How a script organizes several files

Choose the files: The script finds the .md files and reads their text.

Apply one rule: For example, it can use the first line of each note as a title.

Write the result: It creates summary.csv on the machine or server that ran it.

Quick checkChoose the best answer

A Python script will summarize 200 Markdown files into CSV without overwriting sources. What preparation matters most before running?

Confirm input directory, output file, and overwrite rules, then test with a small copied sampleRun it directly on all 200 production files and use editor Undo if the result is wrongCheck only that the script starts, without verifying output columns, encoding, or malformed files

List the exact paths the Python script will read and write and overwrite no Markdown by default. Trial it on three copied files, show the resulting CSV and error report, and wait for confirmation before processing the full directory.
