Ntfs file system properties

In order to get the Owner, you need to do a little more work, similar to what you are doing in your PowerShell script. You would use the FileInfo. GetAccessControl method, then call the GetOwner method. The code above assumes you have a struct or class named FileProperties that will be used to pass back the rows in a streaming TVF. Using this method, the values returned can and should be strongly-typed. Hence, you can populate your table as follows:.

And GetFileProperties can even be updated to accept an input parameter for the starting directory Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Edit: Could this all be combined to operate together in a single process? Improve this question. It is recommended that FAT16 is never used on any modern media. It is also compatible with many media devices such as TVs and portable media players. It is also referred to as Mac OS Extended.

The extended file system was created to be used with the Linux kernel. Connect and share knowledge within a single location that is structured and easy to search.

I want to detect if a file on disk was edited since last access, or restored since last deletion. Let's assume this isn't on a VM. Any modification to the file after this point will result in a hash mismatch. The file could be modified and then have its modification date manually restored to the previous value using SetFileTime, so a hash mismatch does not occur. This scheme is easy to overcome because all easily-accessible file access properties are mutable date of creation, modification, access, etc.

Do files within an NTFS file system have any immutable properties? Maybe an MFT sector index or something? In my actual use case I'm looking for a way to detect if a file has been restored after deletion. If you have full control on the filesystem, there are various possible tools, like the NTFS access properties which allow to say precisely what a user can do with a file or a directory.

You could also probably use audit events if you have full control on a system. But if the file is in a system that is controlled that the user, the most you can do is to use obfuscation technics , meaning hard to guess ways, but that can certainly circumvented by a voluntary user.

For example you could write additional data in different places on the filesystem and on the registry. If all are consistent, then the system is clean. This may be divided into several fragmentation as shown in the figure below, and if it is bad, performance will be degraded unless defragmentation is performed. Let's look at concrete tools. Install and launch the Active Disk Editor freeware, select "test.

Size is 0x Although this is confusing, 4 means the size of the first cluster cluster position 4 bytes , 1 means the size of Cluster count 1 byte. Since the sector start position is a large value of 20,,, it means that 4 byte size is required. Since Cluster count has a value of 1, I use only 1 byte. It is also used to add security information to.
