Windows edb delete - comprehensive reference
Is it safe to delete Windows EDB file?
It is safe to delete the Windows. edb. But after you delete it, Windows will take a while to re-index the files and rebuild the index, so your searches may be a bit slow till this job is completed.15 mei 2018
Hello, I'm going to show you how to find folders that are too large in WINDOWS. Go to your filesystem drive, C: in my case. Now check each folder size.
Program files (64-bit apps) and Program files (x86) (32-bit apps) are not the problem. Maybe you have some games in these two folders = large files, you can delete old games using the uninstaller or the CCleaner software. These two folders are where you have all of your system utilities and games, so it's not strange to see larger folders. (Program Files & Program Files x86) These two folders are not a problem, but maybe you can clean something up with the app uninstaller (it's your decision) Some folders are only on my PC (pcsx2 is the PS2 emulator / vstplugins are virtual musical instruments etc) ...) The WINDOWS folder contains the WINDOWS system files, so don't touch it. (15-20-25 GB) THIS IS THE REAL PROBLEM HERE: THE 'USERS' FOLDER In the 'users' folder you can check the size of the folders.
In my case I only have one user 'lok'. In my 'user folder' lok you can check all folders. The user folder also contains the downloads, documents, articles and hidden files.
Most home folders are normal in size. Maybe the download folder is bigger. Check your downloaded files, you may be able to delete something.
TIP: The Documents folder may contain Adobe Premiere cached preview files. Documents -> Adobe -> Premiere pro ---> Adobe Version -> (Adobe Audio Preview and Video Preview) .You can delete the folders for Adobe Audio Preview and Video Preview BUT THE MOST IMPORTANT FOLDER IS HIDDEN files in The user's folder you can go to 'View' and mark 'Hidden files' or you can activate this in the control panel.
You can also activate the hidden files in the file explorer on 'View'. Now a new folder has appeared 'AppData' this is the hidden folder. Now let's check the size ... wow 51GB ... this hidden file is too big ... 'AppData' always contains 3 folders and yes ..
Appdata contains application data files, you can't delete all of these folders as these folders are needed for many software like Chrome or others. But the problem with these folders is the cached files like Premiere cache files or iOS backups. You can analyze all of these subfolders, but be sure to delete files.
Check the size of each folder to analyze an anomaly. A subfolder larger than 5GB could be an anomaly, I think this 'temp' folder with large files was an old bug that was fixed in newer builds of Windows and I think you can delete it by clicking clean the system unit. Right click on C / Properties / General / Disk Cleanup / Mark Temporary Files and watch for Downloads.
But it's an old mistake because I've never seen it again. The most problematic folders are the Adobe folders when roaming --- common. The Common folder contains cached files.
You can delete the entire folder, it will be recreated with a new Adobe Premiere project. You must always check this folder, maybe there is a way to delete the cached files from the Adobe Premiere software as well. The other problem in this hidden folder is the iOS system backups.
Perhaps you have tried salvaging some iOS system files with third party software that clones all of your iPhone or iPad data in your 'appdata' folder. Manually check all of your folders to spot size anomalies backup, if you don't want the backups you can delete them, but if you want to keep your information you can copy these files to an external hard drive and delete them from your c drive. Paste the files into the same directory again if you want to restore the iOS system or whatever.
On the right in the c-driver properties you can activate 'Disk Cleanup' to also clean up the temporary files. And it was all ... greetings
What is Windows EDB used for?
edb is the Windows Search index database. A search index allows users to quickly search for data and files in the file system due to indexing of files, e-mails in PST files and other content.
Hello, I'm Carrie Anne and welcome to the computer science crash course. In the last episode, we just built a simple ALU using logic gates that performs arithmetic and logical operations, hence the 'A' and the 'L'.But of course, there's no point computing a result just to throw it away - it would be useful to somehow store this value and maybe even perform several operations in a row.
This is where computer memory comes in! In the middle of a long RPG campaign on your console, or when you're making your way through a difficult level with Minesweeper on your desktop and your dog stumbled by, tripped and pulled the power cord out of the wall, you know the agony of losing all of your progress. Sympathy. But the reason you lose it is because your console, laptop, and computers use random access memory, or RAM, which saves things like game status - as long as the power is on.
Another type of memory called persistent memory can survive without power and it is used for various things; We'll talk about persistence of memory in a later episode. Today we're starting small - literally by building a circuit that can store ... a single ... piece of information.
