08:47:58 Path = C:\Program Files\MyDefrag v4.3.1\Scripts\AnalyzeOnly.MyD
08:47:58 Title = Analyze only
08:47:58 Description = Analyze the selected disk(s). The script will write a report to the 'MyDefrag.log' file, and will automatically pause between disks so you can view and interpret the diskmap.

08:47:58 Ignoring script because it has no Title or no Description.
08:47:58 Found: AutomaticMonthly.MyD
08:47:58 Ignoring script because it has no Title or no Description.

08:47:58 Path = C:\Program Files\MyDefrag v4.3.1\Scripts\ConsolidateFreeSpace.MyD
08:47:58 Title = Consolidate free space
08:47:58 Description = Move files and directories to the beginning of the disk(s). This can be useful on very full disks, to make room for manouvering big files. The script will move everything to the beginning of the disk, beginning with files at the end of the disk. It will fragment files to create parts that exactly fill gaps.
08:47:58 Found: DataDiskDaily.MyD
08:47:58 Path = C:\Program Files\MyDefrag v4.3.1\Scripts\DataDiskDaily.MyD
08:47:58 Title = Data Disk Daily
08:47:58 Description = Fast defragment and optimize the selected disk(s). This script is designed for every day use on data disks (all disks except the C: disk). It moves a minimum of data on the harddisk and finishes very quickly, but will not defragment extremely large files and will not fill all the gaps on the disk.

The script will place the MFT and the directories at the beginning of the disk, followed by a gap, and then it will defragment all the files and fast-fill all the gaps (consolidate empty space).
08:47:58 Found: DataDiskMonthly.MyD
08:47:58 Path = C:\Program Files\MyDefrag v4.3.1\Scripts\DataDiskMonthly.MyD
08:47:58 Title = Data Disk Monthly
08:47:58 Description = Thoroughly defragment and optimize the selected disk(s). This script is designed for occasional use, for example once per month. It will sort all the files by their full path, and will therefore take a long time to finish.

The script will place the MFT and the directories at the beginning of the disk, followed by a gap, and then it will sort all the files by their full path. This will also defragment all the files and fill all the gaps (consolidate empty space).
08:47:58 Found: DataDiskWeekly.MyD
08:47:58 Path = C:\Program Files\MyDefrag v4.3.1\Scripts\DataDiskWeekly.MyD
08:47:58 Title = Data Disk Weekly
08:47:58 Description = Defragment and optimize the selected disk(s). This script is designed for data disks (all disks except the C: disk), and is a compromise between the Daily and Monthly scripts. It will more thoroughly defragment files and fill gaps than the Daily script, but will not sort files like the Monthly script.
