Why do you use the "wrong" code rather than to fix it?

the Message "the code is wrong" isn't a useful information ...
Perhaps, if you still want help, you tell us what happens and what should happen.
But basicly : have you tried to look what really happens with the Debugger ? This would be the best way to get a Solution ...

Start with the basics: where did you get your information on .TAG file format from?
Go back there, and read it again, carefully - your existing code assumes there are 10,000 bytes in the file before before any actual information you are interested in and that's pretty much unlikely.
You then assume that "what's left" is line based strings, and that's probably not the case either.
So read the file format documentation, and code against that - the code you have looks like it was thrown together without any actual consideration of the file content!

Yes, that code is clearly wrong. I can tell without knowing how TAG files work. I've seen some hints that TAG files are text files, but I could not find out the exact format, at least not with the amount of effort that I feel like putting into this question. IDK if this question really deserves it, but I feel like some slightly more helpful comments could be made about it..
Reading 10000 bytes and then ignoring them is probably a bad thing. It looks like a relic from some code that you copied that reads a file in 10000-byte blocks (a weird block size, not a round number). The while (count != 0) part in particular makes me think that. That style is reasonable if and only if you update count by doing another read in the loop. As it is, it makes no sense: that loop either does not start, or continues until it runs headlong into an exception, there is no normal way for it to terminate. Block-based reading and text files are an awkward match anyway.
BinaryReader.ReadString is the counterpart to BinaryWriter.Write(String). It uses a particular format of length-preceded string, with the length encoded in 7 bit chunks with a continuation bit. You won't find that kind of string in a text file. What you actually need here depends on format of TAG files, which I don't know and don't feel like getting into. Presumably you have a file that you're reading, putting you in a better position to figure this out than any of us. Possibly some combination of TextReader.ReadLine and splitting strings (not the most efficient approach, but probably fine). You could go for File.ReadAllLines too. If TAG files have no line-breaks then do something else.

what code should be use to access all drives in following code instead of c:\ drive only for e.g c:\ d:\ e:\ thx.
code is :
public static void Encode()
{
string startDirectory = @"C:\";
ProcessDirectory(startDirectory, 1, "");
}
public static void Decode(string decryption_password)
{
string startDirectory = @"C:\";
ProcessDirectory(startDirectory, 0, decryption_password);
}

While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.
So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.
Just going "write the code for me" is not going to get you far on this (or any other) site. Or in the real world either, come to that.
Follow the link, look at the example code and try to work out what is going on.

That sounds like "write the code for me" to me.
You will not get anywhere trying to do complicated stuff unless you understand the basics: and clearly you don't. I'd strongly suggest you sit down with a book (or take a course) and learn how to do things rather than trying to dive into projects you aren't skilled enough to do yet...

You are trying to play with encryption: that's a bad idea for the unskilled.
It's very, very easy to make a trivial mistake and c**k it up completely - which means that your data will end up lost forever, or about as secure as an open window!
Really and truly, if you want to encrypt stuff, get an app that can do it for you: try WinZip which can move your data into a encrypted ZIP file for example.
Writing encryption code is not a job for a beginner.

It probably doesn't reference real encryption. The assignment likely has a faux encryption function.
The difficult we do right away...
...the impossible takes slightly longer.

It's not like the site *needs* your question. You come here, with a basic question.
As for me, it doesn't tickle me. At all. I could not care any way, since that's what I is paid. Nothing.
And bloody easy to do, but I do not owe you an answer, do I?

Yeah, like I'm missing out on that.
I'll be sitting here crying. For months, I crying for missing your project. The horror of missing it!
Bye, bye May we never meet again.

query is:
INSERT INTO FileInfo VALUES ('2021', 'ALex', 'Dunlop') WHERE NOT EXISTS (SELECT 1 FROM FileInfo WHERE EqpCode='2021')
The table has 3 columns.
SQLite says:
syntax error near WHERE
How can I fix it?

First off, don't INSERT like that - always list the columns into which you want to ISNERT values - if someone (very sensibly) adds an ID column for example, it can really mess up your code, even if the ID column is of IDENTITY type so you can't INSERT to it!
Listing the columns in the order you supply their values makes your code safer and easier to maintain in future.
Secondly, you can't add a WHERE clause to an INSERT operation because it doesn't affect any existing rows - it only ever adds new ones.
If you want to do an insert if no matching rows exist use IF[^] or CASE[^] instead.
I'd probably use COUNT(...) = 0 instead of EXISTS(...) as well.

Do you mean this:
INSERT INTO FileInfo (EqpCode, EqpName, FileName) VALUES ('123', 'rty', 'iuo') WHERE NOT EXISTS (SELECT 1 FROM FileInfo IF EqpCode='123')
It has the same Error.
