If a file name contains more than 11 Japanese characters, Mac OS X 10.4 may not be able to copy the file to an affected AFP server—a server that is running on an operating system other than Mac OS X or Mac OS X Server.
Note: Apple Filing Protocol (AFP) is the type of service known by names such as Apple File Service (Mac OS X Server), Personal File Sharing (Mac OS X and Mac OS 9), AppleShare IP, and Microsoft Windows Service for Macintosh.
When you try to copy an affected file to an affected server, you could get the following message:
"You cannot copy some of these items to the destination because their names are too long or contain invalid characters for the destination."
This issue may also cause unexpected loss of the file at the affected server. For example, if you copy a file from the server to your Mac OS X 10.4 client, modify the file, and then try to copy the file back to the AFP Server, you may get this message:
"An item named 'File name' already exists in this location. Do you want to replace it with the one you are moving?"
If you click the Replace button, you will get this message:
"You cannot copy the item because the name is too long or includes characters that the disk cannot display."
The result is that you lose the old file on the AFP Server and cannot copy the edited file to the AFP Server until after you rename it.
This issue is addressed in Mac OS X 10.4.3 Update. To avoid this problem, update to Mac OS X 10.4.3 or later.
