You're wasting your time trying to open these files in a text editor and find anything useful... they're binary data files.
As far as I can tell, the .tlb is most likely a "Type Library Binary" refer: https://docs.microsoft.com/en-us/windows/win32/com/type-library-viewers-and-conversion-tools
It just contains information on the various programming language objects that the application used and the various functions/methods that could be called. It is not a wallet and will not contain any wallet information.
The .dat file is likely also a binary file of some description... but it is impossible to say what the data format is... .dat is a very generic extension that a lot of different applications use to store data in. I doubt it is the same format as a "wallet.dat" from Bitcoin Core... and I would guess that the similarity between what you see in the text editor and an "ECDSA" key is just coincidence.
It *might* be some form of Base64 encoded text... but without seeing the full data it is impossible to tell...
In any case, you'd likely need the original application executable to do anything meaningful with these files... and it appears you only have the data files and not the application itself and I cannot find any reference to any "Bitsave" wallet application on the web.

Can i have Bitsave support email or something please ?
That other user doesn't have the contact details for this "Bitsave"... they were just offering general advice for how to recover your account. However, if the website is closed as you said, then you won't be able to email them anyway as the entire domain is likely long gone. 
What are the names of the 2 files in your "Bitsave" folder?

The first thing to do is write the most detailed and correct letter to the technical support of the service that provided you with the wallet and generated the key. Then, having already received an answer from them, it is worth following the instructions and not inventing some incomprehensible ways to solve the problem. Most often, technical support goes to a meeting in such situations. I myself lost my key, but thanks to normal communication with technical support and providing all the information that was asked of me, I got access to the wallet again. Everything is real, but without haste and panic.

I've tried a few, and it looks like any 64 character hex number above 0 is accepted.
Any 64 character hex number between 1 and n-1 will be accepted, with n being the order of the secp256k1 curve which bitcoin uses.How see mining transactions if i see no btc in btc explorer ? with electrum ?
If you see no transaction on a block explorer such as https://btc.com, then importing to Electrum will make no difference as it will show the exact same zero balance. If there are no transactions on the address you have ended up with, then either you have no bitcoin or you have landed on the wrong address.

Maybe I lost them but I have files name "Bitsave" with 2 files in it ? Can I recover from it ? Or its lost too cause I see website closed...
its working on bitadress
Never mind that, it is already correct above. Hexadecimal addresses will work on bitaddress, even if you use random hexadecimal numbers and alphabets. But, if not the one you sent bitcoin to, you will not see anything. If it did not work while converting it to WIF using bitaddress, that means it is not a valid private key.
I've tried a few, and it looks like any 64 character hex number above 0 is accepted. The address (probably uncompressed) may be empty though.
How see mining transactions if i see no btc in btc explorer ? with electrum ?
I invested in 2010 2011
How exactly did you "invest"? Do you just remember "buying some BTC" or something? The point of my line of questioning is trying to figure out what wallet you might have used... or where you might have bought the BTC from so that you can figure out exactly what these 32 characters are... and whether or not the 2 sets of 32 characters need to be put together to make a 64 character HEX private key... or if they're something else entirely.
Without knowing exactly how you got the BTC, or where you had stored it... these 32 hex characters may have nothing at all to do with BTC...
So, where exactly did you find these 32 characters? were they written down on paper? where they in an email? are they marked as "BTC Key" or with some other notes to indicate that they're actually related to Bitcoin?
Or did you just find 32 random hex characters somewhere and you just believe that they're related to Bitcoin because you "invested in 2010 2011"? they're actually related to Bitcoin, i mined.

I tried but i have nothing maybe its mining ? i need to put private key it in bitcoin core ? or Electrum ?
Did you mean it does not work while you use bitaddress offline? Because the hexadecimal private key with you will need to be converted to WIF, when wanted to convert it, it does not work? Or you are importing the hexadecimal directly? If it did not work while converting it to WIF using bitaddress, that means it is not a valid private key.

If it's really your own private key, you should try to remember what exactly you did back then.If it did not work while converting it to WIF using bitaddress, that means it is not a valid private key.

According to what OP posted already, he had two different 32 characters that are in hexadecimal. So, if taken together, it will be 64 characters, which could be a hexadecimal private key. I think OP should have tried that out, run bitaddress offline to generate the WIF to know if it will work.

Hello guys i found my old private key with 32 digit and number how can i convert it to wif import format ? thank you
What makes you think that this is a Bitcoin Private key? Was it written on a piece of paper (or in a text document etc) labelled "Bitcoin Private Key" or something similar (like a paper wallet printout etc)? Or was it just 32 hex characters that you had noted down somewhere?
Are there any notes or indications as to what software/system these 32 characters came from?If you can identify where these 32 hex characters from, you might have a better chance of figuring out how it leads to a private key.

I have another one with 32 number and letter starting with 02e9
just concatenate the two parts together and enter it in bitaddress.org (download the source from github and run it offline). once with first part first and the other time second
