recovery of mistakenly deleting files

I. Application of the recycling station
A file includes both the directory entry local and the data part on the disk. The directory entry contains the file name, extension, file size, set up and last modified time, the starting cluster number of the file data store, and so on. The data part contains the real data for the file. Everyone has the painful experience of accidentally deleting files or directories, but Windows 95 has taken a peaceful approach to maintaining accidentally deleted files, which is to apply the Recycle Bin.
The "Recycle Bin" theory is an implied directory of hard drives, and when users delete a file in a Windows system, when the user deletes it, Windows first drops the file into the implied directory, assuming the user wants to recover the file only to the Recycle Bin when the Restore command is selected. Unless the user voluntarily empties the Recycle Bin, or after a period of time, into the "Recycle Bin" file capacity beyond the "Recycle Bin" allowed capacity, the system will automatically be placed in the "Recycle Bin" files purged, otherwise these documents will be kept here for a long time, can be resumed at any time. However, the application of the "Recycle Bin" recovery mistakenly deleted files are still flawed, that is, under the Windows 9x DOS window or back to Dos under the Del, deltree and other commands to delete files from the "Recycle Bin" maintenance. And many users like to conveniently "Recycle Bin" empty, so that directly press the SHIFT key to delete files, then the file will be directly deleted, and will not be deposited in the "Recycle Bin." So the Windows Recycle Bin does not work.
Two. Application of temporary documents
Some applications in the running process, more or less always leave some temporary files, especially in the use of Office series software, only if you have a little attention, you will find in my Document folder a large number of similar "~wrl1233.tmp" files, In fact, these files are the product of Office automatic custody. After you accidentally delete a file, you can go to the folder to see, one by one open these temporary documents to try, may be able to find your needs. In addition, some software will save another in custody. Bak file, you can also turn to look.

Three. Application tool software recover mistakenly deleted files
At present, there are many such software, such as FinalData, Recovernt, and so on, here only to introduce the simple principle of FINALDTA and its recovery process.
FinalData is a file recovery program that can be used to restore important information that has been deleted, resulting in the ability to extract files from once formatted or damaged disks, allow recovery of a good directory, and try to stick to its original directory structure.
Of course not all the deleted files can be recovered. If the deleted file has been replaced by another file or the space occupied by the file data has been allocated to other files, then the file cannot be recovered. Thus, when the file is mistakenly deleted, assuming that the file is in the system partition (such as C disk), the first thing to do is to turn off the computer immediately to avoid the new operation masking the physical area of the original file, assuming that the deleted files are not in the system partition and the current partition does not exchange files, Then there is no need to immediately turn off the computer power. Also, it is assumed that files mistakenly deleted are not recoverable when there is a physically damaged hard disk (floppy disk). Know these, the following will introduce to you how to apply FinalData recover deleted files.

1. Start FinalData.
2. Click the "File" menu and choose "Flip" to render the "Select Drive" dialog box.
3. Select the drive where the deleted file is located, such as "E:", and then click the "OK" button, and FinalData will abort the regular scan for the drive you selected.
4. After the program scan will let you select the need to search the cluster range, can apply the "start" and "End" slider stop settings. Unless you do know the cluster where the deleted files are located, the initiative uses the system defaults, but this requires a longer scan time.
5. After the program search will stop the directory profiling, and in the program interface of the blank box in the search for all the files and folders, including the once deleted directory name and file, you can use the same as Windows Explorer to stop reading. However, the first character of the deleted directory and file name becomes "#" (assuming that you are deleting the entire directory, the first character of the file name in the directory will not be destroyed).
6. When you find the file that you want to recover, you can select one or more files, and then click the Recover button (Red Cross) on the tools bar, display the Safe Access dialog box, enter the custody path, and click the "Keep" button. The need to keep in mind that the driver of the custody path must not accidentally delete the file's drive. For users who need only one partition, it is assumed that the deleted file is not too large and can be kept on a floppy disk.
7. At the end of the custody, you can go to the explorer to see if the file can be kept in good condition. Assume that the first character of the filename becomes "#" and can be changed back to the original name.

Notice a little trick, assuming that a file is deleted at a DOS command prompt or through an application that does not support the Recycle Bin, the file will stick to its original filename. Assume that the file was first sent to the Recycle Bin and then removed from the Recycle Bin, the title of the file will be changed, its renaming rule is: D (that is, deleted, meaning to delete files) + its drive letter (such as e, meaning that the file is deleted from e disk) + deleted file serial number + original file name extension, If de13.txt refers to the file as a 13th file deleted from C disk, the file type is a text file (that is,. txt).
Demand FinalData friend to Baidu to find its download address, have to regret to inform the use of Windows2000 friend: FinalData not support Windows2000.

Four. Other ways of recovering mistakenly deleted documents
There are three ways to recover from mistakenly deleting files, and there are two other common methods for recovering mistakenly deleting files.
① uses a high version of DOS to provide a recovery delete file function of the external command-"undelete", but when you use it to recover deleted files, you need to specify the file name, file name allows to contain wildcards.
② when Windows does not start, assume that the requirements are restored to the Recycle Bin file What do you do? At this time first into the DOS mode, into the c:\\\\\\\\\\\\\\\\recycled directory, this is a hiding directory, assuming you want to restore the original file in D, the corresponding directory is d:\\\\\\\\\\\\\\\\recycled. The dir/a command enables you to list hidden files that begin with a bunch of DCs, which are the files you originally deleted. Because Windows changed the file name when it moved to the Recycle Bin, it also needed to retrieve the original file name. The original file name can be found in the INFO2 file in the recycled directory. INFO2 is a binary file in which each deleted file has a record (800 bytes) in the INFO2 file, where the file name can be found. The filename is arranged sequentially, and the first file name is dc1.*, and the file's original filename and extension persist unchanged. Assuming that the deletion is a directory, there is a recyled called DC???? directory, the same way to retrieve the original directory name.

false-formatted recovery

Because the formatter (refers to advanced formatting, such as DOS under the format program does not wipe the file data on the hard drive, but rewrite the fat table, as for the partition hard disk, but also modified the MBR and DBR, and the large part of the file data has not been destroyed, so many hard disk data can be restored. Of course, we can use some tool software to match the effective recovery of the data on the hard disk that has been formatted, but it is not easy to prevent it, and it does not guarantee that all data can be recovered.

I. Unformat
The Unformat program is available in a higher version of DOS, which restores the partitions that were once formatted. Although it can restore all the files, it will lose the hierarchy structure of the directory.

Two. FinalData
The process of using FinalData to restore the hard drive is the same as the recovery mistakenly deleted file described earlier. Select the drive you want to restore, and then the program will automatically show the contents of this drive, then you can create the directory and choose File to suspend custody, here to note that if you click on the folder is equivalent to create a folder , the files under it are not protected at this time.
