I started using NERDtree plugin on a a windows platform. I can't seem to find a way to change the drive letter. Going up all the way on the directory tree doesn't lead to the drive letter. Any ideas? (Yes, I know, it's going to be a simple answer)
If you want to go to your Z drive, for example, start it as:
:NERDTree Z:\
If you use:
:NERDTree d:\
in the NERDTree window you will see it works. But now if you open(and edit) a file with NERDTree you will find it can not be saved, because the current working directory has not changed'; it is still in the old directory!
So if you want change the drive in NERDTree I advise you to perform the following 2 steps:
cd drive:\
:NERDTree .
where drive is the drive letter you want to change to, and . means change the NERDTree directory to the current working directory.
Now you can use NERDTree opening (or editing)the file in new directory now.
