Ho .memo file sul mio PC dallapp memo predefinita su un telefono Samsung di proprietà precedente. Quando vengono aperti in Blocco note, i file non contengono testo normale. Come posso recuperare il contenuto dei promemoria?
Risposta
Utilizzando VLC player o scaricando Samsung Note per PC come indicato qui

Ho scritto il mio convertitore “memo2txt” in Python. Ecco lo script (prima dovrai installare le librerie Python usando pip ):
import os import re import glob import zipfile import xmltodict from datetime import datetime MEMO_PATH = r"i:\MY\PROGRAMMING\AndroidMemoExtracter\MemoFiles" RESULTS_PATH = r"i:\MY\PROGRAMMING\AndroidMemoExtracter\Results" memos = glob.glob(MEMO_PATH + "\*.memo") for i, memo in enumerate(memos): print("{}/{} - {}".format(i+1, len(memos), memo)) try: # Extract *.memo file and read the content archive = zipfile.ZipFile(memo, "r") memo_content = archive.read("memo_content.xml").decode("utf-8") cleanr = re.compile("&.*?;") memo_content = re.sub(cleanr, "", memo_content) memo_content = xmltodict.parse(memo_content) text = memo_content["memo"]["contents"]["content"] # Generate filename from memo timestamp timestamp = int(memo_content["memo"]["header"]["meta"][2]["@createdTime"][:10]) date = datetime.fromtimestamp(timestamp).strftime("%Y-%m-%d %H-%M-%S") file_name = "{}.txt".format(date) # Save file as a *.txt with open(os.path.join(RESULTS_PATH, file_name), "w", encoding="utf-8") as file: file.write(text) except zipfile.BadZipFile: continue Answer
ispirato da beeshyams, ecco la mia versione …
sul mio Samsung J3, i memo sono in un drive MTP da qualche parte come …
SAMSUNG Android/Phone/ShareMemo/*.memo
lxml sorgente ha un aspetto simile a questo:
