test\r\n 4 File(s) 1,895 bytes\r\n 7 Dir(s) 133,166,219,264 bytes free"
julia>
```
I am sure I can figure out a way to obtain the free disk space from this. However the Windows command
```julia
julia> a = `fsutil volume diskFree C:`
`fsutil volume diskFree C:`
julia> b = readchomp(a)
"Total free bytes : 133,171,417,088 (124.0 GB)\r\nTotal bytes : 510,208,765,952 (475.2 GB)\r\nTotal quota free bytes : 133,171,417,088 (124.0 GB)"
julia> typeof(b)
SubString{String}
```
gives both the free disk space but also the total disk size. However it needs administrative privileges to execute. In this case I right clicked on Julia to run with administrative privileges. How can I get this to run without running Julia with elevated privileges?
Or is there a better way?

Use `runas`

When I remember correctly it will ask for password and saves it for successive runs if you use `/savecred` until the users password has been changed, then it will ask again. Something like that, you will need to experiment a bit.

I didn’t want the extra bother to try and run with elevated privileges, so did another search and found another command that works. The code is shown:
```julia
"""
function diskspace(drive::Char)
find size of disk and remaining free space
drive is one letter identifier for the windows drive
returns disksize, diskfree
"""
function diskspace(drive::Char)
try
if Sys.iswindows()
# function to find vector element for the appropriate drive
f(x) = for (i, ss) in enumerate(x)
# @show(i, ss)
ss[1:2] == "$(uppercase(drive)):" && return i
end
a = `wmic logicaldisk get size, freespace, caption` # windows shell command to read disk space
b = readchomp(a) # execute command
c = split(b, "\r\r\n") # create vector of drives
i = f(c) # get appropriate element from vector
# @show(a, b, c, i)
d = split(c[i])
global disksize = d[2]
global diskfree = d[3]
else
error("function diskspace is only implmented for windows")
end
catch
error("drive letter $drive not recognized")
end
return disksize, diskfree
end
```
with the results:
```julia
julia> diskspace('c')
("132984524800", "510208765952")
```