After that, we'll scale, and build our own memory module, and we'll combine it with our ALU the next time we finally build our own CPU! INTRODUCTION All of the logic circuits we've discussed so far go in one direction - always fluid - like ours 8-bit ripple adder from last episode. But we can also create circuits that loop back on themselves. Let's try taking a normal OR gate and feeding the output back into one of its inputs and see what happens.
First, let's set both inputs to 0. So 0 OR 0 is 0, and so this circuit always outputs 0. If we were to flip input A to 1.1, OR 0 is 1, so the output of the OR gate is now 1.
A fraction of a second later, it loops back into input B so that the OR gate sees that both inputs are now 1,1 are OR 1 is still 1 so there is no change in the output. If we reverse input A back to 0, the OR gate will still output 1. So now we have a circuit that records a '1' for us.
Unless we have one tiny problem - this change is permanent! No matter how hard we try, there is no way we can get this circuit to jump back from a 1 to a 0. Now let's look at the same circuit, but with an AND gate instead. We start inputs A and B both at 1,1 AND 1 outputs 1 forever.
But if we then turn input A to 0 because it is an AND gate, the output goes to 0. So this circuit records a 0, the opposite of our other circuit. As before, no matter which input we apply to input A later, the circuit always outputs 0.
Now we have circuits that can record both 0s and 1s. The key to making this a useful memory is to combine our two circuits into something called an AND-OR latch. It has two inputs, a 'Set' input that sets the output to a 1, and a 'Reset' input that resets the output to a 0.
If set and reset are both 0, the circuit only outputs what was last entered. In other words, it remembers a single bit of information! Memory! This is known as a 'latch' because it relates to a certain value 'Latched' and stays that way. The action of putting data into memory is called writing, while getting the data is called. is called reading.
Ok, so we have a way to store a single bit of information! Great! Unfortunately, having two different wires for input - set and reset want a single line to input data is a bit confusing we can set it to either 0 or 1 to save the value. We also need a line that will allow the memory to either be available for writing or to be 'locked' - what is known as a write enable line. By adding a few extra logic gates we can build this circuit called a gated latch as the 'gate' can be opened or closed.
Now this circuit gets a little complicated. We don't want to have to deal with all the individual logical gates ... so we'll still add a level of abdominal traction and put our entire gated latch circuit in one box - a box that stores a bit.
Let's test our new component! Let's start everything with 0. If we switch the data line from 0 to 1 or 1 to 0, nothing happens - the output stays at 0. This is because the write enable wire is switched off, which prevents any change in the memory.
So we need to 'open' the 'gate' by turning the write enable wire to 1. Now we can a. put 1 on the data line to store the value 1 in our latch.
Notice how the outcome is now 1. Success! We can switch off the enable line and the output remains at 1. Again we can toggle the value on the data line anything we want, but the output remains the same.
The value is stored in memory. Now we switch the enable line back on. Use our data line to set the latch to 0 - it works! Of course, computer memory, which only stores a bit of information, isn't very useful - definitely not enough to run Frogger.
Or really something. But we're not limited to using just one latch. If we put 8 latches next to each other, we can store 8 bits of information like an 8-bit number.
A group of latches that does this is called a register, which holds a single number and the number of bits in a register is called a width. Early computers had 8-bit registers, then 16, 32, and today many computers have 64-bit wide registers. To write to our register we need to first have all of the latches, we can do this with a single wire connected to all of their enable inputs which we set to 1.
We then send our data over the 8 data wires and then set enable back to 0, and the 8-bit value is now stored in memory. Setting latches next to each other works fine for a small number of bits. A 64-bit register would require 64 wires leading to the data pins and 64 wires leading to the outputs.
Luckily we only need 1 wire to activate all the latches, but that's still 129 wires. For 256 bits we have 513 wires! The solution is a matrix! In this matrix we don't line up r latches in a row, we put them in a grid. For 256 bits we need a 16 x 16 grid of latches with 16 rows and columns of wires.
To activate a latch we need to turn the appropriate row AND column wire on, let's zoom in and see how this works, we want only the latch at the intersection of the two active wires to be activated, but all other latches should be deactivated We can use our trusty AND gate for this! The AND gate only outputs a 1 if the row and column lines are both 1. So we can use this signal to uniquely select a single latch. This row / column setup connects all of our latches to a single common write enable wire.
In order for a latch to be write enabled, the row wire, column wire, and writable wire must all be 1. That should only ever apply to a single latch at any given time, wire for data. Since only one latch is ever write activated, only one stores the data - the rest of the latches will simply ignore values on the data line as they are not write protected.
