Detect Storage Card Root Folder Name

[Guest]

I am writing an application in C# and I was wondering if there is a
way to detect the name of the storage card folder, specifically if its name
is "SDMMC Disk" or "Storage Card" this way I can grab that folder name no
matter what it is and use it in another string to locate a file on the
Storage Card.

Thanks

All storage cards are root level folders with the Temporary attribute, see
Alex's code here to list all the storage cards on the system:-

Keep also in mind that you'll get a system mounted ROM storage(s) if it's
present on the device. For example on HP devices there is \IPAQ File Store
that'll be treated exactly the same as storage card. Unfortunately I was not
able to find a certain way to indentify the one vs. another.

The same effect happens on our devices, also, where on-board FLASH is
mounted as filesystem entries, but there's no way, other than knowing that
it's present, to know that it's persistent.

This worked great! thanks for the help.
I tested it on an Intermec Device and got the correct foldername
However I am not sure if it is correct on the IPAQ Device as Alex mentioned.
I am getting back the IPAQ File Store but I am not sure if that is correct.

Thanks Again Peter.

Thanks for the response, I am using an IPAQ and I do infact get back the
\IPAQ File Store but I am not sure if this is the actual storage card or not.

Do you know how I can do a Cold Boot on the IPAQ so that I loose everything
on the device except the OS and necessary files?

Thanks

Below is the Code I used to Find the Root Folder Name of the SD Card and put
it in to an arraylist so that I can show it to my app.

DirectoryInfo rootDir = new DirectoryInfo(@"\");

FileAttributes attrStorageCard = FileAttributes.Directory |
FileAttributes.Temporary;

ArrayList myAttr = new ArrayList();



foreach( FileSystemInfo fsi in rootDir.GetFileSystemInfos() )
{


if ( (fsi.Attributes & attrStorageCard) == attrStorageCard )
{
//Found storage card
myAttr.Add(fsi.FullName.ToString());
}
}

for(int i=0; i<myAttr.Count; i++)
{
string pStorage;
pStorage = myAttr.ToString();

if(pStorage == @"\SDMMC Disk")
{
txtresult.Text = pStorage;
}
}

//The above code is finding the root folder name of the SD Card of an Intermec
//Hand Held Device, which the foldername we know ahead of time is SDMMC Disk
