![]() I have no link, nor no interest, with team developping Wiztree. Knowing that (in more….) WizTree is (from far !) the fastest tool in its analysis phase, there is no photo : Since I discovered it, I gave up all the tools I used before (like WinDirStat) and use only WzTree now. Only WizTree provides the accurate disk space used. The release of WizTree 4.00 changes that, as it is now possible to scan multiple drives at once. – WizTree say that C:\Windows is 28.8 Gb, but “only” 19.0 Gb “allocated”Ģ8.8 Gb is actually the sum of all files sizeĢ3.1 Gb is actually the size of all ‘allocated’ files size (lower because some files are stored compressed, and then less space than their nominal size is allocated on the disk)ġ9.0 Gb is the same, but counting only once “hard linked” doubloons, triploons, etc…Īnd 19.0 Gb is the disk space actually used by C:\Windows.Īs a result, for me GDU is clearly wrong (I don’t where its value come from), and TreeSize free is partially wrong. ![]() – TreeSize free says that C:\Windows is 28.8 Gb, but “only” 23.1 Gb “allocated” – GDU says that my C:\Windows uses 29.2 Gb (which is WRONG) Any subsequent files that are hard linked to that original file get flagged as zero allocated space. In the questionWhat are the best power user tools for. The only limitation of WizTree is that when such hard link exist, it has to “grant” the disk usage to one of the “copies” (and count others as 0), and it is not “manageable” to define which one is privilegied :ġ) to be effective, WizTree has to be launched as admin, and on the drive itself (not on a directory a/o sub-directory)Ģ) the first instance of a file WizTree finds in the $MFT file gets the “allocated” space. When comparing WinDirStat vs WizTree, the Slant community recommends WinDirStat for most people. This is in particular widely used by Windows files, a lot of them being defined once in C:\Windows\system32\… and once C:\Windows\winsxs\…. ![]() files defined several times in the structure, but sharing the same data, present only once on the disk. Why this difference : Because Wiztree (and only Wiztree) manages “hard links”, ie. This means that such very small files, called resident files, do not occupy their own space on the hard disk.At least on Windows, among the three tools mentioned here (TreeSize, WizTree and GDU) only ONE provides accurate view of disk usage…. The content of very small files with a limit of about 900 bytes is simply stored in the MFT entry belonging to the file, in the so-called descriptor. But this is not true, because the developers of the NTFS file system have come up with something exciting. Now, one could conclude: If a file is only a few bytes in size, does it therefore always occupy at least one block? That would be quite a waste of space.

The space for this management information cannot be easily freed - not even by deleting the files, so it is not included in the occupied space calculated by our products.

WizTree has a relatively clean layout to it, and it’s pretty easy to understand how it works. The size of a cluster can vary depending upon several factors, including what file system is used (. WizTree is a disk space analyzer that lets you quickly and easily get a better understanding of what exactly is taking up space on your computer. The MFT is automatically enlarged if necessary, but never reduced in size. Disk space is allocated to files in units called clusters. Typically, one block is occupied here for each file. This is called Master File Table (MFT) in the Windows file system. This includes above all for the list of contained files together with their metadata. The file system itself requires additional space for administrative information. To understand this, we need to look again at how the file system works. Why is this sum smaller and what is occupying the remaining space? ![]() If you sum up the used space of all files, as TreeSize does, you will notice that this sum is smaller than the used space Windows reports for the hard disk. This is a quick and easy way to gain disk space. Our storage managers TreeSize and SpaceObServer can even apply NTFS compression to multiple files at once or entire directory branches.
