FileTypesMan is an alternative to the 'File Types' tab in the 'Folder Options' of Windows.
It displays the list of all file extensions and types registered on your computer.
For each file type, the following information is displayed: Type Name, Description, MIME Type, Perceived Type, Flags, Browser Flags, and more.
FileTypesMan also allows you to easily edit the properties and flags of each file type, as well as
it allows you to add, edit, and remove actions in a file type.
This utility works on any version of Windows from Windows XP to Windows 11.
For using this utility under x64 system, you should download the x64 version.
Crash/hang on Loading Icons...
If FileTypesMan crashes or hangs on your system while loading icons ('Loading Icons...' message is displayed in the status bar),
you should run FileTypesMan with /DontLoadIcons command:
FileTypesMan.exe /DontLoadIcons 1
Known issue with 'Choose Icon' window on some Windows 10 systems
Some people reported that in the latest updates of Windows 10, when trying to select an icon by clicking the '...' button of the icon field, the FileTypesMan tool stops responding.
I tried to reproduce the problem on my systems, but in all tests this 'Choose Icon' window worked completely fine.
Moreover, the 'Choose Icon' window is displayed by calling API of Windows operating system (PickIconDlg)
, so this bug is actually a problem of Windows operating system, it's not a bug inside FileTypesMan.
If you know the filename and the icon number you want to choose, you can type it directly inside the field without using the 'Choose Icon' window.
- Version 1.98:
- Added option to change the sorting column from the menu (View -> Sort By and Actions -> Sort By).
- Added 'Sort By' buttons to the toolbar.
- Version 1.97:
- FileTypesMan doesn't allow you anymore to change the 'Default Icon' for .exe extension. It's because many people try to modify the icon of .exe files and then
ask my help in order to revert it back...
- Version 1.96:
- Fixed the find dialog-box to work properly when you press the Del key.
- Version 1.95:
- Added 'Copy Selected Actions' and 'Paste Actions' options, which allows you to copy one or more actions into the clipboard and then paste them into another file type / extension.
- Fixed bug: When a file extension had a 'User Choice' entry that cannot be accessed , FileTypesMan displayed and edited the actions of the file type, instead of displaying 'Access Denied' error message.
- Version 1.90:
- Added 'Run As TrustedInstaller' option (Under the Help menu). You can use this feature to view and modify file types that their owner is TrustedInstaller, like the Windows Media Player menu items of .mp3 file extension.
(If you try to modify TrustedInstaller entries without running FileTypesMan as TrustedInstaller, you'll get the 'Access is denied' error message. )
- Added 'Registry Key Owner' column for both upper pane and lower pane. When the Registry Key Owner on the lower pane is 'NT SERVICE\TrustedInstaller' , you have to run FileTypesMan as TrustedInstaller in order to modify
the file type action. Otherwise, you'll get 'Access is denied' error message.
- Version 1.86:
- You can now use the combination of /SelectedExt command and the save command-line options (/scomma, /shtml, and so on...) to
export from command-line the actions of specified file extension.
- For example, in order to export to csv file all actions of .txt extension:
FileTypesMan.exe /SelectedExt .txt /scomma "c:\temp\txtext.csv"
- You can now send the file types information to stdout by specifying an empty filename ("") in the save command-line options. (For example: FileTypesMan.exe /scomma "" | more)
- Version 1.85:
- Added 'Icon' column to the lower pane.
- Added Icon field to the 'Edit Action' window.
- Version 1.83:
- When you run FileTypesMan, it now automatically selects the last selected extension.
- Added /SelectedExt command-line option for selecting the desired extension in the upper pane, for example:
FileTypesMan.exe /SelectedExt ".txt"
- Version 1.82:
- Added 'Icon Handler CLSID' column. When a file type has an icon handler, the icon handler set the actual icon that will be displayed for the file, instead of the 'Default Icon' value.
- Version 1.81:
- Added Drive and Directory\Background types.
- Fixed bug: FileTypesMan displayed incorrect Registry keys for Directory.
- Version 1.80:
- Added 'Detach File Type' button to the 'Replace File Type For Selected Extension' option, which allows you to detach a file type from the selected file extension and
leave the file extension as a standalone extension without a file type.
If you detach a file type from a file extension, changing the icon and menu items won't affect other file extensions (Be aware that you may also need to clear the
'User Choice' field, if it's not empty)
- Added '...' button to the 'User Choice' field, which opens a window that allows you to easily choose the desired file type.
- Fixed FileTypesMan to use the correct file type Registry key, when there is a CurVer subkey that redirects to other file type key.
In previous versions, FileTypesMan failed to change the icon and menu items of .pdf and other extensions due to this bug.
- FileTypesMan now stores the selected font in the .cfg file.
- FileTypesMan now displays an error message if it fails to modify action or file type.
- Version 1.72:
- Fixed a crash problem occurred while loading the icon of .appref-ms extension, on some systems.

