⑵MyDefrag.. 更新日志:
⑶Added the MoveUpToZonefileaction.
⑷Changed the NTFS scanner so it will now always use bytes for the USA fixup. Previously it used the number of bytes per sector, which is bytes for most harddisks, but it appears that NTFS also uses for ultra-big harddisks, even though they have a different number of bytes per sector.
⑸Added some code to SelectNtfsSystemFiles() to protect the program against infinite loops in data on the disk.
⑹Fixed a bug that caused MoveToEndOfDisk() not to display a progress percentage.
⑺Changed the ExcludeVolumessetting. It can now be used multiple times in a script.
⑻Documented the "/TASKS" installer mandline option.
⑼Added the SkipBlockoption to all the SortBy fileactions.
⑽Added the ExitIfTimeoutsetting.
⑾Added the bouncing box display mode to the screensaver.
⑿Added a special exclusion for the "$dcsys$" file used by DiskCryptor so MyDefrag will never move this file. The exclusion is not really needed because the file is protected by the DiskCryptor driver, but I have added it anyway, just in case.
⒀Changed the way how variables can be defined and changed. Previously the syntax was "NAME=VALUE", but this caused undesirable error messages in case of a syntax error. Variables can now be defined and changed with the SetVariablemand.
⒁Several improvements in error reporting. One of these is that the regular MyDefrag version will no longer ask the user to post the debug logfile on the forum.
⒂The ImportListFromProgramHintsfileboolean will now ignore hint files that are older than days.
⒃Changed the contents of the "date" variable from "//" into "--". The old contents could not be used for filenames.
⒄The installer will now create a daily scheduled task by default. Previously the default was not to create the task.
⒅Added the "DataDiskDaily.MyD", "DataDiskWeekly.MyD", "DataDiskMonhtly.MyD", "Daily.MyD", and "Monthly.MyD" scripts. Renamed the "OptimizeDaily.MyD" script into "SystemDiskDaily.MyD", "OptimizeWeekly.MyD" into "SystemDiskWeekly.MyD", and "OptimizeMonthly.MyD" into "SystemDiskMonthly.MyD".
⒆The installer now creates two scheduled tasks, a daily task and a monthly task.
⒇Fixed a problem in the ZoneSize and ZoneBegin script variables.
