A quite large Excel file is suddenly blank and has a file size of 0. The file was fine yesterday, but empty today. It's stored on a Windows 2003 Server, but one that does not have shadow backups enabled. There is no other recent copy of this file.
Can anyone recommend or suggest a way to recover a previous version of the file (say from yesterday)? I assumed that shadow backups was enabled by default, I know now that it's not...
