Я адаптировал скрипт, опубликованный Apple16 выше, для запуска в Python 3 и немного его улучшил. Используя комбинацию выборочного исключения папок из истории файлов и этого сценария для просмотра возможных проблем, я сузил свою проблему до двух файлов с почти одинаковыми именами в одном каталоге. Оба файла имели слово Espanol в имени файла с тильдой над n. Однако у одного была кодировка: Espan\N {COMBINING TILDE} ol, а у другого - Espa\N {LATIN SMALL LETTER N WITH TILDE} ol. Оба имени файла одинаково перечислены в Проводнике Windows с тильдой над n. Когда я помещаю эти два файла в отдельные папки, они прекрасно сохраняются в истории файлов, но, находясь в одном и том же каталоге, они, похоже, мешают друг другу и блокируют работу истории файлов.
Вот скрипт CheckFileNames.py, который я использовал:
#CheckFileNames.py, 10 May 2016, LewisN
#Python 3 version adapted and enhanced by LewisN; based on script by apple16 posted on http://superuser.com/
#Scans Windows file system for potentially problematic directories and files affecting File History operation.
#---------------------------------------------------------------------------------
#SET THE FOLLOWING BEFORE RUNNING:
DirectoryTreeToScan = r'C:\Users\<username>'
DaysBackToList = 0 #Number of days back to list. Set to 0 to list all FLAGGED FILES regardless of file dates.
PrintDates = False #Set True to show File Creation and Modification dates.
#You may also want to play with the following settings:
flagDirLen=200
flagFullNameLen=200
# Max filename len on Windows is ~255, but File History adds "F:\FileHistory\<username>\<computer name>\Data" to
# the front the files and a timestamp to the end, so backing off on name lengths flagged to be safe.
# Files with long filenames are actually saved to F:\FileHistory\<username>\<computer name>\Data\$OF and can be
# retrieved using the File History GUI, but you may want to avoid this. Also there may be cases where
# long paths and/or filenames cause errors.
#Notes:
# 1. Filenames with Unicode characters from various languages are also often ok for File History.
# This script exposes these characters so they can be examined for potential problems.
# 2. Filenames with initial dots (also flagged here) are ok for File History (use cmd prompt to edit them).
