Q:
Alcohol 120%可以虛擬31台光碟，但是windows只能管理26台ide設備，出去A:\B:\C外，還有23個磁碟代號可用，那麼其他沒有分配磁碟代號的虛擬光碟如何管理和使用呢？

解決方法，供和同樣疑慮的朋友參考：

if you are running windows versions upto 2000 and you do not have enough free drive letters none will be assigned after Z but the drives will still be created.

However If you are running Windows 2000 or XP Pro you can once you run out of drive letters mount a volume (CD, Virtual CD or hard drive) as directory

Say you want to have a virtual CD drive with Microsoft Office 2000 mounted permanent

you could create a directory (folder) on your hard drive call say "OfficeD1"

Then go to Control Panel - Administrative Tool - Computer Management - Disk Management

Then Select drive you what to mount right click on it, then select Change Drive Letter or Path.

and select the OfficeD1 folder you created..

This only works for a directory on ntfs volume, and the directory must be empty.
