OneDrive NGSC for Mac crashes with invalid/long file names

Even if you had such a tool (you could write a script that checks file names and path lengths) you would have to use it for EVERY new file that is stored on OD4B. Better solution: * educate your users about the limitiations and best practices. You CAN use most of the special characters in OS X but you are not advised to do so if you intend to use the files in other systems. ** https://support.microsoft.com/en-us/kb/3125202 ** https://support.apple.com/en-us/HT202808 * provide meaningful error messages in OD4B instead of crashing (this means you, Microsoft!)
