Upload ZIP during project creation
You can upload source files as *.zip during project creation.
When you upload a *.zip archive the content is extracted automatically and you can individually specify if each file is to be treated as a Translatable or Reference file. The original *.zip archive is kept as a Reference file, so you always have the original.
The directory structure of the archive is also preserved, which helps you handle situations where you have multiple files with the same name in different folders or archives.
