MiniTool Partition Wizard
Change Cluster Size
Smaller clusters might significantly reduce disk space losses related to
the fact that any file occupies at least one cluster/block. However,
reducing FAT32 partition cluster size might increase the space occupied by
the file allocation table (FAT) and slow down file access.
Launch this function, you need to select a partition in
MiniTool Partition Wizard - Disk/Partition List Window first, and then click the
menu: Partition -> Modify -> Change Cluster Size.
NOTE: If you like to change small cluster size to large, you need keep more free space for the partition.
