i would check with the Insync Tool (weapon?) documentation and see if there is any logging, edit session recovery datasets?

If not, you have just learned an important lesson:
always create a back-up before 'EDITing' a file or turn-on any available recovery processing.

I'm not a Insync tool user, but if you "cancel" the edit session and "come out" ...won't it save you?

Hello,

Sorry, but that is nonsense. . .

Every file that might ever be of any value should have regular backups. In fact there have been several managers/directors/vp's/etc that have been fired for failing to maintain adequate backups.

This is not an Insync issue, but rather a management issue. "Anyone" with write access can corrupt or destroy updatable files. It is completly irresponsible for there to be no backups.

Have you checked with your site support group to see if they have backups that they maintain? If not, there's no way to recover deleted data once your session is ended (and possibly not after the enter key is hit -- I don't know how this Insync tool works). Before editing any file you need to verify the backup exists and is current and valid -- because there's always a chance it will be needed when you directly edit the file.

Having said that I wonder if this was about a "production file" . . . icon_confused.gif

If it's a production file, the situation is even worse ... lack of backup of production files is a sign of a site with serious problems.