Start Using FileTypesMan
FileTypesMan doesn't require any installation process or additional DLL files.
In order to start using it, simply copy the executable file (FileTypesMan.exe) to any folder you like,
and run it.
After running it, you should wait a few seconds until the file types list is loaded.
If the loading process is too slow, it's recommended to turn off the icons loading (Options->Don't Load Icons in menu),
so in the next time that you run FileTypesMan, the loading process will be faster.
The main window of FileTypesMan contains 2 panes.
The upper pane displays the list of all extensions/file types registered on your computer.
When you select a single file type in the upper pane, the lower pane displays the list of all actions of
the selected type.
'Replace File Type For Selected Extension' option (F4)
Sometimes, when you install a new software, it automatically replaces the file types associated with various file extensions.
This means that when you double-click the file, the new installed application is opened, instead of the old one.
The icon of the extension is usually also replaced to the icon of the new application.
The 'Replace File Type' feature allows you to set the file extension back to the original file type.
In order to do that, select the desired file extension in the main window of FileTypesMan, and press F4.
You'll get a long list of available file types on your computer. Find and select the previous file type
that handled the extension, and choose 'Ok'.
Each time that you make a change in the properties of a file type, FileTypesMan
automatically initiate a general desktop refresh, so your changes will take affect immediately,
even for opened Explorer windows.
However, on slow computers, this desktop refresh might consume a fair amount of CPU resources, and
even hang the entire operating system for a few seconds.
If you want to avoid this desktop refresh on every change that you make, simply
disable the automatic refresh, by unchecking the option under the following menu: Options->Automatic Desktop Refresh.
You can always initiate a desktop refresh when you need it, simply by selecting 'File->Refresh Desktop Now' from the main menu.
Sending extension information to extension.nirsoft.net
a Web site that allows you to find out which programs can open a specific file extension.
If you want, you can add the extension information stored in your computer into extension.nirsoft.net Web site, by using the 'Send Report to extension.nirsoft.net' option under the Help menu.(Ctrl+F9).

FileTypesMan.exe /SelectedExt ".txt"

FileTypesMan.exe /SelectedExt .txt /scomma "c:\temp\txtext.csv"
/DontLoadIcons <0 | 1>
Specifies whether to load the icons from the file type dll. 0 = No, 1 = Yes.
If FileTypesMan crashes while loading the file types list, running FileTypesMan with '/DontLoadIcons 1' command may solve the problem.

This command-line option can be used with other save options for sorting by the desired column.
If you don't specify this option, the list is sorted according to the last sort that you made from the user interface.
The <column> parameter can specify the column index (0 for the first column, 1 for the second column, and so on) or
the name of the column, like "Type Name" and "Extension".
You can specify the '~' prefix character (e.g: "~Extension") if you want to sort in descending order.
You can put multiple /sort in the command-line if you want to sort by multiple columns.
FileTypesMan.exe /shtml "f:\temp\types.html" /sort 2 /sort ~3
FileTypesMan.exe /shtml "f:\temp\types.html" /sort "Extension"
When you specify this command-line option, the list will be saved without any sorting.
