Hello,

I'm not sure if this is right place to ask for this subject.
However I know there is many computer experts here.
So I hope to hear some good solution.



I run a small business, and we had 5 computers including my laptop in our company.
Some are PC and some are Mac.
To manage files(80% pictures, 15% videos, and 5% documents), I installed Synology NAS, DS218+ with Btrfs formatted seagate 8TH Ironwolf NAS SATA 6Gb/s about 4 years ago.
It was my first time to use NAS, so I didn't know well how to use NAS correctly.
Still I'm not sure what caused the issue. However at that time, about 3 years ago, I found there were many conflicted and duplicated files here and there. And it was not easy to figure out which is the latest version of files because sometime for some reason, files didn't update to NAS even after we edit the files.
So files on NAS sometime were not the latest one.

It was nightmare, and I was the only one who knew about computer in my company.
However, at that time, I was so busy, so I didn't have time to fix the issue.
Now, I have time.
So I'm going to organize files, and will set up NAS again.

Can you help me to figure out
  1. The best way(or app) to delete duplicated files easily
    I have 400GB duplicated files here and there.
  2. The best practice to use NAS preventing conflict and duplicated files, etc


By the way, I want to add little more detail what happened at that time.
The basic concept that I had in my mind was like below:
If I install Synology Drive on our 5 computers, and setup "Two way sync" for all computers, and If we add/edit/delete files and folders in Synology NAS drive in one of computers, let say computer A, then computer A will update files on NAS server, and the rest computers will fetch all updated data from the server.
However, sometime, I found that after updating files in NAS drive in computer A, and if we turn on computer B, B updated files on NAS server , and A and rest computers got data from B. This is just one example what caused the mess.
There should be more.

Thank you.
