot if
possible.

Far smaller files will make JOSM extremely laggy (just one city is enough), I am not sure is it reasonable to expect that editing continent sized dataset will work.

With only 512 mb memory available, JOSM will not work with much data. See Install Notes for instructions.

On the other hand I doubt that working which such a huge area is useful. Maybe you should only open parts of ther area or/and data.

JOSM is not designed to edit an entire continent at once, please use smaller extracts.

Reopen if you have a specific error on a human-sized dataset (with a little more detail than "Error" please).
