6.24 Changing a file system
This operation lets you change the volume file systems of the following type:

FAT16 to FAT32 and back

Ext2 to Ext3 and back
The table below describes main differences between the file systems.
Feature FAT16 FAT32 Ext2 Ext3
Maximum volume
size 2 GB (4-KB
Cluster Size) or
4 GB (64-KB
Cluster Size) 2 TB (4-KB
Cluster Size) or
8 TB (64-KB
Cluster Size) 2 TB (4-KB Block
Size) or 32 TB
(8-KB Block
Size) 2 TB (1-KB Block
Size) or 32 TB
(8-KB Block
Size)
Maximum file size 2 GB 4 GB 2 TB 2 TB
Maximum file
name length 255 255 255 254
Partitioning
scheme MBR MBR MBR, GPT, APM MBR, GPT
To change a file system
1. Right-click the volume whose file system you need to convert, and then click Change file system.
2. Select the required file system.
3. Click OK to add the pending file system changing operation.
The results of the pending operation are immediately displayed as if the operation had been
performed.
To perform the pending operation you will have to commit it (p. 23). Exiting the program without
committing the pending operations will effectively cancel them.
6.25 Specifying i-node density
This operation applies to volumes whose file systems are Ext2 or Ext3.
The i-node is the main data structure for Linux Ext2/Ext3. All of a files information, with the
exception of its actual name and data, is stored in the i-node. Each file has its own i-node. Each i-
node contains a file description, including number, file type, size, data block pointers, etc. Space for i-
nodes is allocated when you install the operating system or when a new file system is created. The
maximum number of i-nodes, and hence the maximum number of files, is set at file system creation.
Running out of i-nodes prohibits the creation of additional files and directories on the volume even if
there is sufficient disk space. I-nodes themselves consume disk space, so specifying the i-node
density lets you organize disk space in the optimal way. I-node density is determined by specifying
the number of bytes per i-node. Usually, the default value is 4096 bytes per i-node.
Important: If you change the i-node density of a boot volume the operating system will become unbootable. To
restore the system bootability use a boot loader.
To specify i-node density
1. Right-click the Ext2/Ext3 volume, and then click Change i-node density.
2. In Bytes per i-node, specify the required value.
