data file
A bdat file is a binary data file. It contains data that is not in the form of text. The data is encoded for the purposes of computer storage and processing.
No. A copy remains in compressed form.
There many advantages of a file server they include: Data Security and Backups, Centralization of Data, Remote Access, User Control, Employee Monitoring and data recovery. For businesses a file server is essential.
the effects of file insecurity are: loss of data overwriting

Data file recovery retrieves deleted files by scanning the hard drive. When a file is deleted, its data is still capable of being recovered as long as the space it was in on the hard drive has not been rewritten.
File structures that remain after a file has been deleted
Your Private Data is recoverable using a File Recovery Program...such as Pixo_Rescue.
When you delete a file from the trash bin, the data is still there for the file but the reference to the file (the area on the storage device that shows where all the files are) is deleted. You can permanently delete a file by using a program, such as Eraser (http://www.tolvanen.com/eraser/) that writes random data where the file was.
You can try to recover your deleted files with recovery software.
creating a new volume and recovering the files from a backup source
There are many utility outside to recover deleted files. The one I used before includes asoftech data recovery, 001 file recovery.

If the file is "deleted" normally, the reference to that file will be moved to a section named the "recycle bin." The file must first be fully deleted by pressing Shift+Delete on the file, or by emptying the "recycle bin." When a file is fully deleted, It is marked by the system as free space, and the reference to the file in the index is removed. The actual contents of the file are left on the drive until that data cluster's space is used for storing a new file, at which time the old file is finally overwritten.
It depends on the operating system/file system, but most of the time, it stays exactly where it is and the computer just "forgets its address." That is, the data stays on the hard drive, but the computer erases the pointer to the start of the file. Until it is overwritten by a new file (the time it takes for this to happen is highly variable), there are tools that can recover the data.
Without extraordinary measures, they are not deleted. Windows removed the index for a file, not the file itself. The data remains on the hard drive. To some extent, this is true in most other operating systems as well. You can get special programs which not only delete files but overwrite them with nonsense data. In some cases, they will even do this multiple times, making it next to impossible for even the most sophisticated tools to recover the deleted file.
