  1. how to find out value of ‘c’ from equation here below in ‘excel’
    + 641.8 C = 76.5 C + 63.87 C + 16540744.5

  2. USELESS… just looks at the extension of the file…. says .txt is text, says .xls is spreadsheet, etc… does not read the file header to determine anything. I tested this.. just a joke/scam to get you to possibly purchase “other products”…. waste of time

  3. Great advertisement but you leave no way to download the program. Just another scam …. you should be ashamed.

  4. Thanks! I don’r know how many times I’ve tried in vain to try to figure out what a file was or where it was from to no avail! Many thanks from seattle!
