Hello and Merry Christmas; I'm encountering an odd problem that probably has an easy fix I'm sure =(. I have three 128GB Sandisk USB Flash Drives ;well one still the main one I mean has 48GB Free; I try to just tried at first to run a Mirror Synchronization, and it fills the second 128GB Sandisk Drive Completely Full to '0MB' Free.
I read, some of the discussion board; and I thought I might need to Compare both locations; but got the same result disk is full.
In a perfect world I would like to have 1 – 128MB Sandisk on my Desktop; and the Second one on my Laptop; then the Third one which would be the Master to be Synced in a bath operation. I know how to do the Task Scheduler for a Batch Operation. But I am at a total loss of what I am doing wrong.
Your software came HIGHLY Recommended; I tried a lesser recommended software DTSynchronizer with the same result.
Please bare with me, I am a disabled and have learning disabilities; but I have 18year of web development experience; as well as I.T. Experience. So you can talk technical to me.
I eagerly await your response. Thank You for Developing such a High Quality Software Product that is available to the Open Source Community of users.
Major problems that require a simple answer!!! Please Help LOVE YOUR SOFTWARE!

Hello and Merry Christmas :)
You might have hardlinked files on your main flash drive. In case you aren't aware of the concept of hardlinks, that means that there are multiple file system entries (=files) pointing to the same memory location. You would have the same content in different folders with different filenames, only occupying drive space once.
If you copy those, most programs don't recognize the hardlinks and see those as independent files, each with their own size and content. So after copying, the one file with two references becomes two independent files; they occupy double the space as before.
There would be two solutions to this:
1. Identify and remove (or ignore in FFS) the hardlinks, in case they're not essential.
2. Use a sync program that is able to detect and maintain hardlinks.
For both tasks I know that there are freeware/open-source tools around, but I can't recommend any. Maybe someone else has something to say here.
The question is: Are you aware of huge files on your flash drive (128GB is quite a lot) that are present multiple times? You could try the following (assuming Windows):
1. Search all files on your main flash drive by entering the asterisk (*) in the search box of the explorer in your main drive's root folder.
2. Sort the resulting list by file size in descending order
3. Look through the first few entries which are the biggest files on your drive and see if there could be doublettes (exact same filesize, maybe same filename, filenames hinting for identical content)
4. Report here :)
