Easy2Sync for Files / Outlook - What is the difference?
You might say the programs are "sister products". Easy2Sync for Files synchronizes any kinds of files (but PST files only complete, which may have disadvantages). Easy2Sync for Outlook however synchronizes Outlook (e.g., PST files) without problems, but it won't work on normal files.
If you want to synchronize both files and e-mails, you'll need both products. You can purchase them in a bundle and get a discount.
