问题 While wandering the web looking for explanations of how to read/write MFT I found the folowing section:(http://www.installsetupconfig.com/win32programming/1996%20AppE_apnilife.pdf) If NtfsProtectSystemFiles is set to FALSE, then the special files can be opened. There are, however, some drawbacks associated with attempting to do this: Because many of the special files are opened in a special way when mounting the volume, they are not prepared to handle the IRP_MJ_READ requests resulting from a

Know the number of files / directories before doing a FSCTL_ENUM_USN_DATA

问题 Before doing a USN journal / NTFS MFT files-enumeration with while (DeviceIoControl(hDrive, FSCTL_ENUM_USN_DATA, &med, sizeof(med), pData, sizeof(pData), &cb, NULL)) { // do stuff here med.StartFileReferenceNumber = *((DWORDLONG*) pData); // pData contains FRN for next FSCTL_ENUM_USN_DATA } I'd like to know the number of files/directories (to "reserve" a std::vector: v.reserve(...) and also other reasons). I thought about using FSCTL_QUERY_USN_JOURNAL before, that gives a USN_JOURNAL_DATA_V0

These special files can be

问题 for some commercial project I'm doing I need to be able to read the actual data stored on the $mft file. I found a gpl lib that could help, but since its gpl i can't integrate it into my code. could someone please point me to a project that i could use / or point me at the relevant windows API (something that doesn't require 1000 lines of code to implement) BTW, why doesn't windows simply allow me to read the mft file directly anyway? (through the create file and the read method, if i want to

How to get the full path for USN journal query?

问题 I am trying to go through the example on MSDN (https://msdn.microsoft.com/en-us/library/windows/desktop/aa365736%28v=vs.85%29.aspx) on how to query USN journal in order to trace file changes on a NTFS drive. The example code works well. However, in this example code, the USN_RECORD structure only returns me a file reference number and the file name. It does not return me the full path of the file. Does anyone have any idea how to query USN journal to return a full path? Or there is a way to

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

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) + 0x10000] = { 0 }; // 64 kB while (DeviceIoControl(hDrive, FSCTL_ENUM_USN_DATA, &med, sizeof(med), pData,

How to get LBA(logical block addressing) of a file from MFT on NTFS file system?

问题 I accessed the $MFT file and extracted file attributes. Given the file attributes from MFT, how to get a LBA of file from the MFT record on NTFS file system? To calculate LBA, I know that cluster number of file. It that possible using cluster number to calculate? 回答1: I'm not entirely sure of your question-- But if you're simply trying to find the logical location on disk of a file, there are various IOCTLs that will achieve this. For instance, MFT File records: FSCTL_GET_NTFS_FILE_RECORD
