TextAloudmaisVozesSerialKey I use Windows 10, and while I don't use a CD drive, I have a USB 3.0 external drive I'd like to backup to and it's set to backup to the external drive. In Windows Disk Management, I right-click the drive, and choose the option to "Safely Remove Device". I then attempt to drop the files to the external USB drive. When it's all finished, I go to the drive again, and see that "Virtual Disk" is using about 25% of the available disk space. In "My Computer", I still see the backup files, but the disk space is back to the free space shown in Windows Disk Management. Rebooting the computer and checking with Disk Management again (as many times as I can remember to check), the "Virtual Disk" is listed, and is occupying about 17% of the available disk space. For comparison, I have a hard drive that's been in the computer for years, and it's hard drive capacity is listed as ~120 GB (148 GB used, ~36 GB available). I have a couple of other USB drives in the computer, and they are also "Virtual Disk" even though they are empty. I don't have any external hard drive, and while I'm not sure if it's the only thing in the computer, I'm not sure how I'd create a backup if I had one, even with an external USB drive. Questions: Why is "Virtual Disk" showing that the backup is taking up so much space, and is it a normal process? How would I delete the backup and make sure it doesn't come back? A: A Virtual disk is a virtual representation of the whole disk on the internal drive. If you unplug it, no data is deleted from the internal drive. If you are backing up a external USB drive, it is possible that the backup file is taking up more than the available disk space due to the limits of the USB drive. Your computer may have less than 20 GB of available disk space due to the USB, but the disk is potentially larger than that, and the backup files could take up a lot more than a 20 GB USB drive can hold. As an example, how much data would a 5 TB drive hold? An equivalent 1 TB USB drive? That's a lot of storage. USB drives are not inherently larger than internal drives, but they have much more limited storage capacity. If 2009 SP4 Retail.. 2008 SP5 Full Retail..

I have a simple class like this class CVector2 { public: double x, y; int id; CVector2(double x_, double y_, int id_) : x(x_), y(y_), id(id_) { } }; In the main function I do this: CVector2 c1(4.5,3.9,1); Then in the program I do this: c1.x++; c1.y++; Then I do a check: if ( c1.y > 5.5) cout 648931e174
