This is great timing. The Cantonese Wikipedia has recently been going
through a drive to clean up old files, some dating back to 2006, which
haven't been moved to Commons because... CommonsHelper is frankly a bit

The FileExporter will soon be released as a beta feature to all wikis. The
planned deployment date is January 16.
Some background: Files from local wikis should be transferred to Wikimedia
Commons if their license allows it. This way, they can be used by all
wikis. But if you wanted to import a local file to Commons in the past, you
couldn’t properly transfer its file and page history. It was a wish from a
survey of the German-speaking communities to find a solution to this
Now, the FileExporter makes it possible to import a file from a local wiki
to Wikimedia Commons, while keeping its history intact. A first version has
already been a beta feature on a few first wikis since June 2018.  Since
then, bugs were fixed and features were added.
If you’re interested in importing local files, please give the feature a
try. Even though it’s a beta feature, you can use it for real file imports. Please
note that in order to get started, you need to
activate the beta feature “FileExporter” on your wiki , and
make sure your wiki has a proper configuration file. Configuration
files are maintained by each wiki's community. They define, among
other things, whether a file can be exported. Exports from wikis without a
configuration file are blocked. Find more more information in the
We’re looking forward to your feedback on the central feedback page!  A
