Trying to get MFT table from Python 3

偶尔善良 提交于 2020-02-02 13:57:07
问题 I try to read MFT table from my local disk from python. Of course, if I write something like this: input_file = open('C:\$MFT', "rb") I will get [ Errno 13] Permission denied: 'C:\$MFT' I tried to use pyMFTGrabber, but it doesn't work; I got a lot of "socket.errors". What the best and easy way to read this file, using Python? Maybe it is some WinAPI, or something else? After reading I want to analyze it with "analyzeMFT" 回答1: It's rather painful with python, since it's not exactly low-level.

Can the NTFS $MFT file have child records?

问题 I am writing some code to parse through the MFT on disk in NTFS volumes. This is straightforward, but one particular corner case caught my eye, and I can't find a clear answer anywhere on the internet. For normal files in NTFS it is possible to have multiple MFT records for a single file, if the file has more attributes than can fit in a single record (for example, many $FILE_NAME attributes if the file has many hard-links, or many $DATA attributes if it has many Alternate Data Streams). The

Implement Change Journal in Delphi

问题 I'm seeking to use Change Journal instead of ReadDirectoryChangesW to track changes in my delphi XE2 application (as for why: ReadDirectoryChangesW is not that reliable) The closest I could find in delphi/pascal is something called Delphi MFT/Journal helpers, it contains two pascal units: uMFT.pas and uDevNotification.pas. The code above deal with MFT (very nicely actually), but nothing as far change journal goes. I also found this C# code, which seems to do what I want, only it's in C# My

Finding a set of file names quickly on NTFS volumes, ideally via its MFT

假如想象 提交于 2019-12-28 13:56:13
问题 I am in the middle of writing a tool that finds lost files of an iTunes library, for both Mac and Windows. On the Mac, I can quickly find files by naming using the wonderful "CatalogSearch" function. On Windows, however, there seems to be no OS API for searching by file name (or is there?). After some googling, I learned that there are tools (like TFind , Everything ) that read the NTFS directory directly and scan it to find files by name. I would like to do the same, but without having to

Why file enumeration using DeviceIoControl is faster in VB.NET than in C++?

匆匆过客 提交于 2019-12-23 04:28:43
问题 I am trying to read windows Master File Table (MFT) for fast enumeration of files. Till now I have seen two approaches to do this: As suggested by Jeffrey Cooperstein and Jeffrey Richter using DeviceIoControl Direct parsing of MFT as presented in some opensource tools and An NTFS Parser Lib For my project I am focusing on the approach [1]. The problem I am facing is mostly related to execution time. Just to be clear, following is my system and development enviornment: IDE - Visual Studio 2013

Speed up NTFS file enumeration (using FSCTL_ENUM_USN_DATA and NTFS MFT / USN journal)

问题 I'm enumerating the files of a NTFS hard drive partition, by looking at the NTFS MFT / USN journal with: HANDLE hDrive = CreateFile(szVolumePath, GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, NULL, NULL); DWORD cb = 0; MFT_ENUM_DATA med = { 0 }; med.StartFileReferenceNumber = 0; med.LowUsn = 0; med.HighUsn = MAXLONGLONG; // no change in perf if I use med.HighUsn = ujd.NextUsn; where "USN_JOURNAL_DATA ujd" is loaded before unsigned char pData[sizeof(DWORDLONG) +

Master File Table cleanup utility? [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . Can anyone recommend a tool for MFT cleanup? I want to in my MFT restore the entries for files which once existed but have been deleted to a "pristine" state, with zeroed out entries. 回答1: This paper by Hal Berghel and David Hoelzer lists a whole bunch of products which claim to securely erase files.

How to dump the NTFS $Bitmap file

南笙酒味 提交于 2019-12-10 18:06:34
问题 For a project, I want to get the list of all free/used clusters on an NTFS partition. For this i have to dump the $Bitmap file and parse its contents. There are few API's and examples on the web, but however they don't seem to work. Is there a simple way/ code sample to just copy the $Bitmap file somewhere. Is using FSCTL_GET_VOLUME_BITMAP the only way? Ideally I would like to do it in C#. 回答1: NFI.EXE which is (used to be) part of the "oem support tools" can enumerate all NTFS partition
