I need to retrieve information from a customer database which has been done using FileMaker 4.1. The only files available are files with extension .usr and when I open them using Filemaker, I have absolutly NO access to the data themselves, a windows is opened and I can navigate through a kind of application (a little bit like using Access when form are used, but I have no access to the data).

Could someone let me know what to do in order to access the data stored in this file?

Thank you in advance for your help.

Actually, I guess the .usr file are runtime database file and when I try to open the file an executable program is required. So what to do here?

The file format of a FileMaker database is a complex hierarchical BTree. The BTree is used to store data, layouts, scripts, and even images placed on layouts. I worked on the 3.0 version of the product and it took me several weeks to come up to speed on the format and using the internal functions to traverse the tree. I had the source, so fat chance trying to parse the format without it!

Your only choice is to open the file in filemaker Pro and use the export command off of the file menu to dump the data in a form acceptable to you. The export formats are pretty extensive and there is much flexibility in how it lets you put it out.

Good luck.
