storeFile from subFolders Unable to open file

[PeroPonneso]

Hi, thanks for pysmb, it is a nice tool.

I'm running the code from a folder in Windows Server 2019 (also from Windows 10) to a share on Linux 20.04.

When i transfer a file in the same folder as the code to the share the operation is completed successfully

path = ""

print('direzione:  da', myname, 'a', ip)

conn = SMBConnection(user, pw, myname, srv, use_ntlm_v2 = True)
assert conn.connect(ip, port=139)

print('connessione:', ' instaurata')

#file from local to share(Windows LOC -> RM Linux)
filenames = glob.glob("*.png")
elts = len(filenames)
print('file trovati: ', elts)

print('writing: ', 'started')
for i,f in enumerate(filenames):
    sys.stdout.write('\r')
    with open(f,"rb") as file2transfer:
        conn.storeFile(share,path + f, file2transfer, timeout=30 )
        file2transfer.close()

print('writing: ', 'completed')

conn.close()

Now i need to send a bunch of files from different folders to the same share. To achieve that i tried modifying the writing part like this :

path = "branch1\\"

#file from local to share(Windows LOC -> RM Linux)
f= "file1.png"

print('writing: ', 'started')
  with open(path+f,"rb") as file2transfer:
      conn.storeFile(share, path + f, file2transfer, timeout=30 )
      file2transfer.close()

print('writing: ', 'completed')

the open() function gives back the right name and doesn't throw exception; the conn.storeFile() throws:

OperationFailure: Failed to store branch1\file1.png on LinuxShare: Unable to open file

I've tried different combinations of path and filename using "\" , "/", "./" and ".\" but it doesn't solve the problem. Am i missing something or misunderstanding how i should format the function for files in different locations?

Thanks

Is branch1 created and writable by the user on the remote server?

[PeroPonneso]

Thanks for the attention @miketeo,

If branch1 is already present in the remote and the local (with correct authorizations) with the same relative path configuration it works. I wanted to grab files from, lets say:

from Windows:
root\branch1\file1
root\branch2\file2
root\branch3\file3
...

to Linux:
root\files\file1
root\files\file2
root\files\file3
...

having a different folder configuration between the two. I'm quite sure i'm just using the store function badly.

Thanks again for the reply
