# Aider chat conversation:
USER: I just tried aider on a project where the folder names have spaces, and it has an issue parsing the diffs.
For example:
```diff
--- PRAW and URS Reddit Scraping/Classify.py
+++ PRAW and URS Reddit Scraping/Classify.py
@@ ... @@
def classify(filename:str, model: str = 'gpt-3.5-turbo-1106'):
d = json.load(open(filename))
for post in d['fetched_posts']:
messages = copy(MESSAGE_TEMPLATE_CLASSIFY)
...
```
Gives:
```Allow creation of new file PRAW? y```
Which is not correct, a new file is not being created here.
ASSISTANT: To address the issue with folder names containing spaces, we need to update the `find_diffs` function in `udiff_coder.py` to correctly parse file paths that include spaces. The current implementation seems to split the file path on spaces, which leads to incorrect behavior when folder or file names contain spaces.
Here's the diff with the necessary changes:
```diff
--- aider/coders/udiff_coder.py
+++ aider/coders/udiff_coder.py

def find_diffs(content):
# We can always use triple-quotes, because all the udiff content
# is prefixed with +/-/space.
if not content.endswith("\n"):
content = content + "\n"
lines = content.splitlines(keepends=True)
line_num = 0
edits = []
while line_num < len(lines):

line = lines[line_num]
if line.startswith("```diff"):
line_num, these_edits = process_fenced_block(lines, line_num + 1)

block = block[2:]

```
This change ensures that the file path is correctly extracted from the diff headers, even if it contains spaces. It also adds an assertion to check that the file paths for the original and new files match, which is a common requirement in diffs.
This fixes issues with /run on Windows which usually manifested as encoding errors.
Sample: Error running command: 'charmap' codec can't decode byte 0x9d in position 298: character maps to <undefined>
