script to download the attachments from an email having a specific subject

The following code downloads the attachments from the outlook email having a particular subject line (ADP Files). When i execute the script it generates an error saying FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\qwerty\desktop\EMAIL ADP\attachments\1494075600130_1640807852.xls'.
What could be the problem?

import imaplib
import email
import os

svdir = 'C:\Users\rnandipati\desktop\EMAIL ADP'

mail = imaplib.IMAP4_SSL('outlook.office365.com',993)
mail.login("[email protected]", "R7!")
mail.select("Inbox")

typ, msgs = mail.search(None, '(SUBJECT "ADP Files")')
msgs = msgs[0].split()

for emailid in msgs:
    resp, data = mail.fetch(emailid, "(RFC822)")

    email_body = data[0][1]
    m = email.message_from_bytes(email_body)

    if m.get_content_maintype() != 'multipart':
        continue

    for part in m.walk():
        if part.get_content_maintype() == 'multipart':
            continue
        if part.get('Content-Disposition') is None:
            continue

        filename = part.get_filename()
        if filename is not None:
            sv_path = os.path.join(svdir, filename)
            if not os.path.isfile(sv_path):
                print(sv_path)
                fp = open(sv_path, 'wb')
                fp.write(part.get_payload(decode=True))
                fp.close()
