This was true for old applications and maybe for some older file systems. Modern applications (what means >= Windows 2000 or so) should take the string after the last dot as file extension.papercoffee wrote:You should never use dots inside a file name in a windows environment. Dots are used to separate the file name from the file extension.
(Multiple dots are also taken with pleasure by malicious E-mail senders to hide the "true" extension of an attachment for windows users on a low knowledge level (e.g. Invoice.pdf.exe)).
My UT client running on Windows opens a map with multiple dots in file name fine as well as UnrealEd. But my Linux server refuses loading: Servers can't open net work URLs. I guess that Engine.[dll|so] implements a check algorithm that gets confused by such file names. (A map named "Test.this" is also refused.))
