The .zip file specification states:
4.4.17.1 The name of the file, with optional relative path.
The path stored MUST not contain a drive or
device letter, or a leading slash. All slashes
MUST be forward slashes “https://stackoverflow.com/” as opposed to
backwards slashes ‘\’ for compatibility with Amiga
and UNIX file systems etc. If input came from standard
input, there is no file name field.
