I am using Stata 11.2 and am looking for a routine that will look for all of the .dta files in my specified directory and remove them once I have completed my analysis as a clean-up exercise. 

I am using the code below after I have run my regression analysis, to list and combine my datafiles created following the regression analysis, but I cant seem to find out how I can remove all of the unwanted .dta files after I have exported the master analysis as a .csv file. This is important as I will then go on to use the code below after another set of regressions saved in the same directory, and I don't want to combine regression results from different sets of analysis. Is there a way I can amend the code below to remove all the files:


cd c:\test1
! dir *.dta /a-d /b >c:\test1\filelist.txt

file open myfile using c:\test1\filelist.txt, read

file read myfile line
use `line'
save master_data, replace

file read myfile line
while r(eof)==0 { /* while you're not at the end of the file */
	append using `line'
	file read myfile line
file close myfile
sort label2 analysis
rename estimate odds_ratio
drop order axis 
order label2 analysis  odds_ratio  min95 max95 stderr z p flag parm
save master_data, replace
rm c:\test1\filelist.txt
outsheet using C:\test1\results\Section1.csv,c replace
