Unable to rename or copy files in Windows 8

Suddenly we can't rename files in folder nor copy them to the same partition. We are running windows 8 home. When we copy to the desktop and rename the file it works. We are getting the following error:

" The filename you've specified is either invalid or too long. Specify a different filename"

Any hints?

The file might be in use at the same time, so you can download unlocker as follow link,
and unlock the file and then rename it again, just try it , it might work


If unlocker is not working for your issue, you read the following articel to see any hint


Hope understand your question completely/ If not , please point it out

Try a checkdisk on that partition.

Means that you started check disk but it found no errors?
If so, you should conduct some quick tests:
-does it happen to work with the built-in administrator?
-does it work in safe mode?
-does it work from the command line?

Can you give us the command you are using to rename or are you doing this using Windows Explorer and then right clicking and renaming? Can you provide a few file names that are problematic or is it all file names?

-does it happen to work with the built-in administrator? No
-does it work in safe mode? Will try and let you know
-does it work from the command line? No

@Duncan: thanks for the links, i will try on Monday and let you know

@lionelmm: we are renaming thru the right click menu. the files are .jpg

Can you right click on one and check the permissions and let us see what those are with a screen shot? Thanks.

The NTFS rights are as per the below:

Domain Admins: full permissions
Domain Users: read/write/list

Thanks -

What about safe mode?
Lionel MMConnect With a Mentor Small Business IT ConsultantCommented:
I suggest you go to a command prompt (Start, Programs, Accessories, Command Prompt or type cmd in Run). Once there cd\foldername (where the jpgs are located); then type
ren filename.jpg newname.jpg
and let us know what happens.
