![]() ![]() Windows Explorer replaces empty disk names by Local Disk or similar, but UltraDefrag doesn't. On FAT disks space gets immediately released after file movements, so it might happen that more files get fully defragmented than initially calculated. Why the progress sometimes exceeds 100% for FAT disks? So it advances pretty quickly when the program deals with big files, and slows down significantly when thousands of small files are in the queue. The progress percentage measures disk space, not number of files. Why the progress percentage updates irregularly? Why configuration files are better than one settings window with tabs?Ĭonfiguration files are easy to edit, even in Windows Notepad. Maybe we'll implement the discussed feature later, but now it's time for more significant improvements. When defragmentation algorithms are quite efficient, it's definitely not necessary to know locations of individual files - anyway you'll get your drive optimized quite well. Graphical interface When will the cluster map become interactive, so I'll be able to know where individual files are located on disk? The only drawback is that in some cases a reboot may be required to release the assigned drive letter, especially on older systems like Windows XP. To automate the process the diskpart utility can be used as shown in the Console Interface chapter of this handbook. Then defragment it and, if you wish, remove the assigned letter afterwards. ![]() Go to Start > Control Panel > Administrative Tools > Computer Management > Storage > Disk Management and assign a drive letter to the volume. I have a volume with no drive letter assigned, how can I defragment it? This way UltraDefrag will move all files, regardless of their fragments size, to the beginning of the disk. Just set the fragment_size_threshold parameter to 0, the optimizer_file_size_threshold parameter to 15 EB and unset all filters. Usually it doesn't make sense to move big fragments, but if you'd like to get all files perfectly sorted or just want to pack everything as tight as possible before partition shrinking you can easily do it. How to move everything to the beginning of the disk? Due to this reason we recommend to use backup software instead to keep valuable data backed up. When it exhausts all the disk space reserved for restore points it eliminates elder stuff to release some space for further tracking. The system restore service sometimes tracks file movements. Then expand it back to the original size to get a continuous free space gap at the end.Īfter defragmentation I see my restore points disappeared, what happens? Use GParted or Partition Magic software to shrink the disk.Everything will be perfectly settled in the beginning of the disk. Move all files to another disk, reformat the original disk and move files back.If it fails to achieve the desired result try one of the following: To consolidate free space you can try the full optimization. General usage I need to defragment a large file but have no sufficient free space gap on the disk, what should I do? As a result your antivirus software will get fixed and you won't see the false positives anymore. We do recommend you to report the case to your antivirus software vendor. So, if you see a message saying UltraDefrag is infected by a virus, actually that's nothing but a false positive. Only when all files pass most of the virus scanners we make an official release. For extra safety, to ensure that the compiled binaries haven't been accidentally infected, we test them all carefully on. UltraDefrag is open source software, so it cannot contain malicious stuff by definition. My antivirus software says UltraDefrag is infected by a virus. There's no need to remove old files, the installer will take care about everything automatically. If it shows IA64 download the ia64 installer.Ĭan I up- or downgrade over an existing installation?.If it shows AMD64 download the amd64 installer.If it shows x86 download the i386 installer.check out the top-left corner of the opened command prompt window.type cmd.exe /K echo %PROCESSOR_ARCHITECTURE% and then click OK.Installation How can I find out which installer to download? ![]()
