ReasonsExample charactersAvoid

You cannot use colons (:) in the names of files and

folders because Mac OS 9 (Classic) uses this

character to separate directories in pathnames. In

addition, some applications may not allow you to

use slashes (/) in the names of items.

These characters are directory separators for

Mac OS 9, Mac OS X, and DOS (Windows)

respectively.

: (colon)

/ (forward-slash)

\ (backward-slash)

File separators

These characters may not be supported or may

be difficult to work with when exported to certain

file formats, such as EDL, OMF, or XML.

¢ ™Special characters not

included in your native

alphabet

These characters are often used in scripting and

programming languages.

. , [ ] { } ( ) ! ; " ' * ? < > |Punctuation marks,

parentheses, quotation

marks, brackets, and

operators

White space is handled differently in different

programming languages and operating systems,

so certain processing scripts and applications may

treat your files differently than expected. The most

conservative filenames avoid all use of whitespace

characters, and use the (underscore) _ character

instead.

White space characters

such as spaces, tabs,

new lines, and carriage

returns (the last two are

uncommon)

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

allow only 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 eight characters plus a three-character file extension (.EDL).

Using Filename Extensions

Mac OS X and other operating systems can use file extensions when determining which

application to open a file with, or what method of transfer to use for a network transfer.

If you intend to transfer your media or project files to non-Mac computer platforms, you

should use standard file extensions for your files. Some common file extensions include

.mov (QuickTime movie file), .xml (XML file), .zip (ZIP compressed archive file), .aif (AIFF

audio file), .wav (WAVE audio file), .psd (Photoshop graphics file), .jpg (JPEG graphics file),

and .png (TIFF graphics file).
