multiple folders of cached GPU kernels under Ubuntu/Mint - are they all required?I

Software darktable

I notice there are multiple folders containing GPU kernels in ~./cache/darktable, with the name of the form ‘cached_kernels_for_NVIDIAGeForceGTX1050_5258505’. They’re quite small, but are they all necessary? If not, how do I safely remove the old ones?

Cached kernels are updated every time your Nvidia driver has been updated. Only the latest is necessary. Folders you don’t need can be removed. If you accidentally delete your recent folder dt will create a new one at next start.

Now I understand. Thanks.
