Free to handle software for windows

Handle - show you what files are open by which processes, and much more Ever wondered which program has a particular file or directory open? Now you can find out. Handle is a utility that displays information about open handles for any process in the system. You can use it to see the programs that have a file open, or to see the object types and names of all the handles of a program.
Handle is targetted at searching for open file references, so if you do not specify any command-line parameters it will list the values of all the handles in the system that refer to open files and the names of the files. Handle can also take several parameters which modifies this behavior.
usage: handle [[-a] [-u] | [-c ] | [-s]] [-p | > [name]
-a
Dump information about all types of handles, not just those that refer to files. Other types include ports, Registry keys, synchronization primitives, threads, and processes.
-c
Closes the specified handle (interpreted as a hexadecimal number). You must specify the process by its PID.
WARNING: Closing handles can cause application or system instability.
-s
Print count of each type of handle open.
-u
Show the owning user name when searching for handles.
-p
Instead of examining all the handles in the system, this parameter narrows Handles scan to those processes that begin with the name process. Thus:
handle -p exp
would dump the open files for all processes that start with "exp", which would include Explorer.
name
This parameter is present so that you can direct Handle to search for references to an object with a particular name. For example, if you wanted to know which process (if any) has "c:windowssystem32" open you could type:
handle windowssystem
The name match is case-insensitive and the fragment specified can be anywhere in the paths you are interested in.
When not in search mode (enabled by specifying a name fragment as a parameter), Handle divides its output into sections for each process it is printing handle information for. Dashed lines are used as a separator, immediately below which you will see the process name and its process id (PID). Beneath the process name are listed handle values (in hexadecimal), the type of object the handle is associated with, and the name of the object if it has one.
When in search mode, Handle prints the process names and ids are listed on the left side and the names of the objects that had a match are on the right.

Firefox extension that will resolve CNRI Handle (hdl) and Digital Object Identifier (doi) URIs Mozilla Handle/DOI Protocol Handler will allow Firefox to resolve CNRI Handle (hdl) and Digital Object Identifier (doi) URIs.
Mozilla Handle/DOI Protocol Handler accomplishes this by forwarding requests to one of two proxy servers:
- http://hdl.handle.net/ for hdl: URIs
- http://dx.doi.org/ for doi: URIs
This is the common method of enabling browsers to resolve handles via HTTP.
System requirements:
- Firefox: 1.5 ? 2.0.0
