Questions and answers

  • What is ".CTG Recovery" and how does it work?

    ".CTG Recovery" refers to a file recovery software called "CTG File Recovery." It is a program designed to help users recover deleted or lost files from various storage devices, such as hard drives, external drives, memory cards, and USB drives.

    When files are deleted or lost from a storage device, they are not immediately erased from the device. Instead, the space they occupy is marked as available for new data. CTG Recovery works by scanning the storage device for these marked spaces and attempting to recover the files that were previously stored there.

    The software uses advanced algorithms to analyze the device and locate the remnants of deleted files. It can recover various types of files, including documents, photos, videos, audio files, and more. CTG Recovery also supports different file systems, such as NTFS, FAT32, exFAT, and others, making it compatible with a wide range of storage devices.

    To use CTG Recovery, you typically need to download and install the software on your computer. Once installed, you select the storage device you want to recover files from and initiate a scan. The software will then analyze the device and display a list of recoverable files. You can preview the files before recovering them to ensure you are restoring the correct ones.

    It is important to note that the success of file recovery depends on various factors, such as the condition of the storage device, the length of time since the files were deleted, and whether any new data has been written to the device.
