Or by shortPathName() in R.
But that does not help if R itself is generating the name (here I
guess .Library). R on Windows used almost always to generate 8.3 (aka
DOS) names, but since useRs are nowadays confused by them it
increasingly quotes canonical names.
Spaces in names are not unique to Windows: they are also common on Mac
OS X (which has no concept of 8.3 names). The problem (as the rw-FAQ
points out) is poorly written packages that fail to use quotes in
shell command lines (including those generated from makefiles).
