Assigning File Systems to Partitions

Now that you have your partitions set up, it’s time to assign them file systems. A file system determines how data is organized and stored on the partition. The most common file systems are:

FAT32: An older file system that is compatible with most operating systems. It is limited to a maximum partition size of 32GB and file sizes of 4GB.
NTFS: A more modern file system that supports larger partitions and file sizes. It is the default file system for Windows operating systems.
exFAT: A newer file system that is optimized for flash drives and other removable media. It supports larger partitions and file sizes than FAT32 and is compatible with both Windows and Mac operating systems.

The table below summarizes the key differences between these file systems:

Feature	FAT32	NTFS	exFAT
Maximum partition size	32GB	2TB	16TB
Maximum file size	4GB	16TB	16TB
Compatibility	Most operating systems	Windows operating systems	Windows and Mac operating systems

Once you have chosen a file system, you can use the partitioning tool to assign it to the partition. To do this, select the partition and then click on the “File System” drop-down menu. Select the desired file system and then click on the “Apply” button.

Setting Partition Sizes and Types

Once you have chosen the desired partitioning scheme, you need to specify the size and type of each partition. This is a critical step, as it will determine how the data is stored on the USB drive and how it can be accessed.

Partition Size

The partition size refers to the amount of storage space allocated to each partition. You need to carefully consider the size of each partition based on the intended use of the USB drive. For example, if you plan to store large media files, you will need a larger partition size for those files.

Partition Type

The partition type defines the file system that will be used on the partition. There are several file systems available, each with its advantages and disadvantages. Some common file systems include:

File System	Advantages	Disadvantages
FAT32	Widely compatible, supports large files	Has a file size limit of 4GB
