Breaking news: we’ve just released AB Commander version 7.7!
What’s new in this version:
- The Wipe the content option has been added to the Delete command. You can use this option to make it much harder (if not impossible) to reconstruct the contents of the files being deleted.
- The file management commands (Copy, Move, Delete, etc.) are now performed asynchronously. For example, if you’ve started a long operation to copy a large file, you can continue working with AB Commander without having to wait for the copying to finish.
- The Undo command has been added to the Command menu. (Previously, it was only accessible via the Ctrl-Z key combination).
- Several other minor improvements and corrections have been made.
Take control of your files and folders with AB Commander file manager for Windows 10,8,7,Vista, and XP.

If you used Space Investigator to analyze the contents of your C: drive, you probably couldn’t help but notice a rather large file named hiberfil.sys in the root folder. This file is used by Windows to remember the state of your computer when you hibernate it.
OK, but what if you never hibernate your computer? (In most cases sleep is what it does, which is not the same as hibernate). The size of this file is about the same as the size of the RAM your computer has, it would be nice to delete the file and allow other files use that space. However, if you attempt to delete the file directly (using Space Investigator, AB Commander, or Windows Explorer), you might be surprised to discover that Windows does not let you delete it, even if you use your full powers of the administrator.
To solve this problem, you need to disable hibernation: when you do that, Windows deletes the hiberfil.sys file for you. Windows XP offers a special button in its Control Panel that you can use to disable or enable hibernation. However, Windows Vista and Windows 7 for some reason don’t offer a similar command. Fortunately, there is a way to disable or enable hibernation: by running the powercfg.exe command with the administrative privileges and the appropriate command line switches, as described in this Microsoft article.
If you have AB Commander, you might be surprised to know that it can be used to achieve the same result especially easy. To do this, you need to know three things:
- AB Commander lets you launch any command by entering it into its command bar (at the bottom of AB Commander window).
- You can start a command elevated (a.k.a “As Administrator”) by pressing the Ctrl+Shift+Enter keys.
- You have to know the correct command (and any parameters, if applicable) to run to perform the specific task you want.
For turning the hibernation on and off, the above mentioned Microsoft article gives us all information we need:
To disable hibernation, run this command:
powercfg.exe /hibernate off
To enable hibernation back, run this command:
powercfg.exe /hibernate on
Remember to launch these commands “As Administrator”, or they won’t work:

We goofed! In the previous version 7.5.6, we’ve added a few additional checks of the license key validity and it turned out one of them was one too many: it caused a message asking the user to enter a valid license key to appear in some circumstances, even though the correct license key was already entered.
To correct this error, we’ve released an updated version 7.5.7 today. (It has no other improvements over 7.5.6, so if you don’t see that message, feel free to skip this update). If you do want to upgrade, you can install the new version without removing the previous one, and it should upgrade the files and retain your settings.
This is a minor update that fixes a problem that caused the drive bar of the toolbar to move to the second row if a removable drive was attached to the computer while AB Commander was minimized. Download the update…
We’ve just released a new version of AB Commander 7.5.
This version adds several new features, such as the ability to navigate to any of the parent folders by clicking on their names in the panel title bars, or the use of the CTRL+WINDOWS key combination to quickly exit, minimize, or iconize AB Commander. This version also adds integration with our new product USBCrypt: now when you stop a Virtual Encrypted Disk created with USBCrypt, AB Commander releases its resources automatically.
As before, our usual upgrade policy applies: if you have purchased an AB Commander license within the previous 12 months, you can upgrade to this version free of charge: just download and install the new version, it should replace the previous version automatically for you. Otherwise, please visit the Upgrade Center to receive the automatic 50% upgrade discount.
Should you have any questions or comments, please don’t hesitate to contact us.
Happy file commanding!
