We have EPS files with a custom extension, it seems that Bridge doesnt recognize the file type and just displays a very low res preview. If we change the extension in the finder to EPS it displays correctly. Does anyone have any ideas on how we can get Bridge to display these files correctly?
We have EPS files with a custom extension
An extension usually gets created by the application that saves it and with that extension other apps can open them again in correct format. Changing the extension manual is not the correct route to follow
Bridge only has a limit number of predefined extensions that is able to handle and you can't add a custom one for it.
Since you state after adding the correct extension the open file command works as expected you can use batch rename in Bridge to change the extension for all files in one go.
First create a back up of the originals, then select the files to rename and choose menu tools / batch rename
From this menu select the first field as Current Filename (with second field to only Name)
Use a second row (if not already showing use plus sign to create a new line) and in here choose New Extension. in the text field type the new extension that works. Delete extra lines with the plus sign and check the preview details at the bottom for a correct new filename with showing only 1 extension.
Hit OK and you should be able to use them under the normal file type association criteria in the Bridge preferences.
