TrimTree 1.20

Unsupported utility to remove files from a complete directory tree if those files are older than a specified age. Intended for command-line in overnight batch jobs. Usage example:

@ECHO Delete the less interesting channels after 2 days
TrimTree 2 C:\MSG\images\ *-msg-ch06.* *-msg-ch07.*
@ECHO Delete the more interesting channels after 7 days
TrimTree 7 C:\MSG\images\ *-msg-ch02.* *-msg-ch09.*

In this example, files which are older than 2 days, living in the folder C:\MSG\images\ and below, which match either the file names for MSG HRIT channel 6 or MSG HRIT channel 7 would be deleted, and the files older than 7 days for MSG channels 2 and 9. This allows you to optimise disk storage by keeping the more interesting data for a longer period. The lines above would be entered into a command-file such as Nightly.cmd, and you would use the Control Panel, Scheduled tasks function to make Nightly.cmd run at, for example 03:05 in the morning. If your computer is not on 24 hours a day, you could make the task run when you start up the computer by putting a shortcut to the Nightly.cmd file in your Program File, Startup folder.
Here is a different example - to keep the log files from Ship Plotter, Plane Plotter and SBS-1 BaseStation software under control. ShipPlotter log files are kept for two weeks, and the aircraft-related files for seven days.

@ECHO Delete PlanePlotter and ShipPlotter log files
TrimTree 7 "C:\Program Files\COAA\PlanePlotter\log files\" pp*.log
TrimTree 14 "C:\Program Files\COAA\ShipPlotter\log files\" sp*.log
@ECHO Delete SBS-1 BaseStation log files
TrimTree 7 "C:\Program Files\Kinetic\BaseStation\" 20*.bst
