I was looking for a quick and easy way to get directory and file size for a given directory and its sub-directories. I came across a nice post by Luis Diego Fallus and ended up using a commenter’s code to produce output in MB format.
gci . | %{$f=$_; gci -r $_.FullName |
measure-object -property length -sum |
select @{Name="Name"; Expression={$f}} ,
@{Name="Sum (MB)"; Expression={ "{0:N3}" -f ($_.sum / 1MB) }}, Sum } |
sort Sum -desc | format-table -Property Name,"Sum (MB)" -autosize
Example Output
Name Sum (MB) ---- -------- Adobe 1,603.809 TestDirectory 67.715
Rob van der Woude has a nice batch script to get disk usage of folders & subfolders in Windows since there isn’t a built-in function. This could be similar to Linux du command.

Here’s a query I found that helps show database IO consumption.
SELECT
DB_NAME(DB_ID('DATABASENAME')) AS [Database Name]
, mf.physical_name
, io_stall_read_ms
, num_of_reads
, CAST(io_stall_read_ms / (1.0 + num_of_reads) AS NUMERIC(10, 1)) AS [avg_read_stall_ms]
, io_stall_write_ms
, num_of_writes
, CAST(io_stall_write_ms / (1.0 + num_of_writes) AS NUMERIC(10, 1)) AS [avg_write_stall_ms]

TAPEDRIVE NOTES (LINUX 2.4)
-Rich (01/08/2004)
Rewind tape drive:
# mt -f /dev/st0 rewind
Backup directory /www and /home with tar command (z – compressed):
# tar -czf /dev/st0 /www /home
Find out what block you are at with mt command:
# mt -f /dev/st0 tell
Display list of files on tape drive:
# tar -tzf /dev/st0
Restore /www directory:
# cd / # mt -f /dev/st0 rewind # tar -xzf /dev/st0 www
Unload the tape:
# mt -f /dev/st0 offline
Display status information about the tape unit:
# mt -f /dev/st0 status
Erase the tape:
# mt -f /dev/st0 erase
You can go BACKWARD or FORWARD on tape with mt command itself:
(a) Go to end of data:
# mt -f /dev/nst0 eod
(b) Goto previous record:
# mt -f /dev/nst0 bsfm 1
(c) Forward record:
# mt -f /dev/nst0 fsf 1
Replace /dev/st0 with your actual tape drive name.
What is it?
I created a small tool to help facilitate setting the default user to automatically logon to a system.
Requirements
- Administrator Privileges
- .NET 2.0 or greater
Details
There are 4 registry entries of interest here:
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogon] AutoAdminLogon=1 DefaultUserName= DefaultPassword= ForceAutoLogon=1
If you don’t want to download and run my program, you can simply copy the above text into notepad, save-as a .reg file and double-click it to run it. Make sure you take care to modify the settings as necessary.
The convenience of my application is that it will list local users so you can simply just click on the desired user and set the information accordingly.
