Script to rename image files based on EXIF tags
Description
This script can be used to bulk rename image files based on the date they were taken according to the EXIF tags of the files. The interesting aspect is that you can add or subtract an offset in seconds, minutes or hours, which is extremely useful when you travel across different time zones and forget to adjust your camera’s clock accordingly. Exactly that happened to me one holiday, so I went and created this script.
Everything is controlled through a nice user interface (a simple form). The script comes with a sample set of settings and filters which it writes into an XML file in its directory. You can change the contents of this XML file to match your needs, so you don’t have to scan your files every time you use the script.
N.B.:
- If you click somewhere during a scan or rename run, the progress bar freezes, but the script keeps running in the background. This is some nasty behaviour of Windows Forms when used within PowerShell – PowerShell is not aimed for graphical user interfaces…
- On my Surface tablet running Windows 10, the dialogs are not displayed properly when running the script from the 64bit PowerShell ISE. If run from the command line it works fine.
+++ Update 13 June 2022 +++
The script has been updated, the original version contained a bug regarding the filtering for file types.
Script source code
<#
.SYNOPSIS
Parse folder for JPG / any files, read EXIF date/time and create filenames YYYY-MM-DD_hh-mm-ss.jpg.
Fallback if no EXIF data: use last change time stamp. (c) 2020 Dirk Klassen.
.DESCRIPTION
This script renames JPEG and other files according to the timestamp taken from the EXIF data.
It uses the EXIF tag 0x9003 DateTimeOriginal for renaming, other tags are read and logged.
If no EXIF data is found, the last modification time stamp is taken.
The file name pattern used is YYYY-MM-DD_hh-mm-ss.jpg, with seconds added to the timestamp until
the resulting name is unique.
It displays a dialog where you can select a folder which contains the images. After that,
you can scan the folder for existing EXIF data to be used for the make and model selection.
After selecting filters for make, model and file name prefix, and setting a time offset to
be added to or subtracted from the original time stamp, you can start the renaming of the
matching images. Duplicate files names are prevented by continuously single seconds to the
time stamp until the resulting name is unique.
Default settings are stored in an XML file, by default settings.xml, in the script folder.
A sample file looks like this:
<Objs Version="1.1.0.1" xmlns="http://schemas.microsoft.com/powershell/2004/04">
<Obj RefId="0">
<TN RefId="0">
<T>System.Management.Automation.PSCustomObject</T>
<T>System.Object</T>
</TN>
<MS>
<S N="FolderPath">\\NAS\share\User\Eigene Dateien\Eigene Bilder</S>
<S N="Makes">*,FUJIFILM,HUAWEI,Sony</S>
<S N="Models">*,ANE-LX1,U9200,D6603,FinePix F500EXR</S>
<S N="FilePatterns">*,_threema*,CIMG*,DSC*,DSCF*,IMG*</S>
</MS>
</Obj>
</Objs>
Please note that all settings except FolderPath are comma seperated lists and require at least
a single * as value, and the file patterns require a trailing *. If loading of the file fails,
a sample file is automatically created.
.INPUTS
No input objects expected from pipeline.
.OUTPUTS

.NOTES
Bugs, Ideas (in descending order of priority):
- Save Path, Makes and/or Models to file or Windows Registry for future use
> Decision: Use file instead of registry for easier copying / editing.
Idea: XML? Will work only for an object holding all settings. Use Export-/Import-CliXml to save / load the Object
+ First step: Use file as input for defaults only
> Second step: use file also for saving settings offering various options:
> Option 1: Overwrite settings
> Option 2: Add current settings to existing
+ Rename mp4 videos as well (production date can be derived from file properties)
+ Integrate progress dialogue in main dialogue
> Dismussed, PS event model too complicated.
> Free up space by moving how-to section into seperate dialogue
> Move contents of progress dialogue to freed space
> Change file name info to "old name > new name"
> When starting scanning or renaming, disable all other controls
> Add stop button to stop scanning or renaming action and enable all other controls again
+ BUG: Leading Underscore is now also detected as pattern
+ Split status info in two parts: Numbers above progress bar, file name below
+ BUG: Invalid EXIF tags need to be set to "", e.g. time stamps in the Paris pictures
> Store tags as found and use try...catch when processing the tags
> Fallback for invalid tags can be defined during processing
+ Add GPS tags to list of retrieved EXIF data
> Dismissed, values are split across four tags and hard to interpret
> First, for logging
> Second, for filtering
+ Add direct link to log file, or button for opening it
> Makes no sense, as the dialog is displayed as the topmost window
+ Add radio button to select which of the three EXIF timestamps to use
> Dismissed, will be too seldomly used
+ Add name of current file to scan / rename progress dialogs
+ Prevent resizing of dialogs
+ Add "break" handler to enable interrupting of scan and rename actions
> Idea: Event handler for cancel button sets global variable, which is checked in for-each loop
> Does not work, because of the thread handling of forms and button event handlers. The Click event interrupts the script flow
and does not return to the script after the handler code was executed
> The CancelButton property of the form object is of no use, it just assigns a button
+ Add icons to main, scan and rename dialogs
> No longer necessary, because the standard icon is gone together with controls in the the upper right corner
> A background image might make sense - at some time in the future. Maybe.
+ Make the user interface a bit more intuitive and user friendly by better grouping / aligning of the elements
+ Include also video files (.mov, .avi, .mpg, .mp4) for renaming (only based on file timestamp as there are no meta data in video files)
> Idea: Instead of statically adding numerous possible file extensions, use the scan feature to add only the existing ones,
or just add a radio button "[x] JPG only [ ] All files". A radio button would be easier, because then the value can immediately
be used as input for the file filter (JPG only > .jpg, Allfiles > .*)
> Now implemented with radio button
+ Export image data to file (.csv in addition to log file)
> No, because CSV data is already in the log file and the required section just needs to be copied out
+ Change buttons to "Quit" and "Rename" to enable multiple renaming operations after scanning
> Done
+ Use "DateTimeOriginal" instead of "DateTime" to ensure correct name (not last change)
> Fixed
> Additionally added DateTimeDigitized to list of EXIF tags
+ Improve log file with some stats (total, renamed, name kept, timestamp increased, ...)
> Implemented
+ Parse files in directory to set available Maker, Model and prefix values for filtering
(ScanOnly() function needed, Main() would need too many alterations)
> Implemented for Make, Model and Pattern
> Lines for optical seperation implemented
+ Add Minutes and Seconds to time stamp offset for fine tuning
> Done
+ Use better dialog to select folder
> Not possible using standard file dialogs
+ Enter offset to be added to hour of timestamp for file name creation
> Implemented
+ Write log file
> Done
Interesting EXIF tags:
0x0000 GPSLatitude ascii string Latitude deg/min/sec
0x0001 GPSLatitudeRef ascii string Latitude N/S
0x0002 GPSLongitude ascii string Longitude deg/min/sec
0x0003 GPSLongitudeRef ascii string Longitude E/W
0x010f Make ascii string Shows manufacturer of digicam
0x0110 Model ascii string Shows model number of digicam
0x0132 DateTime ascii string 20 Date/Time of image was last modified. Data format is "YYYY:MM:DD HH:MM:SS"+0x00, total 20bytes. In usual, it has the same value of DateTimeOriginal(0x9003)
0x9003 DateTimeOriginal ascii string 20 Date/Time of original image taken. This value should not be modified by user program.
0x9004 DateTimeDigitized ascii string 20 Date/Time of image digitized. Usually, it contains the same value of DateTimeOriginal(0x9003).
