Can't move "My Documents"!!!

Well, everything is in place!

I deleted the old account, and I changed the location of the documents folder as I wanted to. Same procedure as mentioned at the beginning of the post, but setting a folder "My Docs" as the destination on partition D. As a result, the "My Docs" folder has been replaced by the "My Documents" one. It's perfect.

Thanks to everyone. I'm closing the topic.

Hello,
by default Windows 7 only shows one restore point.
Look further down, there is a checkbox "show other restore points"; there should be other dates available.

Hello CMP,

Well, no, even though I check "Show more restore points" and click "Next," it doesn't offer me an earlier date. It goes straight to a confirmation request for restoration on the only restore point date.

But I have had a small flag in the taskbar, in the bottom right, for a long time now, saying that I need to "check backup settings": "Windows cannot find the disk or network location where your backups are stored." It offers me to either "change backup settings" or "try to run the backup again."

I don't know what to do...
Thank you for your help!

No one sees how to help me? !!!

Please, help!

Hello,

You just need to redo the shortcut link modification from "documents" to a specific folder..

By going through "computer", create a folder on D called "mydocs" (or something else). Then, on the desktop, right-click on documents, properties --> Location --> Move --> Drive (D :) --> Select a folder --> mydocs. Confirm.

In principle, the "documents" icon should now point to the specified folder. You just need to move the files inside.

Well, I'm trying to present everything to you by separating the text from the images. I hope it stays clear with all the screenshots I've taken...

By going to Computer -> Local Disk (C:) -> Users, I get this. The weird thing is that I don't have the folder with my name ("Laurent"). I will show you all the windows chronologically (I have three hard drives, one of which has two partitions, C and D):

(Images 1, 2, 3)

In "Default" there are empty folders (or almost), the same in "LogMeIn...", and concerning "Doc for Blandine" I don't know why it's there! It should be in a sub-subfolder of "My Documents," but never mind.
First of all, if you could help me understand how the structure of Windows 7 is built. I would have thought that the "Laurent" folder (that's me!) would be in "Users." But no, I have to click on "Desktop" on the left in Windows Explorer to find it:

(Image 4)

When I open it, I see this:

(Image 5)

And I find "Desktop" again. In fact, I imagine that this is the real folder, whereas in the left column of the explorer, it's a shortcut to this folder. If I open "Desktop," I have:

(Images 6)

It's a bit different from the first Desktop. In fact, in the first desktop, in addition to what I myself have put, there are items (or folders?) that belong to Windows: Libraries, Laurent, Computer, Network, Control Panel, and Recycle Bin. Out of these elements, only the recycle bin is actually on my desktop (you can see it in the first image).
Well, I don't know if all of this is normal, and it's hard to understand the structure. The "Desktop" folder seems to have a multiple identity, and the "Laurent" folder is not in "Users." (By the way, sometimes it's labeled "Users"...)
But the purpose of my quest here is to find the "My Documents" folder. So I click on "Documents" in the left column of Windows Explorer, and I indeed see all my documents appear:

(Image 7)

If I click on "Partition (D:)", I get the same thing:

(Image 8)

But if I click on "Public Documents," I get an empty folder (no need to show you that!).
By the way, I remind you that I have "Partition (D:)" instead of "My Documents" in the left column because I wanted to move the "My Documents" folder to partition (D:), as I explained above.
It’s impossible to move this "Partition (D:)" back to put "My Documents" in its original place. You can't move a partition! Here’s what I get when I try:

(Image 9)

I click on "Move" and I get a window that allows me to choose the folder where I want it to be. I click "OK" then I return to this window, where I click "Apply":

(Image 10)

Then I get the warning window asking if I want all files to migrate, I click "yes."
Then I get this error window:

(Image 11)

I tried other ways, through the Properties menu on "Documents" in the left column of Windows Explorer, I get this, which is not usable:

(Image 12)

And in the properties menu on the Documents shortcut found on my desktop, I get this, also unusable:

(Image 13)

Phew! And now, I will try to upload the images in question!!!
Well, I don't understand anything about English (on ImageShack) but I think the right link to view the images is this one:
https://imageshack.com/

I'm now trying to distribute the images across several links, but it's impossible because apparently, I can only use my email address once with ImageShack. I don't understand their system. It’s not going as indicated in the CCM tutorial. So we have to settle for this link where all the images are grouped together... What a hassle!

you just have to click on:
"default value"

everything I just read is so complicated ...

it's true, why make it simple when we can make it complicated?

the chair / keyboard interface is the hardest to set up.

Thank you all! I'm disheartened to see you arguing while you want to help...

I had to let these 8 days pass to finish a building permit file before taking any risks messing with my computer.

Rafi, what you propose doesn't work in my setup. The "default value" button you mentioned corresponds, I imagine, to the "restore default values" option in the Document Properties window, which we see in the second to last image I posted (check the long post from August 19)? Well, it doesn't do anything. I click on it... nothing!

Ikewdu, I see that I misinterpreted the solution you proposed. It indeed seems to be the simplest one. So I'm going to try it right away!

Thanks again, everyone.

PS: by opening the window to manage user accounts, I noticed that there is an account whose existence I was unaware of. It is titled: ASP.NET Machine Account. And it says in small print "Standard User" and "Password Protected".
Is it not the one that caused the mess in my system?
