Rambling reply but I wish to add my two cents to this.
Thinking through this from a display standpoint. Imagine how a 3 layer 1000 character folder limit would show on a user's screen. 180 characters reaches nearly to the middle of my 24" monitor and I'm on a small font setting.
What is the display impact as the folder tree (inlcuding workspace details) would need to wrap? In theory, a workspace could end up with multiple lines of text cluttering up the top of the screen.
Out of curiosity, why would anyone want 1000 character file name? Take an example of 3 documents added to an Outlook outbound message. How would 3 1000 character file names be displayed in the attachment area? How would that look to the recipient?
Now the user would like to use the NDoffice plug in to change the attachment's name/convert to PDF etc via the native ND Edit button. That tool's window currently cannot be expanded. If the files have similar names for the first 50 or so characters, the user will have issues distinguishing which is which.
Can I second the request to add a setting at the cabinet/repository level so firms can decide to limit this option? Then, enable the ability to expand on a case by case basis down to the workspace/folder level?
