Are you sure its this line thats causing the trouble? Are you checking the returned pointer "file"? BTW, I think you are trying to write "/home/user...." whats the error message?

Code:
#include <stdio.h>
int main()
{
FILE *file = fopen("/home/usr/.app/save.txt","w");

fopen doesnt open this file and pointer is empty. I am sure that the file exists. Where is problem?

If you really have created a directory called /home/usr/.app (why would you do that?), then:
a) sorry
b) please don't release an app that writes to this crazy location
c) paste the output of the command
Code:
ls -l -R /home/usr/.app

OK, 2 more questions:
1) are you running the app as 'root', or as 'user'?
2) can you also paste the output of the command

As user.
drwxr-xr-x 2 root root 4096 Mar 1 18:35 /home/usr/.app
THX /home/user/.app is better?

if you do
Code:
chown -R user.user /home/usr/.app
