Affecting allocationSize in NTFS RRS feed

  • Question

  • I have an application writing 10 large files, one per thread, to an NTFS volume having 64K clusters.  It appears that NTFS allocates contiguous disk space to each file in 1MB chunks.  I would like to allocate large chunks, such as 100MB.

     

    I can do this programatically, but is there any external way to affect NTFS behavior such as with a registry setting?
