I've had a fair bit problems with sometimes files/folders/processes being 'locked' by Windows.

The weird thing is, it's not like the traditional sense, I think, where tools like UnlockIT and wholockme would work. It seems that just giving it a little often helps - making me think it could either be the HDD, the memory, or something in Windows.

A scenario: I go into a folder - don't open anything at all, go back up, cut or drag-move the folder to someplace else, it says "Action can't be completed because the folder or a file in it is open in another program".

Waiting sometimes 20 seconds sometimes a little longer, and I can move it.

Another scenario is deleting a bunch of files in a folder, and it appears that everything is gone, but then suddenly after a few seconds an .exe file pops back up, and I can't delete it. Waiting a few minutes, then pressing refresh and it's gone.

I have the strangest feeling that there's a problem with either HDD or memory.

I already tried disabling Windows indexing service with no luck.

Does anyone have any ideas?

EDIT: I should say, that I have a very fast system, 16 GB DDR3 RAM, i7-2600k CPU, SSD main HDD, so I really should not be experiencing any sort of problems, where one might say that it's "reasonable" for the system not to respond right away.

Edit2: And I updated SSD firmware a couple months ago, so it shouldn't be bad release FW either
