File system- Which one to choose?

The file system is the way of storing, organizing and accessing data (files) in storage devices such as a Hard disk, USB devices, etc. Mac has its own set of file system and so does Windows. By default, Mac uses HFS+ also known as OS X Extended, this file system is native to Mac and is unsupported in Windows. Currently, windows use NTFS ( New Technology File System) which is partially supported by Mac ( mostly Read-only operations).

This issue can be resolved by choosing to format your storage device in either in FAT32 or exFAT file system as both of these filesystems are supported by both Mac and Windows. The FAT32 filesystem is relatively old and has some limitation on the maximum size of a file can be only 4GB or less and partition size cannot exceed more than 8GB. Whereas, exFAT is comparatively new, also is the most preferred file system. file system. In exFAT. there is no limitation on maximum file size( very high) and also for maximum partition size of the storage device. Therefore, we would request you to use modern filesystem exFAT as it supported in many platforms.

Other filesystems supported by Mac are:

  • OS X Extended (Case-sensitive, Journaled): Similar to Unix operating system, a Filesystem with case-sensitive name, eg: Document and document are two different files.
  • OS X Extended (Journaled, Encrypted): A file system in which content will be encrypted, you will have to enter the password to access files.
  • OS X Extended (Case-sensitive, Journaled, Encrypted): This filesystem is an amalgamation of above two cases i.e. both encryption and case sensitive.

These filesystems are exclusive to Mac and are not supported by Windows. Recommend partition scheme is GPT (GUID Partition Map) as it is supported by both Mac and Windows.
