When I have Boxcryptor running in the background it adds a new 32kb file in the format "tmpXXXX.tmp-shm" every approx 13 secs. For example:
"C:\Users\ezdmanx\AppData\Local\Temp\tmp1B00.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmpDFEA.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmpA4F3.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmp69ED.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmp2EF6.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmpF3F0.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmpB8F9.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmp7E02.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmp42FC.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmpCBF4.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmp90FD.tmp-shm"
"C:\Users\ezdmanx\AppData\Local\Temp\tmp55F7.tmp-shm"
When I kill Boxcrytor the file creation stops. The Pid creating the files points to "System". I clear out GB's of these files every few days.
