Python Folders Splitter to Files Splitter

[Guybrush16bit]

The folder naming seems to work initially but fails to update correctly after a certain poin,especially with the ZX Chip Vologodonsk files.
The counter variable might not be resetting properly after each folder is created.
Fix counter so it reset to 0 after every filesperfolder files, ensuring a new folder is created consistently.

from pathlib import Path
from shutil import move

# Get the current working directory as a Path object
wd = Path.cwd()
files = [f for f in wd.iterdir() if f.is_file()]
lastitemindex = len(files) - 1
results = Path(wd.drive) / "/c64Romset_output"
filesperfolder = 5  # Set to 5 for testing; adjust as needed
letterstodisplay = 15
results.mkdir(parents=True, exist_ok=True)

# Open log file
log_output = (results / "log_output.txt").open("w+")
tally = 0
counter = 0
folder_index = 0
for i, file in enumerate(files):
    tally += 1
    # Create a new folder (reached filesperfolder limit)
    if counter == 0:
        start_idx = i
        end_idx = min(i + filesperfolder - 1, lastitemindex)
        firstfn_2l = files[start_idx].name[:letterstodisplay].split("(")[0].strip().upper()[:4]
        lastfn_2l = files[end_idx].name[:letterstodisplay].split("(")[0].strip().upper()[:4]
        target = f"{firstfn_2l} to {lastfn_2l}".strip()
        (results / target).mkdir(exist_ok=True)
        print(f"Created new directory: {target}")

    # Move the file to the target folder
    newfname = file.name.split("(")[0].strip()
    move(file, results / target / newfname)
    print(f"Moved {file.name} to {results / target} as {newfname}")
    log_output.write(f"\nMoved {file.name} to: ** {target} ** as {newfname}")
    counter += 1
    # Reset counter and prepare for the next folder
    if counter == filesperfolder:
        counter = 0
        folder_index += 1

if __name__ == "__main__":
    print(f"{tally} files processed ... ALL DONE")
    log_output.write(f"\

Gribouillis code is better and work for me if i do one change.

from pathlib import Path
from shutil import move

# Get the current working directory as a Path object
wd = Path.cwd()
# Setup output directory and parameters
# add one /
results = Path(wd.drive) / "/c64Romset_output"
filesperfolder = 5  # My test set 255
letterstodisplay = 15
# split list of files into chunks
files = [f for f in wd.iterdir() if f.is_file()]
chunks = [files[i : i + filesperfolder] for i in range(0, len(files), filesperfolder)]

# function to shorten names
def short(name):
    return name[:letterstodisplay].split("(")[0].strip().upper()[:4]

log_output = (results / "log_output.txt").open("w+")

tally = 0
for files in chunks:
    target = f"{short(files[0].name)} to {short(files[-1].name)}".strip()
    print(f"{tally} files processed ... making new dir called: {target}")
    (results / target).mkdir(parents=True, exist_ok=True)
    for file in files:
        # Move the file to the target folder
        newfname = file.name.split("(")[0].strip()
        move(file, results / target / newfname)
        print(f"Moved {file.name} to {results / target} as {newfname}")
        log_output.write(f"\nMoved {file.name} to: ** {target} ** as {newfname}")
    tally += len(files)


if __name__ == "__main__":
    print(f"{tally} files processed ... ALL DONE")
    log_output.write(f"\n{tally} files processed.")
    log_output.close()

I just tried the new Griboullis one, another time an error:

Error:

Your code Snappsat appear to work as expected, now, however he trunks filnames and extensions. Randomly some file remain with extension even if their name is very log, sometimes the code trunk the name even if it is short.
Obviously I don't need the name to be truncated :-( The file name should be exatly the same as the original one...
Many thanks if you should fix this last problem

Letters to display is related to how many long must be the name of the folder (example for selecting 5 is AAAAA to BBBBB) but the file name must not be changed

Tried also to set Letterstodisplay to 100, but the result is not changed, as you can see names are truncated randomply and folders are always 4 to 4 digits (AAAA to BBBB):
