16557	Case sensitive path names under Windows 7	Hans42		"Hi,
I have an issue after I upgraded my vbox to 5.1.16.
The host is running Umbuntu 16.04 64 bit
The guest is running Windows 7 Professional 64 bit
The configuration was running fine until I updated to 5.1.16

The configuration uses a shared folder /data on the linux host to provide storage to the windows 7 guest under drive L:. The content can be accessed from the linux host and the Windows guest.
Since the upgrade to 5.1.16 the files on L: (Windows machine) became case sensitive. Usually file names under Windows are case insensitive so test.txt and TEXT.TXT are the same file. But suddenly they are different. If a program write test.txt and later wants to open TEST.TXT then the file will not be found if is located on a shared folder. On a ""normal"" virtual storage (C:) everything works as expected.

A side effect of the problem is that it is not possible to rename a file on a shared folder if only the case of the characters are changed.

Since many tools under Windows rely on the case insensitivity of the system, it is critical bug.
