strange behaviour when shift delete in windows explorer
Solution 1:
Assuming you are on windows - right click recycle bin and check if:
- "don't move files to recycle bin" is checked
- "display delete confirmation dialog" is not checked
These two selections together make the confirmation dialogue on shift-delete to no longer appear
Check and set the options as desired for each drive present in the recycle bin since it has separate settings for each drive/partition.
PS: the scandisk suggestion is not useful and won't find the cause since it's caused by this specific setting and not a system file error.
