openvimwrite path problem

There are no error-related messages, so it is not known exactly, but the error may be due to the separator character.

You should use the path separator character in the form c:/ instead of c:\.

However, pathlib modules are provided from Python 3.4.

It is easy to find out the absolute path after reading it as a relative path.

from pathlib import Path

file_path = Path('sample.png')

file_path.absolute().as_uri()
Out[15]: 'file:///C:/Users/Administrator/aaaa/sample.png'

If you specify a path with an invalid character, it will correct itself.

from pathlib import Path

file_path = Path('d:\sample.png')

file_path.absolute().as_uri()
Out[17]: 'file:///d:/sample.png'

Also, string interpolation in Python is very convenient. If you use f'' and put a variable or formula between {} as shown below, it will be substituted as it is. You don't need to paste strings one by one by one.

for i in range(10):
    print(f'c:/{i * 2}.jpg')

c:/0.jpg
c:/2.jpg
c:/4.jpg
c:/6.jpg
c:/8.jpg
c:/10.jpg
c:/12.jpg
c:/14.jpg
c:/16.jpg
c:/18.jpg
