File Explorer in Windows is like a doorway to the files lying on your hard drive. Also called Windows Explorer or This PC, you can use this application to access or organize the different types of files and programs present on your computer.
It’s an essential app which is natively present in Windows operating systems. So, a malfunction of this app such as, it refusing to open, not responding or crashing frequently can make your computer almost unusable.
There can be numerous reasons for File Explorer not working as expected. Here, we have listed some of the most common reasons and ways to fix or rectify them.
Disconnect Any External USB Storage Device
External storage devices like SD Cards, Card Readers, External Hard Drives or USB sticks can sometimes cause File Explorer (Not Responding) issue. This happens when File explorer is unable to read data from the external drive, due to corruption of files, faulty cables or when Windows is running low on memory.
Try closing apps like Web Browsers to free up some memory. Complete any file transfers before you try to access any files on the external drive. Also, disable the thumbnail view for files if you are trying to access a folder with a large number of files, especially on an external drive.
