Affaire des fiches is a French phrase that means "affair of the files." It was a scandal in France in the late 1990s. In this scandal, it was discovered that the French government had been collecting information about citizens for years without their knowledge or permission. The information was stored in special files, or fiches, which is why the scandal was called "affaire des fiches" (affair of the files). The scandal caused a lot of outrage among the French people because the government was collecting information about them without their permission. The government had to stop collecting this information and apologize for the scandal.
