Tables related to products? Quick mass delete?

[mmx]

Hello everyone!

I would like to ask what the related to the products tables are..

I need a way to mass delete ALL the products but not the categories..

If I write an sql query that deletes everything from the tables that have in their name the word "product" would that be safe? Or I am going to break anything?


Extra info:
The reason I need to do this is that I wrote a program that uploads massively products to my eshop.. The thing is that I do not have any option to check if the products already exists.. so what I do for now is to delete the products manually from the VM2 admin panel.. and then run my program.


Thanks in advance!
