Files with both hidden and temporary attributes on belong to LabView 
2015. I found 2 in "C:\ProgramData\National Instruments\NI-DAQmx"
{509E1DB5-B477-49b8-AF59-114DC801074C}RrWr.lock
{509E1DB5-B477-49b8-AF59-114DC801074C}Write.lock
and 3 in
"C:\ProgramData\National Instruments\Shared 
Memory\platform\memory\sharedMemoryFiles"
48d09ae7-0894-4c28-ab25-b6f1cdea221f
pimmInternalFloatingSharedHeap
pimmPublicFloatingSharedHeap.

With the snapshot 2018-03-09 all mentioned files are visible by "ls" and 
"rm -r" removes directories with them (I do it offline after reboot to 
Windows PE).

Thank you.
