If your text file is not large:
with TStringList.Create do
try
LoadFromFile(yourFileName);
i := IndexOf(yourTextString);
if i > -1 then
Delete(i);
SaveToFile(yourFileName);
finally
Free
end;
With best regards, Mike Shkolnik

I have to search a text in a txt file and if I found it I have to delete the
row (the row does't have duplicate value, it is always unique) that match
the text founded.
Please give me a valid suggestion as soon as possible, thanks.

Ultimately, you must rewrite the file. There is no way to "squeeze" a
line out of it short of copying everything after the deleted line to
where the deleted line was. If you are using TStream's, the CopyFrom
method makes that easy.
Good luck.
