To unlock files easily, use the “Unlocker Assistant”:

There is a portable version and an installable too. This tool makes it very easy to identify which process is locking a given file, and it can attempt to kill the process, or just undo the lock.

There is also “EMCO Unlock IT” which does extremely well:

Great photo organizer and viewer
article #1095, updated 19 days ago


Open source, cross platform, amazingly good. Install it, choose all defaults, then immediately Settings / Configure digiKam, choose Collections on the left, and add each folder containing images. Then the program will search for and cache thumbnails for all of them. Direct camera/phone connection support, and file and folder management too.

Symbolic Links (symlinks) in Windows
article #371, updated 32 days ago

In Vista or Windows 7, there is a built-in command, “MKLINK”. Here’s a good reference, suggested by Matt Quick:

For a long while they were called “junctions”. In Server 2000, Server 2003, or XP, you’ll need this:

The syntax is a bit different for each. And Windows does not support these “junctions” to directories on remote shares. But this can help a lot, for instance, when moving something like a profile folder from local drive to local drive. They are set up at the NTFS filesystem level, just like Unix/Linux.

A great example of usage, is moving a profile folder. It works like this:

  1. Create a new user, local if it’s not a DC.
  2. Reboot the server/PC, to unlock profile files and folders.
  3. Log in as the new user.
  4. Create a new folder for the profile to be moved.
  5. Robocopy the old profile folder’s contents to the new. Make sure you get everything hidden!
  6. Rename the old folder as backup, and create a junction from the new folder to the old folder’s container.
  7. Log in as the new user and test.

Excellent vector graphics designer and editor, free of charge
article #1072, updated 78 days ago

I just tried several, including my old friend Inkscape. Gradient editing is broken partly or completely, and/or far arcane and undocumented, in everything I tried, except one new one:

Gravit Designer. Install it as a program on major platforms, or use it online, or both. Amazingly good.
