To shrink existing C drive on a new (unused) laptop

I want to shrink C partition on my new Lenovo laptop, to make space for two extra partitions.
- one for temporary downloads and the other for a possible virtual drive for testing
- the Lenovo is to replace an (ailing/unstable) 7 year old Toshiba

I have a bootable MiniTools (on DVD) to shrink the Lenovo C partition (with Windows OS inactive)
- I believe this is the only way normally unmovable files can be "relocated/moved" during the resize/shrink process

So far (out of the box) the Lenovo has not been used other than to register the OS with MS.
- no apps nor AV etc have been installed, it is a very clean machine.
- the default AV (Norton) has been uninstalled, but no defragging yet

Greg Rocker suggested Piriform's Defraggler. I would prefer a portable defragger at this point

Current usage on my old Toshiba is 111GB approx 20% of the usable C:\ drive space (images at end of this post)

My plan is to use unallocated space on the Lenovo for one or two other partitions
1. Downloads
2. Virtual drive for testing ( not sure whether SandBoxie in C: or a separate virtual drive/partition)

I think 100GB for C on the Lenovo would be more than ample because I now use an external USB HDD for data.
- I do use hibernation occasionally so adequate space would be required for that
- is my target of 100GB enough (on the Lenovo) for OS, apps, AV, hibernation etc ?

This is my first foray into partitioning the OS drive
- I have partitioned data drives in the past using installed MiniTools

Any comments about my planned sizing (or anything else) would be appreciated, thank you :)

You seem to be on top of things. No comments required.

As you have probaly guessed IT is not my strong point.

Your structure is very similar to my plans.
- downloads partition as a transition area, the same as your "Media" partition.

I'm curious why you keep your data on a USB drive? Is it an encrypted drive??

I know nothing about encrypted drives
... also ...
The external data drive is moved between multiple PCs, it holds AutoCad snippets, PC maintenance tips (and my VBA coding library). My memory is not as good as it used to be (a stroke last September wiped out a few brain cells), as an extreme user of TXT files FileSearchEX does a good job of finding file contents.
Vastly superior to trying to use a data-base and FSex has been the best contents finder (RegX searches) I have found.
4,700 TXT files at last rough count.

Imaging is my next project, hopefully this week.
- since Windows-3, PC maintenance was not a priority at all until about 3 years ago, when I had to start from a zero knowledge base. Win-7 was not an easy experience to start with.

I see you are using VirtualBox in a partition (Windows OS virtual drive ?)
- your layout is very similar to my plans

I would like to use Linux for browsing and email, but not dual boot, a pain to be rebooting between Windows and Linux. (I think ?) VirtualBox (? no experience yet)

The Lenovo is my first new laptop in 6 years
- 3 new off line machines in that time, always entrusted to paid gurus

~~ just personal preference, but since I image my disk periodically I've chosen to remove the Recovery Partition and reclaim its space. On the couple occasions when OS was corrupted, i restored the C partition from backup. Pretty quick recovery from a image of C vs. the recovery partition (Though i still keep a backup image of original disk with the recovery partition - just in case )

My plans also, learning how-to is the challenge.

Today I hope to shrink C: to 100GB using bootable MiniTool (already have ISO downloaded), if unmoveable OS files are not hogging space and limit the "shrink" process.
Defragging C: from a bootable drive is part of the plan but so far I cannot find one. GregRocker in 2009 was recommending Puran to defrag OS before boot, but lately he was touting the virtues of Defraggler. Now Greg is "Account Closed" so is not available for confirmation.

I am way out my league with defragging the OS, but I do use Mint on a stick to recover files from dead OS on other machines.

As a nervous-nellie I don't want to screw up the Lenovo. SevenForums is my lifeline

Thank you for your encouraging post :)
