I need to copy all the directories that do not match the pattern

Thank you for the code!
Do you think you could elaborate on why your snipped is working and my is not?
even if I add your regex it is not printing anything...
it seems exactly the same.

your code:

tofind = r'^[A-Z0-9]{8}_\d{4}$'
 
for d in ["_Y151029E_7345", "D151009EN_7295", "mydir","small_11","TST___3456","TST_3456","TST3456"]:
    if re.findall(tofind,d):
        print(f"{d} Matched")
    else:
        print(f"{d}  no match")

And I wrote (the directories names are the same):

import re
from pathlib import Path
tofind = r'^[A-Z0-9]{8}_\d{4}$'
for ed in Path('C:\\01\\TLogs').iterdir() :
    if ed.is_dir():
        rudir = Path(ed).parts[3]
        print(f" Dir_Name -{rudir}")
        if re.findall(tofind,rudir) :
            print(f" found -> {rudir}")
