(C++) Detecting USB Drive by Thomas Roccia
Created the Sunday 19 March 2023. Updated 1 year ago.
Description:
This code uses the GetLogicalDrives function to retrieve a bitmask of all available drives on the system, and the GetDriveTypeA function to check if each drive is removable. If a removable drive is detected, the code prints its drive letter to the console.
Code
#include <windows.h>
int main() {
UINT drives = GetLogicalDrives();
for (int i = 0; i < 26; i++) {
if ((drives & (1 << i)) && GetDriveTypeA((char)('A' + i) + ":\\") == DRIVE_REMOVABLE) {
printf("USB drive detected: %c:\n", 'A' + i);
}
}
return 0;
