To completely and permenantly delete an IDS session:
Disclaimer: This was done on a Windows 7 computer. Windows 8 and Windows 10 will be slightly different procedure for showing hidden files, but the rest should be very similar.
MAKE SURE THE SESSION YOU ARE TRYING TO DELETE IS NOT ACTIVE IN IDS AND MAKE SURE IDS IS NOT CURRENTLY OPEN!!!!!!
Step 1: Open IDS, open the saved session that you want to delete and then tell ids to delete the session. Close IDS once it's finished.
Step 2: Open "My Computer"
Step 3: Double click on the C: drive to open it. You might get a warning message stating that making any changes in there can cause damage to your computer. Just click okay to continue.
Step 4: Make sure your computer is showing hidden files. To do this click on organize on the upper left corner of the window. Then click on folder and search options and then view and make sure the bullet is in front of show all files.
Step 5: Select the folder labeled "Program Data"
Step 6: Select the folder labeled "Ford Motor Company"
Step 7: Select Folder labeled "IDS"
Step 8: Select Folder labeled "Sessions"
Step 9: Click on "Date Modified" at the top of the screen to change the sort order to bring the session you ended last to the top of the list. (This is why I had you open and delete the session is step 1.)
Step 10: Select all of the files that have the tail of the vin you are working on. (Hold the control button while left clicking on them to select more than one at a time.)
Step 11: Once you have them all selected right click on one of them and select "Delete". A message will come up asking if you want to move the selected files to the recycle bin. Select yes. Once they are moved to the recycle bin I recommend emptying the recycle bin to make sure they are gone for good.
Step 12: Open IDS and start the procedure to ID the vehicle again.
It should not ask you if you want to go to the previous session for that vin. If it does you did not delete it properly.
