is there any software to comparing files???

Tsw88 · 15 Aug 2017

For example, I have a couple of hard drives that are storing tens of thousands of files. There might be some files that are identical. Is there any software that can check all files in the drive to see if there are any files that are identical ? The software should not check only their filename but also the content of the files. The same filename does not necessarily mean the identical file.

Works on Windows 10 too. The interface might be confusing at first but it does what you are asking for.

CCleaner has one under tools. I have not used the Content filter yet.

It works, but I'm not sure it would be suitable for the task that the OP is facing; i.e. comparing "tens of thousands of files".

AFAIK it has significant limitations:

The exact folder locations of the files to be compared must be explicitly entered
It can only compare the contents of a maximum of two folders at a time.
The files to be compared must have the same exact name, otherwise misnamed duplicates can be missed.
There is no built-in function that automates (preferably by a GUI) a summary display of duplicate files and a means to deal with them (i.e. choose which duplicates to move, delete, etc).

Doublekiller, which I referred to above, is a simple, elegant GUI program which addresses every one of these deficiencies.
