To see how much space you have used and free
Start - All Programs - Accessories - Right click Command Prompt and choose Run As Administrator. Type (or copy and paste by right clicking in the Command Prompt window and choosing Paste).
For the system drive
wmic volume where (DriveLetter='%systemdrive%') get Caption, Capacity, freespace /format:list
For all drives
wmic volume get Caption, Capacity, freespace /format:table
If you want to store this info on your desktop
wmic /append:"%userprofile%\desktop\Free Disk Space Report.html" volume get Caption, Capacity, freespace /format:htable
To open double click Free Disk Space Report.html on your desktop or type
start "" "%userprofile%\desktop\Free Disk Space Report.html"
Then come back here after cleaning and repeat these commands to see the difference.
If for some reason the wmic command doesn't work use these two commands. Both take a long time.
defrag %systemdrive% -a
or
dir %systemdrive%\*.* /a /s
To see where files are taking up space
This will list the number of files and size for folders on your drive. Each command does a subset so you can manage it better.
Start - All Programs - Accessories - Right click Command Prompt and choose Run As Administrator. Type (or copy and paste by right clicking in the Command Prompt window and choosing Paste).
Then configure the command prompt. Right click the Command Prompt's titlebar - Properties - Layout tab - and enter 1000 for Screen Buffer Size Height and 43 (or 50) for Window Size Height. Change the Color (Color tab) and Font (Font tab) if you want.

for /f "skip=2 tokens=3" %A in ('Reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v "Personal"') do set doc=%A
for /f "usebackq tokens=2* delims= " %i IN (`dir "%doc%" /a /s ^|findstr /i /v "\/"^|findstr /l /v "Pictures Music Video"`) DO @echo %j&echo.
To see size of folders in Music.
for /f "skip=2 tokens=4" %A in ('Reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v "My Music"') do set Doc=%A

Disk Cleanup
The normal way to run Disk Cleanup is to right click the drive in My Computer (Start menu - Computer), then Properties - General tab - Disk Cleanup button.
Another way is Start menu - All Programs - Accessories - System Tools - Disk Cleanup.
Disk Cleanup can be started from the command line.
Start - All Programs - Accessories - Right click Command Prompt and choose Run As Administrator. Type (or copy and paste by right clicking in the Command Prompt window and choosing Paste).
To do your main drive.
cleanmgr %systemdrive%
To choose which drive to do.
cleanmgr
See the last section of this note to see how to supercharge Disk Cleanup.
System Restore
In Disk Cleanup above also see the More Options tab. You can delete all but the last System Restore point and see if that is taking up space.
System Restore uses 15% of the disk space normally. To change click Start - All Programs - Accessories - Right click Command Prompt and choose Run As Administrator. Type Regedit and navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\cfg
and double click DiskPercent and click Decimal and change the value to the percentage you want,
You can change it at the command prompt.
Start - All Programs - Accessories - Right click Command Prompt and choose Run As Administrator. Type (or copy and paste by right clicking in the Command Prompt window and choosing Paste).
To see size of System Restore folder.
You don't normally have access to this folder. You need to take ownership, give administrators permission, then query the size.
takeown /f "%systemdrive%\System Volume Information" /a /r /d y
icacls "%systemdrive%\System Volume Information" /grant Administrators:f /t /c /q
dir "%systemdrive%\System Volume Information" /a /s
To see current percentage
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\cfg" /v DiskPercent
It's hexadecimal. Numbers are 0-9 then a-f. So 0xf is 15. 0x5 is 5, 0x9 is 9, 0xa is 10, 0x14 is 20.
To set to a different value.
You can use decimal values to set it. This sets it to 10% (bolded in the example and the last item on the line).
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\cfg" /v DiskPercent /t REG_DWORD /f /d 10
To repair the System Restore folder delete it and restart System Restore.
sc stop vss
takeown /f "%systemdrive%\System Volume Information" /a /r /d y
icacls "%systemdrive%\System Volume Information" /grant Administrators:f /t /c /q

Compress Files
There are two ways to compress files in windows. Zip files and the inbuilt file compression. This is about the inbuilt file compression. Type zip in Start - Help and Support for more info on zipping.
Photos, music, and video are already compressed. They may get larger if Windows tries to compress them any further. Also usually a bad idea to compress system files.
If you have document or spreadsheet files they can be compressed very well. If you have folders of setup files they may also be good candidates. Web pages also make good candidates.
In Windows Explorer blue filenames means Compressed (this is file system compression not Compressed folders aka zip files). Green filenames means Encrypted.
To turn off coloured filenames, in Explorer - Tools menu (Alt + T) - View tab, and then clear the Show encrypted or compressed NTFS files in color check box.
Windows compression, encryption, and security work mostly by apply attributes to a folder, and files in the folder inherit from the folder.
If you have any folders suitable for compression find them in Explorer, right click them - Properties - General tab - Advanced button - Compress contents to save disk space. Choose to apply to all files and folders when asked.
To use a command line to compress the files in the Favorites folder.
Start - All Programs - Accessories - Right click Command Prompt and choose Run As Administrator. Type (or copy and paste by right clicking in the Command Prompt window and choosing Paste).
compact /c /s:"%userprofile%\Favorites" *.*
To set favourites to compress future files added
compact /c /s:"%userprofile%\Favorites"
To view compression details of the Favorites folder
compact "%userprofile%\Favorites\*.*"
Turn off Low Disk Space Warnings
To turn off the feature to show low disk space warnings.
Start - All Programs - Accessories - Right click Command Prompt and choose Run As Administrator. Type (or copy and paste by right clicking in the Command Prompt window and choosing Paste).
