Add the word “Figure”/"Table" to lof/lot: Past solution alters format

Question

I am new to the forum. Hopefully my question is within standards.

I want to add the word “Figure”/"Table" in front of each caption in the lof/lot. I tried this solution: https://tex.stackexchange.com/a/155202/124927

And it worked perfectly. Well, almost.

The thing is that now the format in my lof/lot is slightly altered. It messes up the indentation in the captions that are long enough to require two lines, as in:

I am aware of the package tocloft. The problem is that the simple fact of loading it (as [subfigure]{tocloft}) in turn messes up the formatting of the lof and lot. The formatting needs to be consistent in all of the thesis.

I am using a customized class (not report , etc.) for the formatting of my school (created by somebody some time ago) which starts like this:

\NeedsTeXFormat{LaTeX2e}[2009/09/24]
\ProvidesPackage{sgpPhDstyle}

Is there any way to keep the solution in https://tex.stackexchange.com/a/155202/124927, while keeping the formatting of the lof/lot? Maybe a clever re-definition of \listoffigures?

Thanks a lot in advance to anybody that can give me an answer.

EDIT2: Ok, here is a MWE:

    \documentclass{article}
    \usepackage{tocloft}
    \begin{document}
    {
    \let\oldnumberline\numberline
    \renewcommand{\numberline}{\figurename~\oldnumberline}
    \listoffigures
    }   
    \addcontentsline{toc}{chapter}{List Of Figures} 
    \cleardoublepage

    \begin{figure}[!ht]
    \caption{this is a really loooooooooooooooooooooooooong figure captionthat will take up two lines in the List of Figures.} 
    \end{figure}
    \end{document}

Answer 1

tocloft provides better ways to use such a figure prefix, but the best way is to use caption and defining a new caption list format for figure and table.

\documentclass{article}
\usepackage{caption}
\usepackage[nottoc]{tocbibind}
\usepackage{tocloft}
\addtolength{\cftfignumwidth}{30pt}% More space
\addtolength{\cfttabnumwidth}{30pt}% More space


\usepackage{pgffor}

\DeclareCaptionListFormat{figprefix}{#1\figurename~#2}
\DeclareCaptionListFormat{tabprefix}{#1\tablename~#2}

\begin{document}
\tableofcontents
\cleardoublepage
\listoffigures
\listoftables


\captionsetup[figure]{listformat=figprefix}
\captionsetup[table]{listformat=tabprefix}


\foreach \x in {1,...,10} {%
  \begin{figure}[!ht]
    \caption{this is a really loooooooooooooooooooooooooong figure caption that will take up two lines in the List of Tables.}
  \end{figure}

  \begin{table}[!ht]
    \caption{this is a really loooooooooooooooooooooooooong figure caption that will take up two lines in the List of Tables.} 
  \end{table}


}
\end{document}
