The following options are available during conversion setup:

Files concatenation

If multiple files or a folder is selected for conversion, you can use “Combine Files” checkmark to combine files in different formats into single document. You can set the order in which source files are placed in the combined document.

Convert files in subfolders

This option is available under SharePoint 2007 when a folder is selected for conversion. You can recursively convert all subfolders of the selected folder by using this option. The same subfolder structure is created below the destination folder during conversion. Under SharePoint 2010, the folders are always processed recursively. To process files without subfolders, just select the needed files in a document library view before starting conversion. Do not checkmark any subfolders.

Save destination folder option

Once you have selected Destination folder you can use this option to not have to go through the same steps again. It will save your selection and prepopulate Destination folder field upon next conversion session. 

Overwrite existing files in the destination folder

Destination folder you have selected can already contain some of the files you want to convert. This option allows you to skip conversion for such files and process only files which are not presented in the destination folder.

Browse for destination folder

Corporate site can consists of dozens of document libraries with complex URL to them and manual entering of Destination folder can be a headache. So, to not have to remember the whole URL path to the particular library or subfolder within it you can use Browse button to choose Destination folder visually.

IMPORTANT NOTE: Browse button is only available with Microsoft Office SharePoint Server 2007. Windows SharePoint Services 3.0 does not support picker-tree dialog component used to implement browsing. Moreover, some browsers may have issues with the picker tree dialog that may make this dialog non-functional on some software configurations. This does not affect overall Aspose.Words for SharePoint functionality, as it is always possible to enter the destination folder manually. In most cases, this issue can be fixed by installing latest Service Packs for WSS/MOSS or by shifting to the latest version of the browser you are using.

Different options will help to adjust the conversion process.
