OBS Studio not enough space to record what to do?

I want to record my laptop screen, but OBS Studio says when I press Record, "There's not enough space to continue recording". What can I do to get it away?

Unfortunately, nothing helps except to empty the memory on the hard disk on which OBS is installed.

Either delete things or buy a larger plate. But if it has to be quick and it is not an eternally long recording, insert a USB stick into the PC and select it as the storage location. Gives you at least 8GB (or whatever size you have)
