A very good tool for fast defragmentation of individual files or folders. When working with large media files (audio and video) it is possible to make all the files contigous stored on a dedicated media drive. Defraggler is also a very useful companion to other defraggers - please keep it simple, safe and fast in your forthcoming versions. However, a nice feauture would be some options for directory placement, both in NTFS and FAT32. These files are normally locked by windows, how are the handled by Defraggler? I have not seen any problems with Defraggler so far. I think any problems other users had can originate from former use of windows defragger. Keep up the good work!
