How can I retrieve a list of all drives on a Windows system using Go?

Retrieving a List of All Drives on Windows Using Go

Listing drives is essential when accessing data from multiple storage devices. In Windows, the GetLogicalDrives function provides a way to obtain a bit map representing the available drives.

To convert the bit map to a list of drive letters, follow these steps:

1. Call the GetLogicalDrives function and retrieve the bit map:

<code class="go">import "syscall"

driveBitmap := uint32(syscall.GetLogicalDrives())</code>

2. Convert the bit map to a list of drive letters using the bitsToDrives function:

<code class="go">func bitsToDrives(bitMap uint32) []string {
    var drives []string

    availableDrives := []string{"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"}

    for i := range availableDrives {
        if bitMap&1 == 1 {
            drives = append(drives, availableDrives[i])
        }
        bitMap >>= 1
    }

    return drives
}</code>

3. Iterate through the list of drives and perform the desired operation, such as searching for a specific file type:

<code class="go">drives := bitsToDrives(driveBitmap)

for _, drive := range drives {
    // Perform operation on drive
}</code>

By using this approach, your program can automatically iterate through all drives on a Windows system without requiring the user to specify drive letters manually.
