How on earth do you compare THE SAME files in THE SAME folder when they're in different drives?
----
I have a C-Drive (Windows 10) and several EHD's (external hard drives).

The EHD's mirror what is on the C-Drive, I use the EHD's to back up the exact data, the exact number of files, that are found on the C-Drive.

Problem: Sometimes my C-Drive might have a folder that has way more files in it than the EHD does. For example, the My Pictures folder located on the C-Drive

might have 1,100 files in it

and the same folder (My Pictures) located on the external hard drive might have less,

950 files in it, for example.

Is there a procedure (or a software program) that will

quickly find, highlight, and point out

the 100 outstanding files so a person can transfer them over to the EHD?

My EHD's are remotely stored in a safe deposit bank at a chosen bank. I swap them out, or rotate them, about once a week.

If you're a code king or code queen then please dumb your answer down (way down) because I'm a simple person who mows lawns for a living, thank you :)

Hi IceHockeyPrincess :)

You can use WinMerge for issues like these, it works wonder. I used it in the past to compare the folders and files I moved from my C: drive to a USB Flash Drive (since some of them couldn't be moved) and it identified the missing files.

It doesn't look like Just Manager compare any folders or files Tom. It's more of a "multi-windowed" Windows Explorer.

Update, before I say thanks.

I lucked out big-time: I found some software that will compare a folder that might have a million files in it, when said folder is kept safe on multiple EHD's and uniformity is critically important.

The software has turned out to be a lifesaver and a time saver too because a missing file in a folder that has thousands of files

used to take 30 minutes or a lot longer

to identify

but now takes about one minute of time to identify the missing file(s).

Also, besides cutting down the time it takes to hunt down a file(s), after acquiring the software I learned that precision is no longer important, I can be sloppy and not worry about uniformity when creating new files and then storing them on separate EHD's -

like the night before I go to the bank and I need to be 1000% sure that both drives are uniform because I'm going to put the drives in a safe deposit box.

As soon as I downloaded the software this layperson saw some things and I was immediately hit with a good feeling by what I saw:

1) When you open the program you see 5 icons and one icon is labeled 'Folder Compare' (eureka !!! ... those two words spoke volumes)
2) Click on Folder Compare and then a window opens. Said window is split in half. At this point I was still trying to figure it out when up near the menu bar I saw a lot of icons but the one titled 'Diff' stood out like a sore thumb and I asked myself
3) Does 'Diff' mean it will compare the same folder that is stored on different drives? - boy, lets hope so. I soon learned that, yes, it is indeed the icon that compares folders and that is why
4) The window is split in half, because you drag and drop one folder, from each separate EHD, and into each half of the screen in order to compare the contents
5) You then click on 'Diff' and the program then HIGHLIGHTS the files that are missing :)
6) All of the above takes about one minute

After stumbling on the software I went to bed that night feeling as if I had finally eliminated a huge problem from my life. The next morning I was of course interested in the price, because I had downloaded a free 30 day trial - I learned that it costs $50, pricey which is what I was kind of expecting.

Over priced? Oh heck yes, but

since it can potentially save me a ton of time,

because I go to the bank on regular basis to swap drives,

and because you can't and never should put COMPLETE trust into online storage companies like Jungle Disk to protect your data,

the over priced $oftware is worth it to me.

Several years ago Jungle Disk lost ALL of my data when they made changes to their sites interface. The change to their sites interface,

coupled

with the loss of every single digital file I had, may, or may not, have been a coincidence. I will never surrender COMPLETE trust to any online storage service.

Sorry, but I can't, and will not, give out the name of the comparison software because you probably know why.

I came back to say thanks for taking the time to answer my important call for help that I lobbed towards the community

and to wish everyone Happy Labor Day 2015 :)
