[SOLUTION]: Uploading world biger than 50M

.. is anyway impossible. BUT YOU CAN....

1) download your world
2) download "minutor" mapper
3) open your world in minutor and find unused regions (region =512x512fields or 32x32chunks, r.0.0.mca is from 0 to 512x and 0 to 512z)
4) open your world/region directory
5) delete unused r."x"."z".mca files
6) zip your world and look at the .zip properties.

My world is now 25,5M instead of !180.7M!
Without loosing any structure or building.

After upload your world will be re-generated when you visit unused region, it wil be generated new r."x"."z".mca

PS: as a bonus of attenuating your world, it will start faster.

Greating Jeez

Can you upload your world to uloz.to and send me link?
I will look on it.

It is true you cannot upload the very same map.
But chunks/regions where you did not build any structures and delete them, will be restored/regenerated by rules according to seed.
Temples on the very same place, biome types on very same place, villages and witch huts on very same place, ( can verify ba AMIDST.jar)
In this case does not matter if that tree was here or over there.

And 50M is enough for a very nice piece of created and builded world.
In other case it is no other way then rent a piece of server on payd areas.

Anyway, please upload your world and let me see.

Jeez

You are jealous.
Ok, Ok, means nothing for me.
I just tryed to help you.
