Running a process in a virtual file system?

[Qub1]

Hello,

Does Qt provide any functions to start a process inside a virtual file system? What I mean by this is that the program thinks some folder and files exist in its own directory, while actually they are somewhere else on the drive.

So for example, this would be the actual structure:

• My program's directory
  --- folderA
  ----- fileA.txt

• Other program's directory
  --- folderB
  ----- fileB.txt
  --- folderC

And this is what the other program would think the file structure is:

• My program's directory
  --- folderA
  ----- fileA.txt

• Other program's directory
  --- folderA
  ----- fileA.txt
  --- folderB
  ----- fileB.txt
  --- folderC

So would there be any way to achieve this with Qt? And if not, could you suggest some other libraries or just plain C++ code to achieve this?

Thanks in advance!
