Windows 7: Error: "You must type a filename" when renaming folder under roaming .

Win 7 Home Premium 64-bit
Error: "You must type a filename" when renaming folder under roaming .

Running: Win 7 Home Premium 64 bit, service pack 1
Logged in under account with administrator privileges (checked)

I am trying to rename a folder that lives here: C:\Users\Username\AppData\Roaming

When I right click on it and select rename and change the name ".foldername" to ".foldername2" I get the following error from Windows: "You must type a filename"

Not sure what it's trying to tell me... But the "new" folder name ".foldername2" doesn't exist...

Any ideas? I googled but didn't find any info about rules for managing directories that live under the roaming folder...

Thanks in advance!

Hello OldDogEyes,

You are getting that message since you have a period at the start of the name. Only what is in front of the period is consider the actual "file name". Anything after the last period is considered the "file extension" for a file. You'll have to type something like "foldername2" instead without the period.

Hope this helps,

Renaming the "Users" folder
I don't want to rename a user PROFILE, I want to be able to rename the Users folder (i.e. E:\Users) to Users.old and change every single link in the registry that points to it. The reason I want to do this is because when I first installed Win 7 Ultimate I forgot to unplug my old Win 7 Pro HDD &...

Searching: Change Default Search options to set/add "Type:Folder"
We have upgraded our systems to Windows 7 (From XP). I have setup Indexing on our server and the employees use the Search Bar (upper right on a window) to search for a file they are looking for. However we have over 100,000 folders that we are looking though. Is there a way to set the Search to...

One feature I really liked in XP was the ability to look in a folder through My Computer and sort the files by extension. For example if I wanted to get all .jpg files to one side of the folder as I looked for a file, I could click View, Arrange Icons By, Type and make that happen. I don't see...
