Getting error code 0x800701E3 when copying files from laptop to external hard disk

I had not seen your last post [starting I need to take a step back here I have trying to do too many things,issues ...].  I was writing my post at the time.

There is a folder C:\Users*YourUserName*\AppData and it does have the subfolders you mention [Local, LocalLow, Roaming].  That is the correct place for it.  It was never at C:\AppData or anywhere else.  AppData is a hidden folder so you may not always see it [you can set File explorer to show hidden folders & files].

SFC will not address this issue.  It only checks the integrity of a set of Windows system files.  No more than that.

What do you mean, "The file structure and layout had been wrong for awhile"?

The only way to restore file structures to what they ought to be is to run a "Repair install" procedure or to do a clean [complete] reinstallation of Windows & all your applications.  A Repair install is when you run the installation USB/DVD within Windows [instead of by booting from it, which would reinstall Windows instead].  A reinstallation would require you to back up all your own files first as everything on the disk would get overwritten. 

What was the issue that made you "restore"?  And what exactly do you mean by "restore" as there are several things that might be called that.  Do you mean you ran a "System restore" at System, System protection, System restore?  If so, that is also a very limited measure and it will have no effect on folder structures.

If you have managed to move folders then Windows cannot think they were critical ones or it would not have allowed you to do it.

Defrag does not restructure any folders either.  It does not help with such a problem.

Perhaps a complete reinstallation is the best way forward.

Step back with me I don't care about the issue of the xhdd right now so which r u addressing above ?? Right now is to get the file structure back so is the defrag reply addressing tht issue ??,  familiar with that but how is that going to put a file back to where it belongs ?? My understanding of it is that it would not only a space allocation tool.

This is in reply to your  the post above yours....

If defrag was the answer to this defrag auto on and shows all drives 0 % fragmented, would not run already optimized..So the file structure back to the way it was retore ?/ Did nt work before ..

I don't really have anything to add to ZigZag's article on SFC.  I do not now anything about DISM as I have never used it.  Several people say that SFC sometimes only finds problems on the third run but I have no experience of this [I have never known SFC find anything, so I suppose I am lucky].

I cannot see it being a driver issue but it is easy to check.  Open Device manager on both computers & look at the driver version for the external drive.  To do this, right-click on the entry under Disk drives for the xHDD & select Properties then the Driver tab.  If they are both the same then this is not the cause.

What antimalware applications have ever been run on the laptop?  If you have removed any in the past then they can leave behind residues that cause all kinds of weird symptoms.  I removed Norton at the start of 2010 & at the end of 2011 I had a problem copying large files on my internal network.  I then did what I had discovered I should have done in the first place and run a special removal utility for Norton and the problem was solved.  So if you have ever uninstalled any antimalware applications, including any trial versions that might have come with your computer, go to the maker's website & get their own removal tool [if you search for their guidance on removing their software, they'll either give you a link to their tool or tell you that it is not needed in their case].  MSSE does not count, it leaves behind no residues so needs no special removal tool.

One final shot in the dark.  Run defrag on your hard drives - use the Defragmenter interface for it.  You can get to it in one of these ways:-

1  Type defragmenter into that deranged search engine Cortana

2  Find it in Start menu, All apps, Windows administrative tools, Defrag & optimise

3  Go straight to it in File explorer at %windir%\system32\dfrgui.exe [and make a shortcut to it for future use] 

{%windir% is a variable that means C:\Windows for most cases but it can cope with your drive or Windows folder being called something else yet still find the right place}

Defrag can take a long time to run for the first time so perhaps you could run it when you are doing something else for a while.

I am only suggesting this because I have seen some very odd things solved this way and it is something that you will want to do at some stage anyway so it is not a waste of time.  You can run it on both your internal & your external hard drives. 

If nothing else fixes the problem then you are going to start wondering about doing a fresh installation of Windows 10.  Your installation USB/DVD can do that but you will also have to backup all your own files and reinstall all your applications.  It really is a lot of work.

I need to take a step back here I have trying to do too many things,issues  at once and getting into too many issues for both pcs at a time...and screwing up was in the c drive and dragged a file into a folder should not have !! I Lost what the file was from c to where don't know ?? The file structure and layout had been wrong for awhile and I need to get back where was at appears that the SFC/scan now may do that ?? Ran a restore (for another issue) and it did not restore the original file structure as was before..so what can do to get it back..to where it should have been >>

The original file issue was there are files and folders that are laid out under the pcs name they are not there, the original ones are under a file in the userers folder but only can access if open c and go directly to them, now make it worse as I said dragged a file from c to know where ? It could be a system file for all I know..So just need to get all this back to the way it was appears that sfc/scannow may do that ?? or what ?? Going to wait to hear for you before I reboot, Don't want it to save settings.

I looking a little further after I wrote this I believe that I moved the folder App data which was the first folder under the c: directory which is now in a users folder, went to check the desktop but under c there is not a App Date folder listed there,,In the folder is a 3 file folders listed as file folders called roaming,local roaming and local....would not believe that this would be in a users folder so sure this is the ine that I moved ??????
