Hi @Zaheer
Welcome to the Box Community!
Sorry to hear about the issue of missing files. To investigate further, could you please provide the following details?
- Is this happening only with files saved from Adobe InDesign?
- Which application are you using for syncing—Box Sync, Box Drive, or Box Web?
- When did the issue start?
- Has it worked correctly before?
- Have you tried connecting to a different network?
- Is the issue affecting all file types?
- Are there any error messages? If so, can you attach a screenshot?
Looking forward to your response. 
I please see responses below
- I see it occured with some other files as well
- Box Drive on Macbook
- It happens some time ago but i thought i was imagining. Then it happened again in front of my eyes and then I realised this is an issue
- I hope so. Like I say. I cannot tell if any other files went missing or vanished as we do save a lot of stuff here
- Yes I worked between 3 networks
- I think it is not isolated to one file type
- No error messages
I also notice sometimes, that if I am uploading a file eg. joesoap.jpeg . it will show that its uploading another file like mary.jpeg in the transfer log. Not sure if that is something to be alarmed about. That does happen often.
