Long filenames are truncated to approximately 63 bytes in ACR 8.3/8.4's Save Image... panel. The name truncation happens to the file saved on disk and is visible in the Example Filename area.

It doesn't matter what file format is selected.

This didn't happen in older versions of ACR, according to the user initially reporting the issue.

Examples of truncation are:


Saving as JPG becomes:


which is 62 characters but the next character might need a double-byte to represent the vowel points so that would be too long at 64 bytes.

And if things are "cleaned up" regarding the comma and Ä then:




which is 63 characters.

Here is a screenshot showing the truncation of the cleaned-up name:

The path the files are saved in doesn't seem to matter, where it can be long or short or under the users folder or off the root of the C: drive. This is happening on Windows 7, at least, and at least in ACR 8.3 and ACR 8.4 RC.

For references, here is the original message posted in the Adobe forums, bringing this issue to light:
