Auto-Unzip to Desktop Program

This is a super simple C program to auto-unzip .zip files to your desktop thus saving you the effort of clicking through 4 or 5 dialog boxes to get to the uncompressed files.

You will need to have the decompression utility 7-ZIP already installed. Download from http://www.7-zip.org/download.html or SourceForge.

The Code:

Here is my C code for calling up the command line version of 7-ZIP and passing an argument. The main difficulty of this method is that you may get passed a path containing spaces. Thus you must loop through all the arguments and then place them in quotes before passing on to 7-ZIP.

#include <stdio.h>

int main(int argc, char *argv[])
{
  // Edit the path below so it specifies the 
  //location where you placed 7za.exe
  char line[400] = "C:\\Progra~1\\7-Zip\\7za.exe x \"";
  int i;
  for (i=1;i<argc;i++)
  {
     strcat(line, argv[i]);
  }
  // Change this to the short path to the desktop. 
  strcat(line, "\" -oC:\\Users\\Steven~1\\Desktop
      -aoa"); 
  system(line);
  return 0; 
}

After you compile, go to the browser and change your .zip preferences to open with our new helper program. If all goes well, the next time you try to open a zip file on the web, it to be automatically extracted to your desktop.

Other Notes: You may wish to add a new system command in the program to create a folder on the desktop to hold the extracted files.
