SVN error "working copy xxx locked" and there is no .lock file
svn
Solution
SVN uses hidden directories, .svn or _svn by default. Before resorting to tinkering with these folders:
Usually the best thing you can do is fire up a copy of TortoiseSVN (http://tortoisesvn.net/) and hook it to your repository and working directories. Tortoise hooks into Explorer so it gives you a bit more holistic view of your working folder structure. Try the Unlock command on the files/folders, in question. If this works, (or doesn't) Follow up with a "Cleanup" against the parent folder for the item in question (1 folder level higher) and then try the desired operation again.
If you're using Ankh or a similar VS plugin these kind of locking issues can be fairly common, and annoying. :)
Problem
My working copy is locked and search for solution about it, and I found one that says .lock file should be removed. But the problem is there is no .lock file created in my folder. How to solve this. Please help. Thanks.
