ESEDatabaseView is a simple utility that reads and displays the data stored inside Extensible Storage Engine (ESE) database (Also known as 'Jet Blue' or .edb file). It displays a list of all tables available in the opened database file, allows you to choose the desired table to view, and then when you choose a table, it displays all records found in the selected table. ESEDatabaseView also allows you to easily choose one or more records, and then export them into comma-delimited/tab-delimited/html/xml file, or copy the records to the clipboard (Ctrl+C) and then paste them into Excel or other spreadsheet application.

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. esent.dll (The dll file of Extensible Storage Engine) is not required to read the database.

Versions History

  • Version 1.74:
    • Fixed issue: When copying data to the clipboard or exporting to tab-delimited file, every line contained an empty field in the end of the line.
    • Fixed the export to tab-delimited file to work properly when a column value contains CR LF characters.
  • Version 1.73:
    • Added 'Full Screen' mode (View -> Full Screen or F11 key).
  • Version 1.72:
    • Added 'Sort By' toolbar button.
    • Added 'Open Recent File' toolbar button.
  • Version 1.71:
    • Added 'Show Milliseconds In Time' option.
  • Version 1.70:
    • You can now set your own icon to display near every item instead of the default icon, by changing the ItemIcon line in the ESEDatabaseView.cfg file.
    • You can load icon from .ico file, .exe file, or .dll file. for .exe and .dll files, you can specify the icon index (positive number) or the icon ID (negative number)
    • Examples:

Known Limitations

  • Currently, ESEDatabaseView is somewhat a Beta version. It generally reads the ESE databases properly, but in tables with complex data structure, you may experience the following problems:
    • Some fields in some of the records may display incorrect value or display empty string while it actually contains some data.
    • ESEDatabaseView may hang/stop responding when loading a table with large amount of data.

Example for ESE Databases

ESE Databases are used by many Microsoft products. Usually, the file extension of ESE database is .edb, but in some products the file extension is different.
Here's some examples for .edb files used by Microsoft products:
  • contacts.edb - Stores contacts information in Microsoft live products.
  • WLCalendarStore.edb - Stores calendar information in Microsoft Windows Live Mail.
  • Mail.MSMessageStore - Stores messages information in Microsoft Windows Live Mail.
  • WebCacheV24.dat and WebCacheV01.dat - Stores cache, history, and cookies information in Internet Explorer 10.
  • Mailbox Database.edb and Public Folder Database.edb - Stores mail data in Microsoft Exchange Server.
  • Windows.edb - Stores index information (for Windows search) by Windows operating system.
  • DataStore.edb - Stores Windows updates information (Located under C:\windows\SoftwareDistribution\DataStore )
  • spartan.edb - Stores the Favorites of Internet Explorer 10/11. (Stored under %LOCALAPPDATA%\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\AC\MicrosoftEdge\User\Default\DataStore\Data\nouser1\120712-0049)

Start Using ESEDatabaseView

ESEDatabaseView doesn't require any installation process or additional dll files. In order to start using it, simple run the executable file (ESEDatabaseView.exe) and then use the 'Open ESE Database File' option (Ctrl+O) to open the desired .edb file. You can also drag the database file from Explorer window into the window of ESEDatabaseView.

After opening the desired database file, the combo-box located below the toolbar is filled with the list of all tables found in the database. By default, MSysObjects table is selected and displayed in the main window of ESEDatabaseView. MSysObjects is a system table available in all ESE databases which provides the list of all tables and fields stored in the database.
In order to view the content of another table, simply choose the desired table in the combo-box located below the toolbar.

By default, the table is sorted according to the first column, but you can sort by another field, simply by clicking the desired column header. The sorting is made according to the type of the field, so... for example, if the field is an integer value, then ESEDatabaseView will use a numeric comparison in order to sort the column properly.

You can select one or more records (or select all records with Ctrl+A) and then export them into text/csv/tab-delimited/html/xml file, by using the 'Save Selected Items' option. You can also copy the selected records into the clipboard (Ctrl+C) and then paste them (Ctrl+V) into Excel or other spreadsheet application.

Command-Line Options

/table <Database Filename> <Table Name> Specifies the database and table to open. If the <Table Name> is "*" , all tables will be exported, each table in a separated file.
/SaveDirect Save the database table in SaveDirect mode. For using with the other save command-line options ( /scomma, /stab, /sxml, and so on...) When you use the SaveDirect mode, the database records are saved directly to the disk, without loading them into the memory first. It's recommended to use this option if you export a very large table. Be aware that sorting doesn't work when using the SaveDirect mode.
/stext <Filename> Save the database table into a regular text file.
/stab <Filename> Save the database table into a tab-delimited text file.
/scomma <Filename> Save the database table into a comma-delimited text file (csv).
/stabular <Filename> Save the database table into a tabular text file.
/shtml <Filename> Save the database table into HTML file (Horizontal).
/sverhtml <Filename> Save the database table into HTML file (Vertical).
/sxml <Filename> Save the database table into XML file.
/sjson <Filename> Save the database table into JSON file.
/sort <column> This command-line option can be used with other save options for sorting by the desired column. 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 "StatusState" and "CalculatedBuddyIdentifier". You can specify the '~' prefix character (e.g: "~CalculatedBuddyIdentifier") 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.
/Columns <Comma Delimited Columns List> You can use this command with the other save commands (/scomma, /stab, and so on) in order to export only the specified columns, instead of all columns.
You have to specify the field names, delimited by comma, for example:
ESEDatabaseView.exe /table "c:\temp\DataStore.edb" "tbHistory" /scomma c:\temp\history.csv /Columns "ClientId,Title,Description,IdEvent"

ESEDatabaseView.exe /table "c:\temp\contacts.edb" "SimpleContact-v081111-0122-1303" /scomma c:\temp\1.csv
ESEDatabaseView.exe /table "c:\files\contacts.edb" "SimpleContact-v081111-0777-1111" /shtml c:\files\1.html /Sort "CalculatedBuddyIdentifier"
ESEDatabaseView.exe /SaveDirect /table "c:\files\DataStore.edb" "tbHistory" /scomma c:\temp\DataStore_History.csv
ESEDatabaseView.exe /table "c:\files\DataStore.edb" "tbHistory" /scomma c:\temp\DataStore_History.csv /Columns "ClientId,Title,Description,IdEvent"

Example for exporting all tables: (Each table is exported into a separated file)
ESEDatabaseView.exe /table "C:\temp\WebCacheV01.dat" * /scomma "C:\Temp\export\webcache_*.csv"

The table name will replace the '*' character specified in the export filename. For example, if the table name is Container1, then the exported filename will be webcache_Container1.csv

Translating ESEDatabaseView to other languages

In order to translate ESEDatabaseView to other language, follow the instructions below:
  1. Run ESEDatabaseView with /savelangfile parameter:
    ESEDatabaseView.exe /savelangfile
    A file named ESEDatabaseView_lng.ini will be created in the folder of ESEDatabaseView 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 ESEDatabaseView, and all translated strings will be loaded from the language file.
    If you want to run ESEDatabaseView without the translation, simply rename the language file, or move it to another folder.
