It has come to my attention that several websites are offering a portable version of DiskTuna. As I was curious I downloaded a few. I advise NOT to download these versions as they seem to be installing unwanted software as well. They are typically offered as .RAR or .ZIP files and are larger than the 1.07 MB original setup offered on this official website. The files are typically hosted on file sharing sites offering a slow or delayed download option, or a fast and payed download option.
I did not create this portable setup. The setup created by me is 1.07 MB in size with the filename ‘DiskTuna_Setup.exe’ and is signed by ‘Joep van Steen’ (me).
