Windows 10: 2 identical Files installed and 2 differents content....

First of all, I am french so, sorry for mistakes,


I just bought i new laptop with windows 10 and I had a problem with my different windows users .So I just finished erasing everything and now its a new one! So here is my problem. It seems that i dont see all files when i install softwares. I just installed EZdrummer and i can find the file where i intalled it but no .exe in it.


So i tried something. Installing same file in 2 different location and booooooooom . 3 files is missing....


I try to install a softwhere in the D/ location but my software dont ask me where to install it so its stucked in there, everything is there but no .exe again.




Can someone Help me plz

@Ford
I don't think that step #3 is even needed. The probabiliy of two MD5 hashes from differing files colliding is what, 2^-128 ?
Even if your were hashing a million files the odds of a hash collision on differing files is astronomically small.

 

How can I compare 2 file folders in Explorer to see if they are identical with information?

I am trying to compare 2 file folders on my laptop and USB drive. I want to open them at the same time and do some sort of file compare to make sure they are identical. Can anyone suggest the steps to do this? Thank you!

Neat idea but...I would recommend doing a 1:1 compare...

1. If filesize is equal, move on to step two; else, not identical.
2. Read one chunk (4096 bytes) from file A and file B into separate buffers.
3. Use a for loop to make sure all bytes are equal: fileAbuffer == fileBbuffer
4. If an inequality is ever discovered, break the loop, close the file streams, and output non-match. If they are equal, rince and repeat until End of File is reached.

Using this method, you could even have a percentage match option where you count the differences and use the filesize as the denominator in creating the percent. If not above a user specified percentage (100% if not given), reject it.


The method described above would likely be faster than md5.ComputeHash(file) on large files because it could stop on the first byte.
