Does anyone know how to get a list of all removable volumes mounted with Swift?
I've already tried this, but it return a list of all files and subfolders of external drivers:
let filemanager:NSFileManager = NSFileManager()
let files = filemanager.enumeratorAtPath("/Volumes")
while let file = files?.nextObject() {
println(file)
menu.addItem(NSMenuItem(title: file as! String, action: Selector(""), keyEquivalent: ""))
}
This prints the list of all mounted volumes:
let filemanager = NSFileManager()
let keys = [NSURLVolumeNameKey, NSURLVolumeIsRemovableKey, NSURLVolumeIsEjectableKey]
let paths = filemanager.mountedVolumeURLsIncludingResourceValuesForKeys(keys, options: nil)
if let urls = paths as? [NSURL] {
for url in urls {
println(url)
}
}
You can of course filter to get only the paths inside the "Volumes" directory:
let filemanager = NSFileManager()
let keys = [NSURLVolumeNameKey, NSURLVolumeIsRemovableKey, NSURLVolumeIsEjectableKey]
let paths = filemanager.mountedVolumeURLsIncludingResourceValuesForKeys(keys, options: nil)
if let urls = paths as? [NSURL] {
for url in urls {
if url.relativePath?.pathComponents.count > 1 {
if url.relativePath?.pathComponents[1] == "Volumes" {
println(url)
}
}
}
}
And with Swift 2 there's two differences: pass []
instead of nil
for the filemanager's options, and there's no need to cast the array of NSURLs:
let filemanager = NSFileManager()
let keys = [NSURLVolumeNameKey, NSURLVolumeIsRemovableKey, NSURLVolumeIsEjectableKey]
let paths = filemanager.mountedVolumeURLsIncludingResourceValuesForKeys(keys, options: [])
if let urls = paths {
for url in urls {
if url.relativePath?.pathComponents.count > 1 {
if url.relativePath?.pathComponents[1] == "Volumes" {
print(url)
}
}
}
}
Update for Swift 2.1
let keys = [NSURLVolumeNameKey, NSURLVolumeIsRemovableKey, NSURLVolumeIsEjectableKey]
let paths = NSFileManager().mountedVolumeURLsIncludingResourceValuesForKeys(keys, options: [])
if let urls = paths {
for url in urls {
if let components = url.pathComponents
where components.count > 1
&& components[1] == "Volumes" {
print(url)
}
}
}
Update for Swift 3
let keys: [URLResourceKey] = [.volumeNameKey, .volumeIsRemovableKey, .volumeIsEjectableKey]
let paths = FileManager().mountedVolumeURLs(includingResourceValuesForKeys: keys, options: [])
if let urls = paths {
for url in urls {
let components = url.pathComponents
if components.count > 1
&& components[1] == "Volumes"
{
print(url)
}
}
}
