There is no file size limit at 14.1GB.

That 16GB of capacity includes everything - including losses to
formatting and file system chunking. Also, stick sizes are often in
billions of bytes, not actual gigabytes - there's a significant
difference when you get up into high numbers.

Sometimes cheap USB sticks are also deliberately mislabeled and
sometimes even fraudulently programmed to report higher capacities than
they have.

But I don't think any of that is your problem:

My understanding is that FAT32 has a maximum file size of 4GB. This
website seems to confirm that:

I don't know how you got to 99%.

To store files larger than 4GB, you will need to use NTFS or one of the
Unix filesystem types such as ext4. This wikipedia page has a good
comparison of filesystem limits:

https://en.wikipedia.org/wiki/Comparison_of_file_systems

NTFS is pretty much the only choice if you need to share between Win
and random nonWin systems, but it is a very sensitive filesystem;
always properly eject it before removal.

ext4 is much more robust, and with third-party software you can still
read it on Windows:

However, I'm not sure it can read encrypted partitions.
