hi all

im new linux user and i need help with creating partitions

i have 750GB space on laptop and need something like this

1. partition where is ubuntu installation (so if i need reinstall i just format that partition) lets say 50GB of space (is that enough)

2. swap area (i read 4 GB that i need)

3. here i want like 200 GB for my work projects

4. rest of the space for fun like movies or something


and question is what mount point i need to use and what type for them (ext4 and swap if i read correctly)
and how do i keep moving (read and write on them) without using gksudo nautilus

any way to just moving between them like on windows (double click)
