There are too many opened files already. Please close some first.

Hello,
When I tried to open a file. I get "There are too many opened files already. Please close some first." error message.
I closed all the files. I tried to open a file. Still same error message.
Please let me know how to fix.

Thanks,
Sumanth.S

Do you use an external editor with "External editor opens each file in separate window (process)" option turned off?
Then the only solution is to restart WinSCP.
If you hit the limit often, you can increase it in registry:
