Just override the models delete method:

import os
class File(models.Model):
    title = models.CharField(max_length=400, help_text="Enter the title of the file, this will appear on the listings page")
    CATEGORY_CHOICES = (
        ('Image', 'Image'),
        ('PDF', 'PDF')
    )
    file_type = models.CharField(choices=CATEGORY_CHOICES, help_text="Please select a file type", max_length=200)
    file_upload = models.FileField(upload_to=get_upload_to)

    def delete(self, *args, **kwargs):
        path=self.file_upload.path
        os.remove(path)
        super(File,self).delete(*args, **kwargs)

This will work only deleting the entity, not with bulk_delete. If you want to handle those within the admin view, you will have to create a default admin action like this:

from django.contrib import admin
from models import *


def delete_selected(modeladmin, request, queryset):
    for element in queryset:
        element.delete()
delete_selected.short_description = "Delete selected elements"

class FileAdmin(admin.ModelAdmin):
    model = File
    actions = [delete_selected]

    list_display = ('title', 'file_type')

admin.site.register(File, FileAdmin)

Hope it helps!
