With ramdisk enabled and temp folder on ramdisk it will delete the temp folder

[Arryboom]

#14
#14
above is the issue before,I found the root cause:

on my win10:

Z: disk is a ramdisk
%TEMP%->z:\tmpb
%TMP%->z:\tmpa

after few tests with .\iperf3.exe -c 172.16.211.1 -u -R -b 0 to server(iperf3 -s)

the folder z:\tmpb totally disappears in z:\

cause

PS D:\WGWG> .\iperf3.exe -c 172.16.211.1 -u -R  -b 0
Connecting to host 172.16.211.1, port 5201
Reverse mode, remote host 172.16.211.1 is sending
iperf3: error - unable to create a new stream: No such file or directory

I'm not sure whether it's a bug that deleted the folder after tests,or a ramdisk compatibility issue,the ramdisk I use was AMD Radeon RAMDisk latest

Told you already in #14, its an issue with your temp folder, it will throw that error if temp env variable is not set properly.

iperf3 is not deleting your temp folder. It just reads the env variable and writes a temporary file to that location.
Its an issue with your setup. Simplify your test and and use an actual location on your drive for temp env variable.

I let iperf3 server running for days at times and connect clients hours post-initial tests they work fine. With temp env variables on an actual ssd rather than a virtual memory.
