    File Random
In summary, the most efficient way to randomly choose a word from a file containing a list of words involves reading the file to determine the total number of words, generating a random index within that range, and then retrieving the word at that index. This method minimizes memory usage while ensuring a uniform distribution of random selection. For large files, using a streaming approach can further optimize performance by avoiding the need to load the entire file into memory.

Yes, files like the ones the OP linked to could be pre-processed to add an index section at the front.
