|Applications are Evil||File Extensions Shell Help|
File Extensions Shell is the file type associations viewer, file finder, mass file extension changer, and file processing framework.
Administrative rights are required to perform installation and removal.
Uninstalling previous version is not necessary but recommended in order to remove registry entries that might have become obsolete in new version.
Use the provided installer to install and remove the product. Uninstallation preserves the existing extension descriptions.
Copy the product's file to desired location and register it with the regsvr32 utility:regsvr32 filext.dll
To uninstall the product, run regsvr32 with the -u option:regsvr32 -u filext.dll
then delete the file. You may need to logoff prior to deleting as the shell extension modules are usually locked by shell.
The name of a *.filext file may contain a dot; in such case the dot and the text after it is ignored and the text before dot is considered to be the extension name. For example, the file named txt.this describes the text files.filext behaves identically to a file named txt.filext.
This allows to give more descriptive names to the *.filext files. This is particularly useful when using the file processing framework.
Use one of the following methods:
To display the custom columns, from the menuclick and check the following columns:
The names of the columns start with a dot, providing mnemonic connection with file extensions.

You can also start the associated program by clicking.
File extensions can be bookmarked in Registry Editor. Clickfrom the context menu of the file extension description files, then open Registry Editor to navigate between the file extension keys without having to open separate Registry Editor window for each extension.
In addition to the extension's key the key of the extension's class is bookmarked, if exists.
The bookmarks are stored in the following registry key:
Note This operation deletes existing bookmarks.
Right-click an extension description file, then expandand select one of the listed web sites to query for the information about the extension.
Select an extension description file to query a web site and display its response in a preview pane. The web site to query is marked with bullet point inmenu. To change the web site click the corresponding menu item while holding <Ctrl> key. To switch the function on/off click item.
*Requires Windows Vista or later
To search a folder for files having specific extensions, select and right-click example files (see below), then from the context menu click(pic. 2).
A separate Windows Explorer window will open showing the files found in the current folder.
To search a folder other than current, drag example files with the right mouse button and drop them on the folder which you want to search, then from the context menu click(pic. 3).
An example file can be an extension description file (*.filext) or any file having extension:
|Pic. 2. Searching for *.exe in C:\Windows|
|Pic. 3. Searching for *.exe in C:\Program Files|
If renaming would result in overwriting existing files, then such files are not renamed.
Processing a file creates a copy of the file which differs from the original in some way; alternatively, the file is altered in place without creating a copy. You initiate processing by dragging and dropping a file to an extension description file (*.filext) which contains a script that does the processing.
|Pic. 4. Menu shown after a picture file is dropped onto a "bmp.filext" file|
The script defines two menu items: one to convert an image to another format (determined by the output file's extension) and the other to convert an image and additionally make it monochrome. The first menu item is the default which means that its command executes when a file is dragged with the left mouse button.
Each section of INI file corresponds to a menu item of a drag-and-drop menu. The structure of a section is described below:
|[Section name]||Can be any text.|
|Default||Specifies if the menu item is default (= 1) or non-default (= 0). The default command is executed when a file is dragged with the left mouse button.|
|Text||A text that appears on the menu item.|
|Command||A command that is executed when the menu item is clicked.|
The Text and the Command parameters can use macros which expand to the path of a dropped file and to the parts of that path. The macros are denoted with the angle brackets. The list of the supported macros follows:
|<SrcPath>||Full path to the dropped file||C:\some\dir\picture.jpeg|
|<SrcDrive>||The drive of the dropped file||C:\|
|<SrcDir>||The directory path, excluding the drive part, from where the dropped file was dragged||some\dir\|
|<SrcName>||The name of the dropped file, without extension||picture|
|<SrcExt>||The extension of the dropped file, without dot||jpeg|
|<TargetExt>||The name of the *.filext file before the first dot||bmp|
|<TargetDescr>||The part between name and extension of a *.filext file (if any)||48x48 (see example below)|
The Text parameter can only use the <TargetExt> and <TargetDescr> macros. The Command parameter can use any one of the described macros. In this example, because the converted file is dropped onto a bmp.filext file, <TargetExt> becomes "bmp".
The Command parameter can also use the operating system environment variables (denoted with leading and trailing percent character).
Note that the "<SrcPath>" is equivalent to the "<SrcDrive><SrcDir><SrcName>.<SrcExt>".
Instead of using <TargetExt> macro one could simply write "bmp"; however, because the target extension is not specified explicitly, the script can be copied without changes to other *.filext files, for example "png.filext" or "gif.filext", making those files convertors to the respective formats.
The <TargetDescr> macro utilizes a descriptive name feature.
The following example shows the use of a <TargetDescr> macro.
Text=Convert to '<TargetExt>' format and resize to <TargetDescr>
Command="C:\Program Files\ImageMagick\convert.exe" -resize <TargetDescr> "<SrcPath>" "<SrcDrive><SrcDir><SrcName>_<TargetDescr>.<TargetExt>"
Assuming that the script above is placed into a bmp.48x48.filext file, it converts a dragged file to BMP format and resizes it to be of 48x48 pixels size. The output file will have "48x48" suffix appended to its name.
The command exe.filext file is selected then the mask *.exe is copied to clipboard.from the context menu of a file extension description copies to clipboard a mask which specifies the files having the extension. For example, if
If more than one extension description file is selected then their masks are separated with semicolon. For example, if exe.filext, bat.filext and cmd.filext files are selected then the text *.exe;*.bat;*.cmd is copied to clipboard.
File Extensions Shell installs disk cleaner which is accessible through standard Disk Cleanup utility. It allows to delete all extension descriptions on selected drive.
