Re: Are checksums persisted for similar image searches?

Can't we assume that the data hasn't changed if the file size and the file modified timestamp are the same?

Re: Ignore metadata bug

I noticed that after the scan data in the jpeg file (after the SOS and EOI marker) there are some trailing bytes and after those trailing bytes a new image starts (the preview image which is larger than the thumbnail) with a new SOI, SOS and EOI marker and then again some trailing bytes.

Re: Ignore metadata bug

I know, I have no idea why Sony adds those trailing bytes. I have photos (unedited, straight out of the camera) with more then 22000 bytes after the EOI marker. In that case extending the search for the EOI marker to 4096 bytes isn't enough. Is it possible to make that a configurable field (so I can...

Ignore metadata bug

Alldup 4.4.14 Download a file from a Sony A6500 (for example: https://3.img-dpreview.com/files/p/sample_galleries/4109805089/8077051969.jpg). Make a copy of that file in the same directory and add an IPTC keyword to one of the files. Start Alldup and search for "file content" and "ign...

Re: Performance question: compare by file name and file content

the option "ignore exif metadata of jpeg files" opens every file and check for the metadata... In the comparison criteria I also checked the "file name" option. Is it possible to check whether there is another file with the same "file name" before opening the file to c...

Feature request: Save Checksums

If I start a search based on the file content using a checksum it would be a nice addition if at the end the program would save for each file the filename, filesize, last modification timestamp and the checksum to a file. If I later on want to run a compare on the same dataset I could refer to that ...

Re: AllDup 4 - Open Beta Test

suggestion: further speed improvement Comparing by a checksum value is much faster then comparing byte by byte because the program needs to read the files only once. But even reading those files once can take a long time when a lot of files need to be compared. For that i would suggest an option to ...

Re: AllDup 4 - Open Beta Test

Thx for the very nice and useful application ! 1) Concerning the option "Ignore Exif metadata of JPEG files" Which jpeg markers are being ignored if i check this option ? I have files where the image data is the same but the iptc data was changed and alldup didn't detect them as duplicate....
