I'm not sure, if you understand what TFindDialog is. It is only a
dialog. It has no search capabilities.

Using grep for search might be ok.
A TMemo is a visible control and almost always slower than a
TTextStrings, TStringList, TSynEditLines or TCodeBuffer.

There are several ways to find the target files.
And there several ways to search a text in a file.

What exactly do you want to do?
