Duplicate detection based on file content ?

Duplicate detection based on file content was introduced in March 2020, so if you are running an older M-Files version you should upgrade to get the feature. If you are running a later version already, make sure the feature is not disabled in the vault configuration: How to Disable Duplicate File Detection

Thanks - I muss have missed that one. We are indeed running latest version and from time to time get alerts but I’m pretty sure we still have duplicates slipping in.
Two more questions if I may

Not sure to understand “In some cases, the MD5 value can be different even when the file content of the compared documents is the same. This happens because some files formats store additional metadata in the file which changes the MD5 value.” - would you have an exemple ?

Is there a “hidden” metadata that can surface the hash in the GUI (or API) ?

As far as I know the hash itself is not available via the API, but there are several methods to find duplicate files: FindFileDuplicates, FindFileDuplicatesBasedOnPath, FindFileDuplicatesOfObjVer, FindFilesByChecksumWithNumericalDigests, FindFilesByChecksumWithStringDigests, FindVaultDuplicates, HasFileDuplicates

Thanks

Any insight about the weird (to me)  low and high digest values being used ? Why on earth are you splitting the MD5 checksum into two halves ?
