I have two folders in the same directory as the python file, `mr robot`, and `subs`. I have four files with four different names in both files. I stored the names of the files in `mr robot` without an extension in a list (`file_s`). I want to rename the files in `subs` directory with the names in the list. But when I run it, it throws this error:

```
FileNotFoundError: [WinError 2] The system cannot find the file specified

```

Here is my code:

```
import os

currdir = os.getcwd()
vidfiles = os.listdir(f'{currdir}/mr robot')
subfiles = os.listdir(f'{currdir}/subs')
file_s = []

for file in vidfiles:
    filename, _ = os.path.splitext(file)
    file_s.append(filename)

for filename in file_s:

    for sub in subfiles:

        os.rename(sub, f'{filename}.srt')

```
