How do I setup Task Scheduler in Windows 7 to compress a folder using 7-Zip File Manager?

"You would need to create a Windows Batch file that will do that actually ZIP, and then schedule this in Task Scheduler to run on a weekly schedule.

The 7-Zip command-line samples are available here and a step by step guide to Windows 7 Task Scheduler is available here. Lastly to create a batch file use notepad and create a new file with a .BAT extension as follows

@echo off
[7zip command line here]

Save the file somewhere on your drive and point the scheduled task to it. Complete details on batch files are available here."
