The .lrcat.lock file is in the exact same folder as your Lightroom Catalog file.

How do you delete the locked file?

The answer has been given in several posts in this thread, like here: Re: Lightroom catalog cannot be opened because another application already has it opened
Or see this article, Lightroom basics - scroll down to "Some common problems".

I can not tell you how many times LightRoom 3.5 or earlier just freezes under Win 7-64 bit. You can not CTL+ANT+DEL or anything else but manual shut down. This typically occurs when user enters something before a LightRoom task is completed. It is not acceptable!
When rebooting, anything might have happened but usually nothing. I failed to notice a lost folder of all 2011 photos. This occurred just after my last backup so some delay before even noticing since I was working on older folders. So all are now gone.
The most recent freeze was the typical several minute wait while loading the catalog and reading the camera's card. The inevitable reboot left the catalog locked so it was easy to simply delete the lock file after nearly an hour getting to this suggestion. Maybe we are using oppisite sides of the brain but the delete lock file suggestion would help on the actual error message. The real problem is frequent lock ups! Do you think enough 64 bit users might dump this product with similar lock ups / lost files or folders and long research time to find a solution? Release 4 is not looking likely!

I am presently having this same issue but cannot find any files with "lock" at the end to delete. Any other suggestions? I'm really in a bind as I needed the program to finish some baseball collages, etc and time is limited. Any help ASAP would be greatly appreciated.
Thank you

Thank you! Worked perfectly for me!
(Original post from 2008, and here I am in late 2014 using the same solution... C'mon, now, Adobe, it's not like this is a new problem.)

Great! Now I am getting an error that says my catalog cannot be opened because it is not writable. I first was getting the file locked error from this thread. Then, I deleted the .lock file for my catalog and now this new error appears. Seems like I am having a lot more problems lately. Is it me?

Not writable means that the folder it is in (or the file itself) does not have write permission. Change your permissions!

Where are the permissions? I deleted the lock file, reopened old catalog, saved that and still get the error code that the file may be in use or unwritable. Thanks..p.s. This only started for me with lr6 cc

Permissions are something you set and change using your operating system.

Thanks.. For some reason lr is saving as zipped and I have to open that file each time to share. Never had this problem before. Am a neophyte..where in operating system do I go to change? Thanks

And why does it create a locked file every time?

Let's back up a minute, rsbjsb
Please describe your problem in detail. Please make sure you mention your operating system, and your version of Lightroom.
