One report is that "Compare It" is a renundant copy of FREE "WinMerge"References: EXE file properties Home | https://www.grigsoft.com/wincmp3.htm Q:: ¿ how when the program is discontinued ?
Redundant copy of WinMerge, with much worse features and UI. Author goes around spamming negative reviews for open source apps even though this is not a free program.
