Your directory structure is too long.
EG C:\1234\542\frgty\5434565\6453565\87564\j5y54grg\75676575.
The Folder you are creating would appear to be too deep inside other folders and thus the path to acess this folder is too long.
Open my explorer and then locate the directory the folder is in now right click on the folder and rename the folder and shorten the path of folder.long file names are supported up to 255 characters.
