commit 2268b3d64512f93fdeb0a8c5e1591f9e85db879e Author: Hermès Bélusca-Maïto hermes.belusca-maito@reactos.org AuthorDate: Fri Jun 30 22:28:06 2017 +0000 Commit: Hermès Bélusca-Maïto hermes.belusca-maito@reactos.org CommitDate: Sat Oct 27 03:17:29 2018 +0200
[USETUP] Move Setup[Delete|Copy|Move]File() from usetup code into the setuplib's filesup.c .
Remove the commented-out IsValidPath() in that file, and remove as well the temporary prototypes in regutil.c .
