I'm not sure if that torrent really graduated past experimental yet. 😛 In any case, note that I wrote down a few suggestions on what to do here. For finding all of your own posts, taking the sample Python script as a guide:
#!/usr/bin/env python3
import os
backup_directory = 'backup-data'
check = ['username\n']
for root, dirs, files in os.walk(backup_directory):
for file in files:
if file.endswith(".txt"):
file_path = os.path.join(root, file)
with open(file_path, 'r') as f:
content = f.readlines()
if content[3] in check:
print(file_path)
Note that even on an SSD that'll take a while.
