I'm not sure file recovery software will work here but it's worth a try (as the data file is stored as a .dat which is similar to .txt so doesn't have any defining signaures.
Also, if you have the wallet.dat file then copy that into the data directory and your wallet will be restored (although you may need to find where the seed and password is stored).
This thread is in the electrum subforum, so it is probably safe to assume hidolfo is using electrum, so he probably does not have a "wallet.dat" file
.txt (and similar) files are able to be recovered by some file software recovery programs; a quick google search came back with several results.
