问题 I have what seems to me an odd situation: an old .exe of the project on which I'm working runs on a handheld device. New versions don't (even the exact same code with no additions). Even that .exe that runs on one handheld device doesn't on the other. See this for some of the gory details. Based on this, I thought I could track down the problem. But this PC util tells me what is missing from that (PC/build machine) environment. I need to know what is missing/wrong on the CE device. So to

问题 I need to determine how much free space there is on a Windows CE device, to conditionally determine whether a particular operation should proceed. I thought Ken Blanco's answer here (which bears a striking similarity to the example yonder) would work, which I adapted as: internal static bool EnoughStorageSpace(long spaceNeeded) { DriveInfo[] allDrives = DriveInfo.GetDrives(); long freeSpace = 0; foreach (DriveInfo di in allDrives) { if (di.IsReady) { freeSpace = di.AvailableFreeSpace; } }
