Missing TIFF files with LIGHTROOM

Solved
karounette -  

Hello,

I use LR Classic. Until yesterday, everything worked fine.

That is no longer the case. I will try to be as clear as possible.

First, I copy my original photos (only RAW) from my camera to my PC (e.g., a trip on 09/12).

Normally, when I process my photos, I export them to JPG in a folder I named (e.g., Bassin d’Arcachon ...).

Until yesterday, the TIFFs were saved automatically with my RAW files in my “09/12 trip” folder.

Today I can't find them anymore!

Have I changed my preferences...?

I've tried every which way, this goes beyond my small skills...

Who could help me?

Thank you very much in advance

    Good evening,

    We must save *.JPG as stated at the beginning... and not *.TIF, it’s not the same thing.

    Additionally, TIF files have become undesirable in many attachments...

      Hello,

      TIFF files are undesirable as attachments simply due to their size.

      My software stores attachments in a separate folder and not in the body of the message, which theoretically prevents automatic opening; it also has (modifiable) a list of forbidden and allowed extensions a priori. There is of course a second step since the antivirus component and the security software are supposed to filter these files when you try to open them.

      Nevertheless, the allowed list includes all image extensions and also compressed extensions (which is not so surprising because it is not the compressed extension itself that can be malicious but the files it contains).

      We ignore double extensions (the need to display extensions in the operating system) and renamed extensions.

      TIFF is a container that in principle cannot contain executables but why not code (for example PostScript).

      TIFF files have been reported as malicious about ten years ago not because they themselves are malicious but to exploit a vulnerability in certain software that opens them (Microsoft Office, LibTIFF libraries...).

      Apart from these particular circumstances, they are no more or less potentially malicious than JPG which, due to compression, can embed code.

      Thank you for this precise response. But I’m not skilled enough to understand everything... I used this TIFF file in certain situations to give it to the printer
