Re: How safe is "Remove Data" Tool in 4.1.9?
It will remove all data.
My advice is never rely on X-Cart for anything data related including but not limited to imports, exports, backups, purging or indexing.
EDIT: Also never rely on the accuracy of the communication verbiage.
Great examples are when you try to mass remove products from a category and it deletes them from the database entirely or when you create a backup and it ignores every non-default table.
