Does Delphi treat .exe files differently based on filename length?

I am currently developing an internal tool using Delphi.

If I call the project and therefore the .exe

RecUtil

It runs fine with no intervention. However if I name the project

RecUpdate

It requires user intervention to allow it to run.

This is a command line utility, the only thing that changes between compiles is the filename of the project and by extension of the .exe.

Essentially once I go over the 8.3 limit I get different behaviour on the same .exe.

Does Delphi compile an .exe differently based on the length of the filename?

I am using Delphi 10.4

If I rename the file after compilation everything is fine it works like normal.

Solution

  • The answer to this is entirely to do with the words in the .exe name and not the number of characters.

    I was naming my .exe recipeUpdate.exe which seems to trigger this UAC issue.

    I removed the word update and it works fine.
