OneFolderApp
Modified dates are incorrect.
Describe the bug "Modified date" for images are incorrect on Linux.
To Reproduce Steps to reproduce the behavior:
- Look at the properties of any image in OneFolder.
- Compare the modified dates with the image meta data in another program.
Expected behavior If the system says the file was last modified "8/12/25", it should display "8/12/25". Instead, it shows the date it was last changed by OneFolder, I'm assuming.
I added a tag to the image and the modified date updated in OneFolder, as well (but not on the system).
Screenshots
In KDE Gwenview
In OneFolder
OneFolder version
- e.g. v1.1.1
Desktop OS 6.16.3-2-cachyos
Additional context Add any other context about the problem here.
Hello @andrensegura
Would you mind to double-check that the modified value is not an OS-specific value?
What I mean is that file systems keep their own "created" and "modified" dates that are not part of the image metadata. We call it the system date, and the one in OneFolder is the metadata date that is stored inside of the image itself.

It looks like the file system data and the EXIF data match.
What is the specific type of data that I need to modify to match the system data? I can recursively update the fields if I know what OneFolder reads.
Thank you for looking into this!

@bibbleskit we indeed have a problem, thanks for reporting!
Sadly, I am very low on development time for a couple of months, so it will take some time for me to resolve this problem, but I will fix it one day for sure !
In case you are low in patience, you can also try the other forks:
- Here is the original project: https://github.com/allusion-app/Allusion
- Here is a fork of the original project that is currently maintained. I recommend using this one: https://github.com/RafaUC/Allusion
Or if you want, you can always submit a PR, and I can review it
@Antoine-lb I understand the lack of development time. Take all the time you need! Thank you for your work on this project, in general.
I'm back with more information. It looks like all the data is not actually being written as EXIF data. It appears to be XMP.
Here is a screenshot from within OneFolder:
This same image with the data extracted using python Pillow:
import PIL.Image
import PIL.ExifTags
image_path = "/path/to/picrew-concept.jpg"
img = PIL.Image.open(image_path)
exif = {
PIL.ExifTags.TAGS[k]: v
for k, v in img._getexif().items()
if k in PIL.ExifTags.TAGS
}
print(exif)
Output:
projectfolder #:> python get_image_metadata.py
{'ResolutionUnit': 2, 'ImageDescription': 'test description', 'YCbCrPositioning': 1, 'XResolution': 72.0, 'YResolution': 72.0}
The image metadata in Gwenview (KDE image browser):
The tags are kept in the XMP fields "Hierarchical Subject" and "Subject" (and the IPTC "keywords").
And I'm not sure where OneFolder is getting the modify date, since it doesn't match up with any of the metadata.
projectfolder #:> stat picrew-concept.jpg | grep -i modi; exiftool picrew-concept.jpg | grep -i modi

I don't know much about these meta data formats, so I don't want to speculate and say something that might not be helpful, haha. But I do hope that this is somewhat helpful in debugging. I would love to assist if I have the time because I loved Allusion, and OneFolder is absolutely a great step up in the right direction (truly portable via filemetadata is great.
Note, most of these files I am using are ported over from the original Allusion, so they did have metadata on them already. However, I have tried this with a completely new folder with new images untouched by the original Allusion. The issues were the same. I plan on doing more testing to see if it's something on my end.
(I didn't mean to keep looking into this. ADHD is a bitch lol)
I cleared everything out of OneFolder, created a new directory in a completely unrelated path and copied some existing images into it.
Here are the stat and exiftool outputs for the dates.
Here is OneFolder:
It looks like the time I highlighted in pink matches the Birth time in stat's output.
If that's the case, then there isn't a way to correct the time in OneFolder by altering file metadata. As far as i know, Birth time is set by the filesystem for the inode of that file at creation and can't be altered.
Modified (highlighted green) appears to be based on the inode change time, instead of stat's "Modify" time, or exiftool's "File Modification Date/Time" attribute.
