Hi, I have a data set of 200 files in a folder and each file look similar to this;

Code:
* Example generated by -dataex-. To install: ssc install dataex
clear
input str7 MONTH byte(com10553 com14898 com7435)
"2008-01"  6 0 0
"2008-02" 10 0 0
"2008-03"  8 0 6
end
I want to reshape it like the following;
Date Firm Value
2008-01 com10553 6
2008-02 com10553 10
2008-03 com10553 8
2008-01 com14898 0
2008-02 com14898 0
2008-03 com14898 0
2008-01 com7435 0
2008-02 com7435 0
2008-03 com7435 6
How can I reshape all the 200 files located in a folder using a single command?
