Restricting Length of Filenames
Although current file systems such as HFS+ (used by Mac OS X) allow you to create
filenames with a 255-character limit, you may want to limit your filename length if you
intend to transfer your files to other operating systems. Earlier versions of the Mac OS
only allow 31-character filenames, and if you want to include a file extension (such as .fcp,
.mov, or .aif ), you need to shorten your Mac OS 9-compatible filenames to 27 characters.
For EDL files, which may be stored on DOS-compatible disks, you should limit your
filenames to 8-characters plus a 3-character file extension (.EDL).
