ssd - Low disk space on drive C with Windows 10


I have a "haier laptop y11b" it have 2 disks:



  1. SSD card of 29 GB, C drive on which windows 10 is installed

  2. HDD 465 GB


Previously Windows 8.1 was installed on this laptop and all the apps were installed on drive D. It was fine, showing no problems. There was always 13 GB or more free space available on C.


Then I installed windows 10. After installation on drive C, 15 GB was still free.


Then due to low space on C, I installed all of my apps on drive D, but space was still occupied on drive C. And now only 938 MB is free on C, and its marked red with error "low space on c".


Now I don't understand what is consuming drive C's space in windows 10, while there was no such problem with windows 8.1. How do I free out the space on C, while only windows 10 is installed there?



I downloaded WinDirStat and scanned C. I found a few large folders and files:



  • Windows\WinSxS = 8.0 GB

  • Windows\Installer = 3.1 GB

  • ProgramData\Package cache = 1.2 GB

  • pagefile.sys = 1.4GB

  • hiberfile.sys = 803MB

Can I delete or move any file to other drives just to free up space on my SSD?



Answer



pagefile.sys is an important Windows file. Delete that, and your computer won't restart. So you'd rather not delete it. ;)


This article explains WinSxS: http://www.thewindowsclub.com/winsxs-folder-windows-7-8


So basically, there is a way to clean the WinSxS folder. You might want to run the Disk Cleanup tool that comes with Windows or download a cleanup tool, such as CCleaner. From there, do not forget to uninstall useless apps and delete files you do not use.


There is also ways to tell your computer to install every apps automatically on your drive D:.



To change the registry, follow these steps:



  1. Start Registry Editor by entering Regedit in the search All programs.

  2. Locate the following: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

  3. Right click on the value named ProgramFilesDir & change the default value C:\Program Files to the path you want to install all your programs in.

  4. Click OK and Exit.

Assuming you are using a Windows 10 64-bit, make this change as well:



  1. Press the Windows key + R on your keyboard type regedit and press Enter key.

  2. Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

  3. Change the Path in DWORDs ProgramFilesDir, ProgramFilesDir (x86) to the new path.


Little reminder


This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756: How to back up and restore the registry in Windows



If you'd like to move Windows Apps, follow these steps:



  1. Press Windows key + I on your keyboard

  2. Go in System, then Storage in the left menu

  3. Select new Path in New apps with save to (Refer to picture)

You can also Move already installed apps. The procedure is almost the same.



Press Ctrl + I to bring up the Settings menu. Now click System, then select Apps & features (Or Installed Apps) from the left-hand navigation.


Here you will find a list of all apps and programs installed on your system. Note that this move method will only work for apps that you have installed – that means those which were pre-installed can’t be moved.


Scroll to the app that you want to move and select it from the list. Now, click Move. Select the new drive location from the dropdown, then click Move.

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

linux - Extract/save a mail attachment using bash

Using normal bash tools (ie, built-ins or commonly-available command-line tools), is it possible, and how to extract/save attachments on emails? For example, say I have a nightly report which arrives via email but is a zip archive of several log files. I want to save all those zips into a backup directory. How would I accomplish that? Answer If you're aiming for portability, beware that there are several different versions of mail(1) and mailx(1) . There's a POSIX mailx command, but with very few requirements. And none of the implementations I have seem to parse attachments anyway. You might have the mpack package . Its munpack command saves all parts of a MIME message into separate files, then all you have to do is save the interesting parts and clean up the rest. There's also metamail . An equivalent of munpack is metamail -wy .

performance - Single Threaded Qaud Core v.s Hyper-Threading Dual Core

Let's say we have two CPUs, One is Quad Core 3.2 Ghz with 4 Cores, and We have a Dual Core 3.2 Ghz with 2 Cores with 2 threads in each Core (Hyper-Threading). My assumption as a programmer will be, the 4 cores 4 threads should perform faster than 2 cores 4 threads since the second CPU needs to switch between threads in order to emulate 4 cores while the first one doesn't need to perform such switching as each core can perform independently and individually. I want to confirm that my assumption is true, if not please explain why one is better than the other. Answer I do believe thats true - since hyper threading does share some elements - specifically the main execution resources, you'll be able to run 4 full threads at once, rather than waiting for those resources to be freed up. The point of HT is to get better performance with a smaller use of die area - your quad core would generally be a bigger chip - say almost twice as large, than a non HT dual core chip, while a HT...

freeze - How do I stop windows 8.1 from freezing when the screen locks

This happens to me on a regular basis if I leave the computer for upwards of 10 minutes. It didnt do so at first but started after a couple of days. This is possibly related to further windows updates although nothing seems to tie in obviously when looking at my update history. I have to hold the power button in to power off. If the screens have switched off aswell they wont come back on, if they haven't I see the login picture and can move the mouse pointer but nothing happens and no combination of keyboard mashes or mouse clicks lets me see the login prompt. In the event log (type event viewer into the start menu) under system before every Critical problem (me powering down the machine without restarting) I get distributedCOM errors talking about this guid: "The server {BF6C1E47-86EC-4194-9CE5-13C15DCB2001} did not register with DCOM within the required timeout." I also get the same error for this 1B1F472E-3221-4826-97DB-2C2324D389AE. This seems to be a common theme and...
