How to increase Flash Drive Capacity

How to increase Flash drive space? There are many types of file systems, like FAT, FAT 32, and NTFS. But NTFS file system has the advantage of compression option.

Thumb drives or flash drives when you buy one, are ready to use. Formatted and ready for your use. And usually formatted in the FAT32 file system.

The Flash drives available in the market are almost always formatted in the FAT32 system (File allocation table). The FAT 32 system has a much larger cluster size.

The NTFS (New technology file system) is more stable and has a smaller cluster size, thereby indirectly increases the storage capacity.

Besides the disadvantage with the FAT32 system is that it can handle file size up to 4GB only. This means if you try to copy files larger than 4GB you will not be able to do so even if you have space in the flash drive.

When you try to transfer files larger then 4GB, Windows will show the message  “There is not enough space“. This is because of the limitations of the FAT32 system.
You can try yourself.

So, if you need to copy files larger than 4GB, make certain that the file system on the Flash drive is NTFS and not FAT32.
