Why do some CDs have le reading?

The maximum possible size for a file on a FAT32 volume is 4 GiB minus 2 B (232−2 bytes). For most users, this has become the most nagging limit of FAT32 as of 2005, since video capture and editing applications and some other software can easily exceed this limit. Most new windows machines now ship with NTFS and thus avoid these problems, but those who run dual boot systems or who move external data drives between computers with different operating systems have little choice but to stick with FAT32 (although between Windows and Linux it is possible to use ext2 through the use of external drivers such as ext2 IFS).
