Windows 10: Network drive suddenly slow to access/index

I have an external drive NAT, but not using that feature with a mapped drive letter on my Win10 computer. Both are directly connected to our home router by ethernet cable. I have not changed anything that I know of, but as of a few weeks ago, getting directory listings or accessing files has become noticeably slower. The disk is pretty full 3TB used of 3.62TB total - it's actually a pair of 4TB disks running RAID 1, but I don't think it became suddenly more full than before - we have just gradually been filling it up over the years. I could spend some time cleaning up redundant or unneeded

Excel 2016 and O365 Excel file contents do not index when saving to a network drive

Hello Jon Hof,

Thank you for writing to Microsoft Community Forums.

I would suggest you in Rebuilding Windows 10 Indexing Options by following the steps mentioned below:

• Open Indexing Options from
  Control panel.
  
• Click on Modify and put a check mark on the required network drive and press
  OK.
  
• Click on Advanced, select
  File types and select Index Properties and File contents. Click on
  OK.
  

Hope it helps.

Indexing Network Drives is not working / Trying to Add Network Drive to Indexing option is not there

Hello,

I am running into an issue with a few of our windows 10 computers. When they are trying to search a network drive, the search take a very long time (some times does not even search) to search and even if it does search, it is not getting everything I need.
I can be in the directory of where the file is and search for it and it will take 10-15 minutes before it shows me the result. It will take twice as long if I enable content searching (which I understand takes longer but 20-30 minutes it a very long time).

• I have tried reindexing. This however only does the C drive and not the network drives. When I want to add the network drives, I am not getting an option to add them. I am not even able to select the computer in Network.
• I have tried running a system file repair in cmd. Comes back with no issues.
• I have tried running a system health restore in cmd. Everything is okay there.
• I have reset the WinCatalog through cmd. Still having issues.
• I right clicked on the network drive and made sure that "Allow this drive to be index" was check. I even unchecked it and recheck it so it will apply to everything.
• I right clicked on the network drive and check "Allow Available Offline" and let that go through its process.
• I stopped the Windows Search service, started it, made sure that it was set to auto and even restarted it. Still having the issue

I have tried these steps at least twice now and after each step, I would reboot the computer.

Is there anything else that I can do to get the search in network drive function to work properly again. Or is there a way that I can add the network drives to the indexing. I have tried third party programs that will search for files but the main thing
we need is the content search. I know content search takes awhile to run but on windows 7 computers, it only takes like 3 minutes to search and find the file with the content in it.
