Delete Recycle bin

Sometimes sending a file to the Recycle Bin can be considered a computer action, leading to an error that we are trying to solve. Another way to solve the problem is to go to the Recycle bin and empty the entire folder by selecting the files and deleting them. It should be warned that this will permanently delete all files in the recycle bin, so make sure to select only those that you are sure you will no longer need.

Check the directory to find viruses

Finally, if none of the above methods worked, the problem could be more serious. There may be file-related viruses that prevent you from making changes. Run the file via antivirus software to find any viruses or malware that may appear.

If that's the case, isolate the file with anti-virus software and delete it before it infects other files.

The 'File Is Open in Another Program' error can be an annoying problem. Fortunately, there are several ways to solve the problem as mentioned in the previous sections. If the cause of the problem is caused by a virus, it's best to be aware of the fact that there is a virus in your computer to take steps to remove malware from the device in a timely manner.

Hope you are succesful.
