Sorry, but what do you mean by "bitcoin file"? Do you mean the .dat files from Core wallet?
Assuming that the application is clean and that you are not seeking suspicious targets through it, who do you think would need it if he could ever use the core wallet and extract all addresses and see all transaction history?
I do not trust your intentions of issuing this application, and I suspect that it is malicious, but I am not a specialist in codes, and I cannot prove this technically.
I do not advise anyone to use any program to deal with any of the confidential data of Bitcoin savings, including the wallet, seed words, and any files that allow dealing with these savings. Please stay away from those online scammers!
