Its a friend's computer, she has this strange problem for file naming, it doesn't allow her to save up to 31 characters... shorter than 31, may be around 10-15 characters? (An error msg about long file name would pop-up). But her zipped-file is able to save in longer name (31 characters form).

MAC OS X 10.6

Will look into it more to gv u a clearer description of the what exactly is the error-msg.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

I don't understand your question. Please structure your problem. 1. What is the current situation (OSX allows only filelength of 31 characters?) 2. What do you want to achieve (filenames longer than 31 characters)? Which OS X are you using? –  FiveO Jan 21 '13 at 10:52
Please give us an example of a file name that will cause this error, and exactly what the error message says; do not just say "an error msg". –  Dour High Arch Jan 22 '13 at 2:55

I'm able to give files 255 character names from Finder using 10.8 and an HFS+ volume.

HFS+ (which was introduced in Mac OS 8) should allow 255 character names, but it's not clear if HFS was limited to 31 or 255 characters. http://en.wikipedia.org/wiki/Hierarchical_File_System says that the maximum length was 31 characters, but also that the limit was only imposed by Finder:

Files were referenced with unique file IDs rather than file names, and file names could be 255 characters long (although the Finder only supported a maximum of 31 characters).


In January 1998, Apple released Mac OS 8.1 with HFS Plus, which included support for 255 character file names; however, Finder continued to limit names to 31 characters until Mac OS X.

It's not clear if the limit was removed in 10.0 or a later version of OS X.

The startup drives of new Macs should be formatted as Mac OS Extended (Journaled) (journaled HFS+) by default. If your drive is formatted as Mac OS (HFS), you could try try reformatting it, but it requires deleting all files and restoring them from a backup.
