Okey print( cur.rowcount ) shows each time a select a fialenme from the 
html table for downlaod that update affected 1 row.

Checking the database records instantly shown that in fact the counter 
was increased by +1

Runing files.py turn all counter values to 0.

So, update works, its the reload of files.py the deleets the values.

# Delete those database records that do not exist as filenames inside 
the path
for rec in data:
	if rec not in filenames:
		cur.execute('''DELETE FROM files WHERE url = %s''', rec )

# Load'em
for filename in filenames:
	try:
		# try to insert the file into the database
		cur.execute('''INSERT INTO files (url, host, lastvisit) VALUES (%s, 
%s, %s)''', (filename, host, lastvisit) )
	except pymysql.ProgrammingError as e:
		# Insertion failed, file already into database, skip this, go to next 
filename
		pass

These lines i dont how but they "manage" not to maintain the counter's value

What is now proved was at first only imagined!
