file wallet without information

[menga28]

in 2018 I created several folders, they were nested and obfuscated, today I found a folder "ripple wallet" with a "wallet" file without extension, I opened it with the windows notepad and it is 773 characters, including two terminals "==", would anyone be able to tell me how to use this string? Unfortunately I didn't leave any indication in the file or directory, and the hierarchy doesn't help much. Could someone be kind enough to give me some info?
