How to compare 2 volumes and list modified files?

阅读更多关于 How to compare 2 volumes and list modified files?

问题 I have 2 hard-disk volumes(one is a backup image of the other), I want to compare the volumes and list all the modified files, so that the user can select the ones he/she wants to roll-back. Currently I'm recursing through the new volume and comparing each file's time-stamps to the old volume's files (if they are int the old volume). Obviously this is a blunder approach. It's time consuming and wrong! Is there an efficient way to do it? EDIT: - I'm using FindFirstFile and likes to recurse the

Detecting if the target volume is NTFS using NSIS

阅读更多关于 Detecting if the target volume is NTFS using NSIS

问题 I'm creating an installer with NSIS for a program that needs to run on an NTFS volume. How do I detect if the install to path is on an NTFS volume and act accordingly (show a help/warning message)? 回答1: Using external tools is not always a good idea (Not every command line tool exists on the Home versions of windows ) It's always better to call the correct API directly with the system plug in. !include LogicLib.nsh StrCpy $0 "c:\" System::Call 'Kernel32::GetVolumeInformation(t "$0",t,i ${NSIS

阅读更多关于 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

阅读更多关于 Windows How to change or insert physical sector into another file?

问题 I have 20 files where the data structure is sector aligned to 4k in NTFS. I want to combine all files without copying any data . The goal is to write a sort of insert API that works by directly changing NTFS Virtual Clusters and Physical Clusters. The goal is to have a file sized 1TB all from 50GB chunks without copying. All data is already on the disk and on the same volume. This would work by directly setting the NTFS logical cluster inside the file. I can read the Virtual to Physical

问题 Does anyone know of any software that can extract the $bitmap file from NTFS images? Or does anyone know of any site that documents NTFS enough so that I can code this myself? (I want to read the $bitmap so I can identify what clusters are not in use, so they can be removed from the images.) 回答1: There's one short paragraph in this early publication by a talented person: http://www.alex-ionescu.com/NTFS.pdf 回答2: I answered this one in a different place, but on a live Windows machine the best

Is there an API to set a NTFS ACL only on a particular folder without flowing permissions down?

阅读更多关于 Is there an API to set a NTFS ACL only on a particular folder without flowing permissions down?

问题 In my environment, I have several projects that involve running NTFS ACL audit reports and various ACL cleanup activities on a number of file servers. There are two main reasons why I cannot perform these activities locally on the servers: 1) I do not have local access to the servers as they are actually owned and administered by another company. 2) They are SNAP NAS servers which run a modified Linux OS (called GuardianOS) so even if I could get local access, I'm not sure of the availability
