Error message

nenhum .csv nesta pasta — aponte para a pasta do export ou para o zip

What it means

read_source() scanned the given directory recursively for .csv files and found none, so it cannot build the GDPR export dataset. The error directs you to point at the export folder (or the original zip) that actually contains Reddit's CSV files.

Solutions

Point opts at the extracted GDPR export folder that directly contains files like comments.csv, posts.csv
Or pass the original .zip export instead of the folder
List the folder (find . -name '*.csv') to confirm CSVs exist where you think they are
Re-extract the export if the archive was only partially unpacked

Example fix

// before
run(GdprOpts { path: "~/Downloads".into(), .. })
// after
run(GdprOpts { path: "~/Downloads/reddit-export-2026".into(), .. })

Defensive patterns

Strategy: validation

Validate before calling

use std::path::Path;
fn dir_has_csv(dir: &Path) -> bool {
    walkdir::WalkDir::new(dir)
        .into_iter()
        .filter_map(|e| e.ok())
        .any(|e| e.path().extension().map_or(false, |x| x.eq_ignore_ascii_case("csv")))
}
// assert!(dir_has_csv(&export_dir), "no csv in export folder");

Prevention

Point the tool at the extracted export root, not an arbitrary folder
Confirm CSVs exist with find <dir> -name '*.csv' before running
Fully extract the zip before passing the folder
Do not confuse tool output directories with the export directory

When it happens

Trigger: run() called with a directory path that contains no *.csv files anywhere beneath it (out.is_empty() after walking).

Common situations: Pointing at the wrong folder (e.g. the tool's own output dir instead of the unzipped export); an export that was extracted incompletely; a folder containing only .zst/.json parts of the export; case-sensitive extension mismatches handled differently by is_csv.

Understand the failure class

Background: "File not found" and ENOENT errors: why libraries can't find a file that should exist — this error's family across 50 libraries.
