From your despcription it looks like you have save the file and then open the file but data is not coming. but during closing the file you thought that you saved the file but data is not coming if it is so :
Yet, you may be able to recover it or at least some part of it.
To do this: Open the
Tools menu. Click Options. Click the
File Locations tab. If the space next to AutoRecover
files is blank, then your data is lost. If there is a location, go to
that location and open the document.
How to turn on
AutoRecovery:
Select Tools,
Options, Check 'Save AutoRecover info every:'
and provide the interval.
Then click on the File
Locations tab, Select AutoRecover Files, Click on
"Modify..." & provide a location for its to save the
files.
How does it work:
When AutoRecover is turned on, the changes
you make are saved at set intervals in a separate, temporary recovery file.
Then, if you have to restart Word or your computer without saving your work,
Word automatically opens the recovery file. In some cases it doesn't. In such
situations you have to try out the above solution. The recovery file contains
your changes up until the last time AutoRecover saved the document. For example,
if you set AutoRecover to save every 7 minutes, you don't lose more than 7
minutes of work. All documents that were open at the time of the power failure
or similar problem appear for you. Only changes you made after the last
AutoRecover save are lost.
