Features
Often when we try to delete a file or folder in Windows, we see annoying messages such as "Cannot delete file: Access is denied;" "Cannot delete folder: It is being used by another person or program" "There has been a sharing violation;" "The source or destination file may be in use;" "The file is in use by another program or user;" "Make sure the disk is not full or write-protected and that the file is not currently in use;" or "Cannot read from the source file or disk." This is usually because the file or folder is in use by another program or user. IObit Unlocker is designed for such situations. It releases the file or folder that's in use by other programs and allows you to quickly remove or modify it.

IObit Unlocker Portable is packaged in a PortableApps.com Installer so it will automatically detect an existing PortableApps.com installation when your drive is plugged in. It supports upgrades by installing right over an existing copy, preserving all settings. And it's in PortableApps.com Format, so it automatically works with the PortableApps.com Platform including the Menu and Backup Utility.
