please add a free space defragmenter. The algorithm should be something in between Full and Quick optimization. Should compact the free space all at the end, moving files (fragment or not) that are isolated, to the first possible free space after the main used block. Inner sectors of a disk are faster access, so keep most of the files near the inner is always best.

    more, having only one big free space at the end, eliminate the risk of fragmentation on newly created files.

    Quick optimize is already moving not fragmented files to the beginning of the drive, so this will be closed.

    this RFE is about "free space defragmenter" not on "not fragmented files to the beginning".
    I do not think those two things are related. For example I just run Quick optimize on two partitions, and a lot of files are left in between free space at the end of partition, so free space is not defragmented.

    I cannot attach shots probably as the RFE is closed

    There is a size limit, so make sure the files don't exceed this limit.

    partitionD quick defragmented

    now I could upload the shots of the two partitions quick defragmented.
    Look, there are many holes of space left in between files (fragmented or not, doesn't matter)

    Did you already try the repeat action?

    In some situations the process must be repeated multiple times, since the free space region is fragmented by unmovable files.

    Could you post a debug log file of an analysis of both drives, so we would know what your settings are.

    I'm trying to repeat, sure is not good, we have to repeat the process, UD algorithm should end when no further improvements are possible.

    Looking at he images, seems impossible to me all the red files are unmovable. Ok some can for Windows system folder, but on partition D are all not system files.

    Can you please explain me how con I extract the debug log file?
