The idea is to use this event (or any ZipMaster event) to set the path and
name of the files in the zip archive. I mean in my project the zipped files
have completelly different path than the original disk paths, so i need a
possibility to rename the files or even disable some of them.
I found this event usefull because i have the ExtName parameter. In my case
the option AddDirNames is not important at all because I simply ignore the
FileName parameter and I rename the file.
I've used ZipMaster 1.78
1. My First Solution: I've tried without AddDirnames. This is working
because anyway i set the path, using the information from ExtName. It is
also possible to set nothing to filename and the file is not added at all.
Maybe it's a bug (very usefull in my case).
What I found not very logic : i cannot add files with the same filename,
even if i rename them.
Probably you check the Filenames, why you don't check the renamed files to
see if you have duplicate filenames ?
Ex:
C:\My Files\duplicate.txt ->
MyStorageFolder\duplicate.txt
C:\My Files\Folder\duplicate.txt ->
MyStorageFolder2\duplicate.txt
C:\My Files\Folder\todelete.txt -> (nothing)
-empty allowed
-duplicate is not possible, because of duplicate filename.
2. My Second Solution: with AddDirnames
Ex.
C:\My Files\duplicate.txt ->
MyStorageFolder\duplicate.txt
C:\My Files\Folder\duplicate.txt ->
MyStorageFolder2\duplicate.txt
C:\My Files\Folder\todelete.txt -> (nothing)
- empty not allowed (Bad Zip Options)
-duplicate is possible
-------------
Question: is there any possibilty to solve this problem ? An event to rename
the files and to cancel some.
