"Does my Windows computer have a duplicate file detector?"
“I have downloaded hundreds of files from the internet. I have made some copies of them in different folders. Those files are taking up a lot of space and it is really frustrating to search for each of these files and delete them. I found many duplicate file finders searching the web but I don't know which one to trust since some free programmes install malware. I would like to know whether there is an inbuilt duplicate file removed for Windows 10. If there isn't please suggest a good programme for it. Thank you.”
A large number of duplicate files can quickly fill up your storage space and lead to disorganization of your data. However, unfortunately, Windows does not offer a dedicated program for identifying these files.
