// The default temporary folder location for use in the windows algorithm.

|
|
// It's TEMPting to use dirname(path), since that's guaranteed to be on the
|
||
|
|
// same device. However, this means that:
|
||
|
|
// rimraf(path).then(() => rimraf(dirname(path)))
|
||
|
|
// will often fail with EBUSY, because the parent dir contains
|
||
|
|
// marked-for-deletion directory entries (which do not show up in readdir).
|
||
|
|
// The approach here is to use os.tmpdir() if it's on the same drive letter,
|
||
|
|
// or resolve(path, '\\temp') if it exists, or the root of the drive if not.
|
||
|
|
// On Posix (not that you'd be likely to use the windows algorithm there),
|
||
|
|
// it uses os.tmpdir() always.
