[Dav7]

Citar:1. Copy the files to another partition;
2. Launch the programmer;
3. Select the partition with no data, click Partitions>Delete, then you will get an unallocated space;
4. Use "Resize/Move" function for that partition to obtain this unallocated space. Select the partition to be resized, click Partitions > Resize / Move, the minimum and maximum sizes that you can resize a partition appear below the map; Or position the mouse pointer on the left or right handle, the mouse pointer changes to a double-headed arrow, drag the handle to the size you want;
5 Reboot your computer and then you will "merge" these two partitions with EASEUS Partition Manager.

quando chego ao ponto 4. não consigo seleccionar Resize/Move, não dá para seleccionar essa opção!!

e o espaço fica ali Unallocate
