Can't open a project 2007 file I created

**sayeed** · 25-09-2008

I have made a project schedule about a week ago under Project 2007 and I have opened it with minor edits over the past couple of days without any problems. Today when I tried to open the file, then I was getting an error message that states "Project cannot recognize this format". I am able to open other project files but not this one? Can anyone tell me how do I open this file properly? Thanks.

You can try to open a new blank file and insert the project into it. Incase you can open it, then you can also try the suggestions given below:

First of all you can try to open your problem file (it may help to turn off automatic calculation if the file is reluctant to open).
Afetr that select File/Save As...
Now, you have to save as type: Project Database (*.mpd) then click Save.
After that close the file.
Now, try to re-open it from the .mpd file.
Lastly, you can select File/Save As... and save it as an .mpp file again.

Tried the suggestions to no avail...

Here is a bit more detail on the file I can not open:
Just a task list of approximately 300 tasks, not networked yet, no dates either...just a straight list of tasks (which will be difficult to remember...shame on me)

I did notice something however when I "mouse over" and different project file (in a directory folder). The following data is displayed: Type, Author, Title, Date Modified, Size. However when i mouse over the file I can not open only Type, Date Modified, and Size are displayed...

I have a similar situation but saved after every 5 tasks. After one of these saves (it took 30+ seconds) the file was 1.6 GB+ and then Project had an error and ended. Now the file will not open (too many lines, too large). Is there a way to edit the file outside of Project (2007, saved as 2000-2003) to reduce the size?

I also can't open a MSP 2007 file I created.

Using MSP 2000 at work I can't open the file I created on my laptop using MSP 2007 even though I saved it as 2000-2003 format. There doesn't seem to be a save as '98 version, how would you suggest I open this file?
