How to modify a list of filenames in a specific way?

Dear Matlab community,
I have a fairly simple question for you experts. I'd like make a column taking just the first part of a file name (string):
e.g. This is what I have
names =
"vul1_4_9.txt"
"bat1_1_1.txt"
"chy1_1_16.txt"
"chy1_1_17.txt"
"g6_1_18.txt"
"stcv1_1_1.txt"
"ser1_3_4.txt"
And I'd like to have instead a column just with the names before the first "_" :
names=
"vul1"
"bat1"
"chy1"
"chy1"
"g6"
"stcv1"
"ser1"
So far, I was able to "substract" the ".txt" part of the file name using the following loop:
names_n = length(names)
for id = 1:names_n
[~, f,ext] = fileparts(names(id));
rename = strcat(f - '_*_*') ;
names_new = [names_new;rename]
end
Obtaining this output:
names_new=
"vul1_4_9"
"bat1_1_1"
"chy1_1_16"
"chy1_1_17"
"g6_1_18"
"stcv1_1_1"
"ser1_3_4"
How should I proceed?

S = ["vul1_4_9.txt"
"bat1_1_1.txt"
"chy1_1_16.txt"
"chy1_1_17.txt"
"g6_1_18.txt"
"stcv1_1_1.txt"
"ser1_3_4.txt"];
Z = extractBefore(S,'_')
