Role of preview while converting file from CDS to Gypsy

This rather strange problem came up today when a MB member wanted a file converted from cut file to gypsy.  It threw an error in the gypsy file even though it opened up fine in CDS.
So I took a look at the file. And  tried finding the problem by elimination . And at last found of all the silly things in the world  the problem lay in the preview option.....
When in the CDS cut file you turn  the preview off in all the pages then in the converted gypsy file you get an error!!!!!!!!!!!!!!!!!!!. A quick way to check if a cut file has a preview or not is when you open the cut file in CDS if there is thumbnail then no problem.

This saves you time if a file has lots of pages then going to each page and right clicking and checking if the preview is ticked or not. Since all you need is atleast one page to have the preview turned on you can open CDS and from the CDS file menu press open and see if the fie you want to convert has preview or not. Else just turn atleast one page on and then save the cut file.

Here I always like to close the file and reopen the file before converting to gypsy. It is not necessary you do that. But it is a safe procedure as in  gypsy and sometimes rarely in cds you commit the file by closing. Well better safe than sorry lol. Again I stress I prefer doing it this way.
Isn't that the silliest glitch!! Well anyway there it is.
Also while on the subject a word of advice - when you upload the file always check the file details in G sync window. Sometimes even though the file while loading in G sync will say error loading you may find the file in the window. This one appears. And check the file info next to it. The file had 0 bytes. When you see something like this my advice is try deleting the file from G sync itself instead of opening the G and then the G throwing a fit and you having to reset. For files with error most of the times cannot be deleted from inside the G.   I would recommend deleting the file from G sync itself. Just right click in the G sync window and delete ( in windows).
I did make a video
Here I want to thank Beth & Sassy  for if not for them this video would not be on  today. Yesterday something happened that really turned me off videoing but these two stood by me and encouraged me. I am lucky to have friends like Beth, Sassy and Mya in the MB.
I also want to thank the MB member who brought this problem to me (for her privacy I will not mention her name).
So here is the video
