how to delete some folders using custom code
hi,
i want to delete some folders in the $USER_INSTALL_DIR$ using custom code in the install task or post install task .
Can anyone provide some suggestion and some sample code for deleting the folders in the $USER_INSTALL_DIR$ say FIRST FOLDER ,SECOND FOLDER in the install task or in the post install task by executing custom code to achieve this.

I'm not sure why you would need custom code in order to delete folders, you've got built-in actions for that.

hi,
i would like to know where i will be able to find the delete file\folder action in the post install task.
And say i want to write custom code for achieving this,isnt it possible to delete a folder in the post install task using custom code action
AND if possible it would be a pleasure to get sample code for doing this.

If the delete file/folder is not available in the post-install task, then why can't you use in the install task (see your initial question). What is your IA version?

A Google search will find an example for deleting a directory.
Here's one result...

James, why would you like to complexify your tasks whenever there are easier workarounds. Ok, so the Delete Files / Folders actions are not available in Post-Install task, but Execute Commands are too! So instead of writing custom code, what prevents you from executing commands like:
CMD /C DEL /F /Q "$TEMP_DIR$ (for Windows) or
sh -c "rm -rf $TEMP_DIR$" for Unices.
Ok, I don't deny, writing custom code would mean that you always execute the same code on any of your platforms, but compare these one-liners with the task of writing, testing and integrating the custom code.
CMD /C DEL /F /Q "$TEMP_DIR$ (for Windows) or
sh -c "rm -rf $TEMP_DIR$" for Unices.

Quoting from the manual:
"Temp Directory $TEMP_DIR$ This variable represents the temp directory on the target machine. When running the pure Java installer on Windows, $TEMP_DIR$ will resolve the user's home directory."
It's usually something like C:\Documents and Settings\UserName\Local Settings\Temp
But please bear in mind the fact that what I gave you was an example (and a stripped one (i.e. I've remove the extra folder that was in the temp folder) that I'm not sure it'll work as is, and that because usually there are other applications using the temp folder, so attempting to directly delete this folder will fail, as certainly there will be other files locked in that folder.

I am extracting a tomcat.zip during the installation into the $USER_INSTALL_DIR$.
during the Uninstallation , the tomcat folder is not deleted, bcoz it has new log files created.... how to delete this..
There is NO option for FORCED delete(Recursively delete) for extracting files.

Create the directory first, then extract the zip. Then you can have the "Recursiveley delete all contents of this folder during uninstall" checkbox checked.

Have you tried the Execute Script/Batch File action? You can write the operating system native script (Unix shell and Windows .bat) in that action to do pretty much everything. Also you can use the IA variables in the script that give you more control.
