Increase file name character limit
People who have multiple folder layers and detailed file names are severely penalised by having the 260 / 400 character limit to a file name.
This is a poor limitation and is leading me to consider leaving the OneDrive service. I'm certain you can come up with a solution to increase this limit, remove it, or make it so that the file path isn't stored in the file name!
Increase the character limit to 500. It is frustrating and annoying to not be able to name saved files by their description and content due to an unnecessary limitation. This has forced me to waste time saving to my desktop (which has no such character limit) and then manually move the file back into the sub-folder on OneDrive, usually for or 5 layers deep. Again, this is very annoying, and at present there is no work around!

If only we could use the shortname of folders to mitigate this problem.
They should fix this, if you think; the beggining (C:/user/user/Business/ecc...), and arriving to the sixth level of folders (totally reasonable), let say 25 characters each level (totally reasonable), we already have ~210, leaving just 50 character in case of SharePoint Server, for the file name assuming that no other level of folder will be add (very unlikely). I don't know why it doesn't allow it, if the code of SharePoint, I don't know, but please fix it..
