Update. At this point the script works, it's in the right direction thanks to the help of Mark. There are two faults within the script;
- How can I select a folder where to save the files that the script generates at present it is all saved to my desktop ?
- How can I restore all of the files from the last saved workspace, there is no option with the script starting in a clean Ps document to load workspaces from an hour ago, a day ago etc a text file is generated, and all the documents are saved in PSD format, if a week later I want to load it up there is no 'list' that I can call upon within Ps.
I may have a folder
WorkSpace Ps Saver Documents
- [date]
-[date]
-[date]
etc
Hum… you moved the goal posts a bit… The original scripts saved and restored a *single* session…
You now want multi-sessions… I have made some additions to the scripts and hope that they now do what you want…?
In short this is what script closePSSession does… The script now dumps the dated sessions in sub-folders of a main folder 'PS Sessions' on your desktop… Every time this script is run you will create a sub-folder that will contain any unsaved files along with a text log files that were open in this session… If all files had been previously saved then it will only hold the text log…
The script openPSSession should give you a dialog box where you can pick your session from a list made from the sub-folders… The script will read the contained log and reopen all the files in that session list…

Sorry not had the time to comment this up…

Oh and a pretty picture just to show it works all dandy here… no more nightmares…
