We have an application that works well on all Windows up to W98.

We have a client that tried our application on his window xp and he got the message "Too many files open". This is normaly solved by updating or adding a line in Config.sys (FILES=99).

In Windows 98, if Config.sys does not exist, we just have to create it.
Is it the same in Windows XP or do we have to search for a specialy named file??

Do we have to expect any other "bad surprise" with Windows XP?

Thanks in advance.
