How can I open a file marked .txr?

Question

Specifically, I tried to open a MySpace IM saved conversation, and it is not in any format I have ever seen, and I cannot open it. At least, not in any readable way.

Answer 1

Well here is an easy way
Open any folder in Your computer
look up and chose tool....Then click on Folder Option,,,Then click on View

Then at the Option.
Hide extensions for known File and Types
if that Option is Empty click on it
and Then Press Apply

Now go to the File you want to open
One click on it
Right click,,,,,chose Rename
Then when you have to rename all you have to do is go by the arrow to the end of the file name and Add .txt
and then click anywhere out
Then you will be able to open the File
but no matter what the file type is
add .File type name
it will work
Peace out

The Tcl Dev Kit Cross Reference Tool (XRef) is a graphical browser that maps out the structure of a Tcl program and helps make complex code more understandable. The XRef tool scans Tcl source code, and then builds a cross-referenced database showing you the relationships among Tcl code components. These components include packages, files, namespaces, commands, and variables. Each Tcl component is presented in a tree hierarchy that can be expanded to display where the code is defined, declared, used, and located.

The XRef tool is useful for building, debugging, and maintaining Tcl code. For example, when changing a variable definition, use the XRef tool to identify the files and commands where the variable is declared, and then update them to the new variable definition.

The Tcl Dev Kit Cross Reference Tool can be used to extract Tcl component information from programs and packages contained in TclApp (or Prowrap) projects, Tcl Dev Kit Package definitions (".tap" files), and from Komodo project files.

Cross Reference Tool features include:

Switching between hierarchical views to gain a higher-level or lower-level understanding of any Tcl source component.
Drilling down into specific areas of code.
Finding dependencies between commands, variables etc.
Browsing from a listed namespace, command, or variable definition and jumping to the actual source code where it is declared. Note: XRef will launch Tcl source code in the Komodo editor if it is installed.
Filtering components based-on packages, files, namespaces, commands and variables.
At-a-glance overview of code areas that could be affected by changing a command or variable definition.
The XRef BWidgets demo uses the Cross Reference Tool to extract component information from the BWidgets package. See the XRef BWidgets Demo for more information.
