Extract content of .dump file

We have been provided a .dump file.The need is to extract the contents(may includes files and folder).
ls -lZ didnt help me as Z is not a valid option.
How to extract the file contents ?

Is this an ufsdump archive? In such case, you can list its content with:

ufsrestore ta filename.dump

Otherwise, what says:

file filename.dump

?

ufsrestore ta <file_name>.dump
Volume is not in dump format

OK. So we now know that this is not a ufsdump dump file.

So, as jlliagre suggested, what is the output from the command:

file filename.dump

IF we cannot know the file type (what application/utility created the file in the first place) we cannot help you.

when i did as mentioned above i found then type as follows

<file_name>:    commands text

I suspect it is a text file then.Please correct me if wrong

That's a good guess.

What makes you feel this file contains itself files and directories that need to be extracted?

Did you look at its contents? eg:

less filename.dump

yes i just realized that as its been created in SVN repository, it needs to be extracted in a different manner than usual.

svnload admin <path_to_extract> < file.dump

thanks all for your help
