问题 Given a drive letter, how do I get the OSImage InstallTo Partition ID and Disk ID without using the registry? 回答1: The WMI class Win32_DiskPartition is what I need. Now to figure out how to use WMI to get this information from a drive letter. Win32_LogicalDisk is also useful, MSDN Example, and this stackoverflow answer. Update: Hmm, this doesn't work! Not in the Windows Installer anyway (WMI is missing from Windows PE!!) so I am using the other answer QueryDosDevice (e.g. \\.\PhysicalDisk1

问题 How could the drive letter (e.g. F:\) be obtained from a known full name (if it is present) of a drive (e.g. WORKMEMORYSTICK) using C# under Windows? Even the other way around would be a start. 回答1: The DriveInfo class exposes a method to get all available drives (GetDrives), you could enyumerate these an match your given string. Something like the following ought to help get you there: DirectoryInfo root; var drives = DriveInfo.GetDrives(); foreach (var drive in drives) { if (drive

问题 Is there a Windows API function to extract the drive letter from a Windows path such as U:\path\to\file.txt \\?\U:\path\to\file.txt while correctly sorting out relative\path\to\file.txt:alternate-stream etc? 回答1: PathGetDriveNumber returns 0 through 25 (corresponding to 'A' through 'Z') if the path has a drive letter, or -1 otherwise. 回答2: Here is code that combines the accepted answer (thanks!) with PathBuildRoot to round out the solution #include <Shlwapi.h> // PathGetDriveNumber,

问题 I've actually got an Windows/Java Question. I've got a plugged-in device which I want to access via Java. Normally you can access an e.g. USB-Stick via the Drive letter... but this tablet is displayed by Windows as a "Portable Device"... which means, that the Path is something like "Computer\Archos 5S" and there is no Drive letter. I want to access a file on this device via Java, but I am not able to figure out the correct path to it. There is a similar question out there, but without a

问题 The program I'm working on needs to access removable drives. Normally this wouldn't be a problem, because the mountpoint should stay the same (e.g.: On Ubuntu my phone's SD card gets mounted at /media/sebastian/GT-S5830/ ) But on Windows there are the drive letters, which can vary. (Same phone: Once E:\ , after plugging in while camera was mounted at E: , it became F: and stayed.) So I want to solve this by not saving the drive letter, but the partition name. E.g.: When setting up, the path E

问题 I am trying to access some files in a device (having "windows CE" application in it) that appears as portable device in windows 7 using java applet.... My device path is like "Computer\Attari's Device\myfile.txt" Now i am trying to access file from it using the same address but it gives path error or file not found. Similarly i used "\\.\Attari's Device\myfile.txt" but it resulted in same error tell me how to access portable devices using java applet When i navigate to connected device and

问题 I wonder if there is a universal way of resolving a path using a drive letter (such as X:\foo\bar.txt ) into its equivalent UNC path, which might be one of the following: X:\foo\bar.txt if X: is a real drive (i.e. hard disk, USB stick, etc.) \\server\share\foo\bar.txt if X: is a network drive mounted on \\server\share C:\xyz\foo\bar.txt if X: is the result of a SUBST command mapping X: to C:\xyz I know that there are partial solutions which will: Resolve a network drive (see for instance
