I am trying to uninstall a custom module that we created. When I uninstall the module, it is deleting tables that are in the module along with some other tables in database not connected to this custom module. I thought deleting Uninstall.SqlDataProvider from the module folder will stop from running the Uninstall.SqlDataProvider script when I uninstall the module, but it is still deleting the tables along with unconnected tables. Looks like Uninstall.SqlDataProvider script is either saved somewhere in the database or files. Where does DNN save it? I am thinking that this saved version has some errors that was erronously deleting unconnected tables. Please help.

Is it possible to upload a new "version" of the module as well? Maybe that can include a corrected uninstall script? You might also simply be able to modify the manifest/module registration to remove that SQL reference.

I can't find anywhere that DNN might be storing the script on the file system, though I feel like I've recently seen that it does store the ZIP files somewhere after a module is installed.

The issue is resolved now. In case any one is wondering, the issue was couple of our custom modules are missing "basePath" value for script files in the dnn file, which caused the sql script files to be copied to base DNN folder instead of respective module folders and the last module that was installed has it uninstall sql script in the base DNN folder and when I uninstalled the module it was running the unistall script of the last module that was installed with the basePath issue. I tried changing the "manifest" column data (in packages table) directly in the database, but it didn't work for some reason. I had to install a update to the module that I was planning to uninstall with correct basePath so that it can run the correct uninstall script when I uninstalled it.
