|TS1607: Helix Collection Can’t Find Recovery File|
When trying to open a collection, a dialog says Helix could not find the recovery file. The collection passes through both utilities with no problems reported.
The collection’s internal flag that tells it to require a recovery file must be reset. We have written a script that can reset this flag. However it is absolutely critical that the collection be checked (and passed) by both utilities before using this tool.
This problem occurs if the computer freezes (or Helix crashes) at the end of a save. When data is saved in Helix, it is transferred from the recovery file to the collection, the collection file is saved, and then the recovery file is reset. If the collection passes both utilities, you can be confident that no data loss or structural damage will result from this situation.
In Helix 6.2.1 and later, scratch and recovery files are stored in the ~/Library/Caches/TemporaryItems/ directory.
