Encrypted USD Stick is not detected on Windows

I have sometimes used FAT or exFat (partition scheme Master Boot Record or maybe GUID although 128 GB USB flash drive only then seems to show only a tiny fraction of the available space in Window 10 for some reason).

And then encrypted the files and/or folders as .zip:

zip -re output.zip input_file.txt input_folder

zip -h show help

-r recurse into directories

-e encrypt

Warning, the standard zip encryption is very weak and is easily cracked.

Veracrypt is the only drive encryption option I know of which is multi-platform (it was forked from the original True-Crypt project when the original developers abandoned the project).

There are other options to encrypt just files/folders:

You cannot use APFS format with Windows. You'll need to use MS-DOS or ExFat.

You'll need to use MS-DOS or ExFat.

Which you cannot encrypt with Disk Utility. You would need a third-party, cross-platform encryption scheme.

I don’t know. Never needed one.
