Settings for the Files Activity
Maximum number of files to upload at a time
The File Upload dialog is where users choose the files they want to upload. Users can select up to ten files to upload at once. This maximum number is set in the MaxUploadFileCount key as follows:
<appSettings>
  <add key="MaxUploadFileCount" value="10" />
</appSettings>
Do not increase the limit to more than 20, because the dialog does not scroll; if you set a larger limit, the Upload and Cancel buttons disappear off the bottom of the dialog.
File types that cannot be uploaded
The Files activity does not allow you upload files with the following extensions: .asp, .aspx, .cs, .dll, .exe, .htc, or .vb. If you upload a zipped file containing files with these extensions, Files will not extract those files either.
To change this list or add restrictions for other file types, do the following:
1 In DPM Explorer, navigate to Site > Servers > ServerName > Applications > ManageFiles > Application Settings.
2 Add a property named InvalidUploadExtensionList, and then specify a list of the file types you want to block, separated by semicolons, in the value field.
3 Click OK.
To work with DPM Explorer, see DPM Explorer.
