Hey!
It sounds like you just need to initialize a `CorpusReader` object from a custom set of text files in your local drive.
```
from nltk.corpurs.reader import PlaintextCorpusReader
root = '/usr/local/corpora/folder_with_corpus_files/'
reader = PlaintextCorpusReader(root, '.*\.txt')
```
You should then be able to call the `Reader`'s methods you need:
`reader.words()`
`reader.sents()`
