Computing questions

1.  I used the computer in the LRC and saved my word document as a doc file, but when I opened this file outside the LRC, it was unreadable and the text read like "V? D?: c?u b? l?i". Is there any way to recover it?

We’re sorry that it’s impossible to recover the file. The Unicode Code does not exist in Microsoft Word 95; therefore, the Vietnamese text can be deformed. Next time, you should select Microsoft Word 97/Xp/2003 when saving your file.

2.  How can I convert file odt into doc?

Open odt file using Open Office, select Save as. From “file type”, select Microsoft Word 97/2000/xp/2003 (Note: do not select Word 95), then save the file.
