2. Try to rename it into exactly 256-character length name.
3. TC displays the warning dialog:
Problems:The target name length (264) is more than 259 characters!
Additionally, the last part of the name is 257 characters long, which is longer than the maximum possible 256 characters!
* First, it claims the file name length is 257 characters instead of actual 256.
* Second, it says the maximum possible length is 256 characters, but does not allow to create such a file.
According to NTFS specifications, the maximum possible length is actually 255 characters, so that explains why 256-chars file name cannot be created, but the translation line 1699 should then look like "…longer than the maximum possible 255 characters!".
P.S. Maybe TC takes into account the trailing zero byte, but from the users' point of view it's not obvious.
