FolderTimeUpdate is a simple tool for Windows that scans all files and folders under the base folder you choose, and updates the 'Modified Time' of every folder according the latest modified time of the files stored in it.
This tool might be useful if, for example, you backup a cluster of folders and then restore them into another disk, but the backup program doesn't restore the original modified time of the folders.

System Requirements

This utility works on any version of Windows, starting from Windows 2000 and up to Windows 11. Both 32-bit and 64-bit systems are supported.

Start Using FolderTimeUpdate

FolderTimeUpdate doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - FolderTimeUpdate.exe

After running FolderTimeUpdate, you can choose the desired base folder and the other options and then click the 'Start' button to start updating the modified time of all folders.
If you're not totally sure that the 'Modified Time' change is right for you, you can choose the 'Simulation Mode' option. When 'Simulation Mode' is on, FolderTimeUpdate will only display the changes of the modified time that will be made for all folders, but without actually applying these changes.

Command-Line Options

Starting from version 1.35, you can update the date/time of folders from command-line, without displaying any user interface. The result of the folder date/time update will be saved into the specified log file.
For example, the following command will update the date/time of folders according to the current settings (saved in the .cfg file), and the result will be saved to c:\temp\log.csv:
FolderTimeUpdate.exe /scomma c:\temp\log.csv

You can use the /cfg command-line parameter to load another config file instead of the default one:
FolderTimeUpdate.exe /cfg c:\temp\1.cfg /scomma c:\temp\log.csv

You can also override the settings saved in the .cfg file by specifying the same variable name in the command-line... For example: Inside the .cfg file, the base folder is stored as 'BaseFolder=folder', so you can override this value by specifying the /BaseFolder in command-line.
In the following example, the base folder is set to c:\myfolder and the sunfolders depth is set to 3:
FolderTimeUpdate.exe /BaseFolder "c:\myfolder" /SubfoldersDepth 3 /stab c:\temp\log.txt

In the following example, FolderTimeUpdate is executed in simulation mode, so the result is saved to a file, but without actually changing the date/time of the folders:
FolderTimeUpdate.exe /Simulation 1 /stab c:\temp\log.txt

/cfg <Config File> Start FolderTimeUpdate with the specified config file.
/stext <Filename> Update the date/time of folders and save the log to a simple text file.
/stab <Filename> Update the date/time of folders and save the log to a tab-delimited text file.
/scomma <Filename> Update the date/time of folders and save the log to a comma-delimited text file (csv).
/stabular <Filename> Update the date/time of folders and save the log to a tabular text file.
/shtml <Filename> Update the date/time of folders and save the log to HTML file (Horizontal).
/sverhtml <Filename> Update the date/time of folders and save the log to HTML file (Vertical).
/sxml <Filename> Update the date/time of folders and save the log to XML file.

Translating FolderTimeUpdate to other languages

In order to translate FolderTimeUpdate to other language, follow the instructions below:
  1. Run FolderTimeUpdate with /savelangfile parameter:

    A file named FolderTimeUpdate_lng.ini will be created in the folder of FolderTimeUpdate utility.
  2. Open the created language file in Notepad or in any other text editor.
  3. Translate all string entries to the desired language. Optionally, you can also add your name and/or a link to your Web site. (TranslatorName and TranslatorURL values) If you add this information, it'll be used in the 'About' window.
  4. After you finish the translation, Run FolderTimeUpdate, and all translated strings will be loaded from the language file.
    If you want to run FolderTimeUpdate without the translation, simply rename the language file, or move it to another folder.
