Failing file copy procedure

[Reinhard125]

This post is not about a TC bug, but about a failing file copy attempt caused by Windows, where TC could be of help to handle it.

I often copy file from a mapped network drive (with an own drive letter) to a windows program directory, e.g. c:\Program Files (x86)\myProgram\.

When doing so, I am asked to grand administrator privileges to write to the program directory, which I do. However, the file copy fails, because after granting administrator privileges I no longer can access my network drive.

The reason is, that elevating the privileges does not change the privileges of my normal user account, but actually Windows has a second account in the background, which has the administrator privileges. Windows switches to this second account, when needed. You can easily verify this, by starting TC with administrator priviliges and then look for your mapped network drives. They are gone!

Proposed solution using an intermediate local directory:
If such a situation is identified, first the files should be copied from the network drive to a local drive, then administrator privileges should be granted and then the files should be copied to the destination directory.

Ceers,
Reinhard

First its not a bug so it belongs to suggestions forum.
You are kidding with your proposed solution.

No, it would be much better if TC would resolve the network mapping to UNC (there's an API function for that) and TC's admin tool would try to copy the file from the UNC path instead.

Are you sure that the elevated account would have read rights to the UNC path?

No, I'm not sure that it works in all cases. However, directories/drives are shared for users/groups, not users/groups with specific privileges/rights. The only case I can think of where my suggestion wouldn't work is when a network share can be accessed by users only, but not by administrators. (I don't know if elevated processes access network shares as administrators.)
