Is Tie :: File lazily loading a file?

Question

I plan to write a simple text viewer that I believe will be able to process large files. I was thinking about using Tie::Filefor this and how to break lines. Is this loading lines lazily or all at once?

Answer 1

It will not download the whole file. From the documentation :

The file does not load into memory, so this will work even for gigantic files.

Answer 2

memory.
