winapi - How to remove .zip file in c on windows? (error: Directory not empty) -

output is:

-------------------------- archive:  1234.zip   inflating: 1234/4.txt   inflating: 1234/56/5.txt   inflating: 1234/56/6.txt   inflating: 1234/1_23.zip -------------------------- 

your code looks feasible @ first glance, recursively clean directories before attempting remove them.

one thing comes mind, possibility have zip file opened in application, hence possibly locked.

you won't "directory not empty" errors unless, well, directory isn't empty.

for start, change line:

if(_rmdir(foldername) != 0)perror(foldername); 

to:

if(_rmdir(foldername) != 0) {     char buf[1000];     sprintf(buf,"dir \"%s\"",foldername);     system(buf);     perror(foldername); } 

and should tell directory you're in , offending files are.