We can use the same trick with a read enable line to read the data later to get the data from a particular latch. For a total of 256 bits of memory, this means we only need 35 wires - 1 data wire, 1 write enable wire, 1 read enable wire, and 16 rows and columns for selection. That saves a lot of wire! But we need a way to uniquely specify each intersection city where you might want to meet someone on 12th Avenue and 8th Street - that's an address that defines an intersection.
The latch in which we just saved our bit has an address of row 12 and column 8. Since there is a maximum of 16. gives lines we store the line address in a 4-bit number. 12 is 1100 in binary form.
We can do the same for the column address: 8 is 1000 in binary form. So the address for the particular latch we just used can be 11001000. To convert from an address to something that selects the correct row or column, we need a special I component called a multiplexer - the computer component with a pretty cool name, at least compared to the ALU.
Multiplexers come in all different sizes, but since we have 16 lines we need a 1 to 16 multiplexer. It works like this: give it a 4-bit number, and it connects the input line to a corresponding output line. So if we pass 0000, the very first column will be selected for us.
If we pass 0001 the next column is selected and so on. We need a multiplexer for our rows and another multiplexer for the columns. Ok, it's getting complicated again, so we're making our 256-bit memory its own component.
Another new level of abstraction! 8-bit address for input - the 4 bits for the column and 4 for the row. We also need write and read enable wires. And finally, all we need is one data line that can be used to read or write data. even 256-bit memory isn't enough to do a lot, so we'll have to scale even more! g to line them up.
Just like with the registers. We're making a series of 8 of these so we can store an 8-bit number - also known as a byte. To do this, we feed exactly the same address into all 8 of our 256-bit memory components at the same time, and each one stores one bit of the number.
This means that the component you just created can store 256 bytes at 256 different addresses. Leave this inner complexity behind. Instead of looking at this as a series of individual memory modules and circuitry, let's look at it as a unified bank of addressable memory.
We have 256 addresses and at each address we can read or write 8-bit value. We will use this memory component in the next episode when we build our CPU. The way modern computers scale to megabytes and gigabytes of memory, is to do the same thing as we did here - further packing up small bundles of memories in larger and larger and larger arrays.
As the number of storage locations grows, our a addresses will have to grow too. 8 bits contain enough numbers to hold 256 bytes of our memory addresses, but that's all. To address a gigabyte - or a billion bytes of memory - we need 32 -Bit addresses.
An important property of memory is that we can access any memory location at any time and in random order. This is why it is called Random Access Memory or RAM. When you hear people talk about how much RAM a computer has - that's the computer's memory.
RAM is like someone's short-term or working memory, keeping track of what's happening - whether you've had lunch or paid your phone bill. Here is an actual RAM stick - with 8 memory modules soldered onto the board. If we carefully open one of these modules and zoom in, the first thing you would see is 32 memory squares.
Zoom into one of these squares and we can see that each is made up of 4 smaller blocks. If we zoom in again, we come to the matrix of the individual bits. This is a 128 by 64 bit matrix.
That is a total of 8192 bits. Each of our 32 squares has 4 matrices, so that's 32 thousand, 7 hundred and 68 bits. And there are a total of 32 squares.
So all in all that's about 1 million bits of memory in each chip. Our RAM stick has 8 of these chips, so in total this RAM can store 8 million bits, also known as 1 megabyte. That's not a lot of memory these days - this is a RAM module from the 1980s.
Today you can buy RAM that has a gigabyte or more of storage - that's billions of bytes of storage. So today we built a piece of SRAM - Static Random-Access Memory - that uses latches. There are other types of RAM such as DRAM, Flash memory, and NVRAM.
These are very similar in their function to the SRAM, but use different circuits to store the individual bits - for example with different logic gates, capacitors, charge traps or memristors. But basically all of these technologies store bits of information in massively nested arrays of memory cells. The basic operation is relatively simple .. it's the layers of abstraction that are overwhelming - like a Russian doll that keeps getting smaller and smaller.
See you next week, credits
How do I reduce the size of my Windows EDB file?
In order to do it, first, open Control Panel >> Indexing Options >> Advanced >> click Rebuild (to open this dialog box, run the following command: Control srchadmin. dll ). Within a few minutes, the Windows Search will complete a full reindex of the data on the system drive. This will reduce the size of the edb file.
How do I delete Windows Search database?
You have two ways to delete the Windows Search index file: by deleting it explicitly in File Explorer, or by using the Indexing Options 'Advanced Options' dialog to rebuild the index, which first deletes the existing file before it rebuilds it.
