X1 can index individual files for content up to 2GB (2048MB).
X1 can be configured to only index files below a certain size. To alter this setting, please follow the steps below:
1. Tools > Options > Files > Select Files to Scan button. (This setting also applies to Attachments found in supported Email clients).
2. At the bottom of the File Indexing Options screen, under Content indexing options, click the drop down menu and
select the desired file size.
Files larger than this setting will only be indexed for attributes (and not content). Attributes include the File Name, Date, Path, etc.
