This could be frustrating when you are struggling to free up some space and a few troublesome files stop you from proceeding. Some frequent errors that appear in Windows when trying to delete undeletable or locked files are:
In few cases, the file can’t be removed or deleted as it is being used by another application or essential program.
This can be caused by a virus, malware, spyware, adware, Trojan horse, or corrupt/damaged system files and permissions that locks the files, thereby making them undeletable.
