Currently it is not possible to use the listPath() Method from the SMBConnection Package. I think this is a important feature of the PYSMB Library as it is used to check if a file already exists on the Destination Server. Please expose it in your Code to vastly improve usability

store_file() leads to "TypeError: can't concat bytes to str" exception in smb\smb2_structs.py.
It looks that opening file_obj in binary mode ('rb') fixes the issue.

When I try to store a binary file to smb server, such as image.bin, the destination file is a damaged one when smb.store_file completed.

The issue was fixed after I changed the code as below:

def store_file(self, file_obj, dest_path=None, share_name=None, retries=3):
    if not dest_path:
        dest_path = self.file_path
    assert dest_path, 'Destination path is unset'
    share_name, dest_path = self.__guess_share_name(dest_path, share_name)
    if type(file_obj) is str or type(file_obj) is str:

-- file_obj = open(file_obj)
++ file_obj = open(file_obj,'rb')
