📰 I used a password to encrypt some files a couple of years ago. I used some sort of software to do it, can't remember. I have the password for decrypting the files, but I don't know where to put in the password being that I do not have the old softwar

Allow me to elaborate more on my title. I used a file-encrypting software to originally encrypt these files onto a flash drive, mostly documents and photos. Completely forgot about them and cleaning my room today I found the old flash drive and would like to reopen whatever I had saved. Problem is, since then I have upgraded my computer many times, I am on a completely different startup disk, and cannot for the life of me find whatever software I had originally used to secure the files. I DID however find the long password I used that the software gave me to unlock it with. So, the question is, how can I recover these files if I don't have the original software? Is this password even useful without the software? Thanks.
