Unlocker 1.8.9 removes a file's access restrictions

This single-function system utility removes a file's access restrictions, but lacks some common features. Unlocker is unobtrusive: it resides in the system tray; an Unlocker command appears in files' right-click menus.

The application removes file-access restrictions that prevent a user from moving, deleting, or renaming a file. The user right-clicks on a file and selects Unlocker, which displays information regarding the selected file, such as Path Locked, PID, Handle, and Process Path. This program also allows terminating a currently running process. In some cases, files cannot be accessed due to Windows file-access bugs, for which Windows informs the user the file is currently in use--even when it's not.

Unlocker can effectively bypass this bug's restrictions; it unlocks or disables whatever is preventing the user to access that file. This tool would be a lot easier to use if it allowed hot keys. Novices to advanced users will find this free application very useful.

WinMount is a powerful windows utility which is dedicated to managing compressed archives and image files impressivesly and conviniently. It can be used to mount ZIP, RAR, ISO,etc archives very fast, which enabling you to use the files inside it directly without needing extract it beforehand. Such convenience, therefore, saves your time and disk space dramatically. In addition, WinMount, serving as a CD-ROM OR DVD-ROM emulator, supports almost all image file formats, which including but not limited to ISO, CUE/BIN, CCD,BWT, MDS, CDI, NRG, PDI B5T and ISZ.

WinMount's Feature:
• ISO
• CUE/BIN
• MDS/MDF (Media Descriptor File)
• ISZ (Compressed ISO images)
• NRG (Nero)
• CCD (CloneCD)
• BWT (Blindwrite)
• CDI (Discjuggler)
• PDI (Instant CD/DVD)
• B5T (BlindWrite 5)

File Synchronization With Free File Sync

File synchronization can come in handy in several situations. Think of users with multiple computer systems, e.g. a desktop PC and a laptop or netbook. File synchronization can help them to synchronize emails, bookmarks, spreadsheets and every other kind of data that was created or changed on one of the computer systems. It can also be used for backup services by automatically synchronizing the data of the main computer system with a backup server or external storage device.

Free File Sync is an Open Source file synchronization software that’s above everything else super-easy to use. The main interface is separated into a left and right column. Directories can be added to each column. The two main actions offered by Free File Sync are to compare or synchronize the directories and the files residing in them. A click on the Compare button at the top will generate a directory and file listing for every directory that has been added to the application.

All files and directories are displayed in both columns with a blank row in the opposite column if the file or directory does not exist there. Information about each file including its name, size and modification date are displayed in the table as well. Arrows in the middle indicate the action (e.g. overwrite file in the left column, copy file to the right column) are taken if the Synchronize button is pressed.



Statistics for each column are displayed in the footer listing the number of directories, files and the size of the data conveniently. There are also general statistics about the total number of files and folders that would be created if the user would synchronize the files. Several advanced options are available. The file synchronization program supports file filters and several different ways of comparing and synchronizing files. Files are initially compared by name, size and date which can be changed to a file content comparison instead.

Four different file synchronization options are provided by Free File Sync as well with automatic synchronization of both sides selected by default. This can be changed to mirror files that reside in the left folder to the right folder, copy or update files from the left to the right folder or a two way synchronization which synchronizes both sides simultaneously.



A batch job can be created using the parameters configured before. Batch jobs can be executed by starting the file synchronization software with the file name of the batch job as a parameter. This makes it also possible to add the file patronization as a scheduled task in the Windows Task Scheduler.

Free File Sync is easy to use. It takes only a few minutes the most to compare or synchronize files and another few to create a batch file to sync files regularly with little to no user interaction. The program is available at the Sourceforge website where it is available for 32-bit editions of Windows and Ubuntu.

Use DjVuLibre to view any document faster

DjVu (pronounced "déjà vu") a set of compression technologies, a file format, and a software platform for the delivery over the Web of digital documents, scanned documents, and high resolution images.
DjVu documents download and display extremely quickly, and look exactly the same on all platforms with no compatibility problems due to fonts, colors, etc. DjVu can be seen as a superior alternative to PDF and PostScript for digital documents, to TIFF (and PDF) for scanned bitonal documents, to JPEG and JPEG2000 for photographs and pictures, and to GIF for large palettized images. DjVu is the only Web format that is practical for distributing high-resolution scanned documents in color. No other format comes close.

Typical DjVu file sizes are as follows:

bitonal scanned documents: 5 to 30KB per page at 300dpi (3 to 10 times smaller than PDF or TIFF)
color scanned documents: 30 to 100KB per page at 300dpi (5 to 10 times smaller than JPEG).
photos: 2 times smaller than JPEG, about the same as JPEG-2000, but the decoder/renderer is progressive and has minimal memory requirements.
palettized images: 2 times smaller than GIF (up to 10 times if it's mostly text).
digital (non scanned) documents: between 1 and 3 times smaller than PDF or gzipped PS (depending on the amount of pictures), but rendering, page flipping, zooming, panning are incomparably faster, and the image quality on screen desplays is much better (antialiased text, etc).
More importantly, all DjVu images render very quickly and can be smoothly zoomed and panned. Pages of a document can be turned instantly, with no annoying delay.
DjVu is used by hundreds of academic, commercial, governmental, and non-commercial web sites around the world to distribute scanned documents, digital documents, and high-resolution photos.

A short technical description of DjVu is available here.

Demos, and general information about DjVu can be found at DjVuZone.org, or at LizardTech.com.

DjVu was originally developped at AT&T Labs-Research. In March 2000, AT&T sold DjVu to LizardTech Inc. who now distributes Windows/CE/Mac plug-ins, and commercial encoders.

DjVuLibre is an open source implementation of DjVu. See the credits/history page for more details.
