exFATlevyjä

ExFATlevyjä, also known as exFAT, is a file system developed by Microsoft. It is designed to provide a common file system for flash drives, memory cards, and other removable storage devices. ExFAT was introduced to address the limitations of the FAT32 file system, which has a maximum file size limit of 4 GB and a maximum volume size limit of 2 TB. ExFAT supports file sizes up to 16 exabytes and volume sizes up to 128 petabytes, making it suitable for large storage devices.

ExFAT is a cluster-based file system, similar to FAT32. It uses a master file table (MFT) to store file and directory information. The MFT is a database that contains records for each file and directory on the volume. Each record in the MFT contains information such as the file name, size, and location on the volume.

ExFAT is designed to be simple and efficient, with a focus on performance and reliability. It does not support advanced features such as file permissions, encryption, or journaling, which are found in more complex file systems like NTFS. Instead, exFAT is optimized for speed and simplicity, making it ideal for use in embedded systems and other applications where performance is critical.

ExFAT is supported by a wide range of operating systems, including Windows, macOS, Linux, and Android. It is also supported by many third-party applications and utilities, making it a versatile choice for a variety of storage devices. However, it is important to note that exFAT is not a secure file system and should not be used for storing sensitive data, as it does not support encryption or other security features.
