I recently faced a technical issue while doing development in windows environment.

I tried to import shipping method rates & table rates in Magento 2.

That action threw me an error which said,

“The file “C:/Windows/Temp/E:/wamp/tmp/php9B36.tmp” doesn’t exist”

I audit my code again and found everything was correct. But then I realized, that I was working in windows environment.

The default upload file temp directory set in php.ini by WAMP is accurate location.But, I changed it to this setting.

I found this line:

upload_tmp_dir = "E:/wamp/tmp"

& change it with this characters:

upload_tmp_dir = "C:/Windows/Temp"

Then, I saved the file & restart apache.

After uploading the file, it worked for me. VOILA!
