WARNING: Microsoft does not guarantee that any deleted Microsoft Excelfile can be recovered, or if recovered, that the file will be reliable.
The method that you use to recover a deleted file is dependent on theoperating system that you are using. To recover a deleted file, you needa utility program to accomplish the task.
MS-DOS, versions 6.0 and later, ships with a utility called Undelete,which you can use to recover deleted files. However, the followingoperating systems do not ship with a utility to recover deleted files:
MS-DOS 5.0 and earlier Macintosh (all Systems) Windows NT Windows 95
Windows NT does not allow deleted files to be recovered, and therefore,no undelete utilities are available.
Third-party programs are available that can recover deleted files.
For more information about undeleting files, consult the manual includedwith your operating system or your undelete utility.
The probability that you will have success in recovering a deleted filedepends on the amount of disk activity that has taken place since thefile has been deleted. In general, you have a better chance ofrecovering a deleted file if you attempt to undelete it immediatelyafter the file is deleted.
