What are the causes of long path errors?

There is a specified limit of characters in the case of naming a file. Generally, this limit is fixed at 255 characters for the entire name of the file. Sometimes, when a file is stored in a root drive with 255 characters then it is okay. However, the entire file path cannot be more than 259 characters. Now you might get confused about the file name and file path. File name is just the name of the file along with the extension of the file. For example, there can be a text file say, Long path then the filename would be longpath.txt which has got 12 characters. On the other hand, path refers to the file name along with the address of the file. For example, if a file is created in a folder name LPT in D drive, then the long path would be D:\LPT\longpath.txt which has got 19 characters. So if any file exceeds the limit of 259 characters for the path or 255 characters for the filename, then the problem of long path arises.
