I did a search and found this:
"There is a limit of 100 MB per file for initial submissions (AND updates) to the resource Manager. As a workaround, you can create a split archive using 7zip or WinRAR and upload them. Resources can now have multiple files. " (end off quote_
You can also upload your mods to an off-site file host (I sometimes use google drive) and link to them.
I recommend you zip your mods.
I hope this information helps you.
Google has not deleted any of my stuff. When I post my zipped files there I change the settings so that anyone with the link can download, and then limit where I post the links.
There are many other upload sites, such as mega.nz, anonfiles.com, gofile.io, mixdrop.co and nopy.to.
