First of all: can you create such a folder?
First of all, make sure you can create a folder with the desired name.
Try it upfront: right-click the parent folder, then click New, then click Folder, then type in the desired name, and then press Enter
.
Had success? Ok, delete (or not) the created folder.
Could you not create the folder? Try running CHKDSK
or, if it didn't work, look for any clues at the eventvwr.msc
Ok, a folder with the desired name can be created
You may try changing the default location of 'My Documents'.
Following (more or less) the instructions from Microsoft (at http://goo.gl/EWvhh0).
- right-click the current 'Documents' folder (the one you want to rename)
- click Properties, and then click the Location tab
- change the path in the text box to the desired one, and then click Apply
Windows will then:
4.1. try to create the new folder (if it does not exist)
4.2. move the files from the original folder to the new one
4.3. and assume the new folder as THE 'My Documents' folder
If Windows fails at step '4.1', well, man, it's past the time for a clean setup.
(Anyways, this question is so old that I doubt @JustinasDūdėnas still needs it to be answered, that he still is using the troubled Windows 7 setup...)
