Sometimes, from both copying and pasting to our hard drive, we end up having repeated information, and this redundancy only serves to unnecessarily take up space on the hard drive. In these cases you need a tool like Vallen FileComp.
Vallen FileComp allows you to compare two different folders with each other, comparing file by file to see if they are exactly the same. The process is recursive, so if the folder had subfolders it will also be compared with the corresponding subfolders, and thus verify 100% if the other folder contains exactly the same as the original.
Vallen FileComp is also interesting to confirm your backups, and thus verify that the content of the original is the same as the copy made.
You can free download Vallen FileComp R2 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
