how to remove file/folder path from string using regex

I want to remove any file/folder path from the given string. I use regex to identify the paths and replace it with empty string.

This is my example string.

\\172.44.43.90\c\Logs\AccessService\2021\June  The public disk is: \\diskA\FolderB\SubFolderC\Files file path /log/file.txt some lines /log/var/file2.txt 

My require output is,

\\172.44.43.90\c\Logs\AccessService\2021\June
 \\diskA\FolderB\SubFolderC\Files
 /log/file.txt
 /log/var/file2.txt

I should remove the above strings and should get my final output, The public disk is: file path some lines

I tried below regex. but it is only identifying files. I need to identify any dynamic files/folders. Note: forward or backward slash may come in the start of the filepath.

My code :

 import re
 re.sub(r"(\/.*?\.[\w:]+)", "", input)
