Would anyone know if there is a limit on how deep a folder tree can go? If so what is the limit?Also what symptoms do we see when we hit that limit? Thanks

    The entire path length, including the drive letter and invisible <NUL> at the end cannot exceed 260 characters.  See the Maximum Path Length heading in this article.

    If the limit is exceeded, Windows Explorer will usually give an unhelpful "The system cannot find the file specified" error.  The command prompt will return "The full path of <path> is too long".

    I have a share folder and people are creating folders within folders pretty deep. Some of the deeper ones are having problems accessing it.

    Folder tree limit is 256 caracters, problem you get when going over this limit is that you get errors when saving a file in that tree.

    Other symptoms you may experience are, cannot remove folder"the filename  or extension is too long", Cannot copy The file name you specified is not valid or too long. Specify a different file name, or unable to create the folder "", The specified path is invalid.

    You can resolve the problem usually by rename one or two file or folder names. Pick the long one to start.
