Finding / Restoring missing Data in TimeTabler

Missing Data / Files

The problem:
If you get a message like:
TimeTabler cannot open file C:\TT4win\Data\ACT1.TT4
then it is because a key file is missing.

All the TimeTabler data is stored in a folder called ‘Data’ within the folder where you chose to install TimeTabler [by default this is at C:\TT4win ]

First step:
The first step is to close TimeTabler and reopen it.  Do you still get the message ?
If so, then (if you can) close and reboot your computer.  Do you still get the message ?
If so, try the "possible solutions" below.

Possible solutions:
You can go back to an earlier time, when the file was not missing, by one of these methods:

1-- Restore an earlier Backup file:
Do you have a (recent) Backup that you made by using File->TT-Backup ?
Example: on a USB memory-stick, or elsewhere on your hard drive, or on the network.
If you have, then you can use File->TT-Restore to load that data in again.

2-- Locate then Restore an earlier Backup file:
Or ... if you think you have a Backup File but cannot find it, see the article on Locating an earlier Backup file.
Once/if you find the Backup File, then you can use File->TT-Restore to load that data in again.
[We recommend that you always make Backups of key stages …you can’t be too paranoid near computers.]  [You should also make regular Backups in the AutoBackup Library.]

3-- Search for the missing file itself:
You could try searching the whole hard disc / network for this missing file [and all the others with a file extension of .tt4] in case they have somehow been shifted to another location.

4**-- Move the contents of the folder "C:\TT4Win\Backup" over to "C:\TT4Win\Data" ... this takes you back to an earlier point in time when the "Backup" folder was last loaded.

5**-- Look in the folder “C:\TT4Win\RestorePt” … this contains copies of your data from just before each time you have previously restored a Backup.  You can look in “RestorePt” for a relevant file (a file starting “TT_170915…” means it is a copy of your data from 15/9/17, etc).     If you do want to restore a file from the “RestorePt” folder, then the best way is just to copy the file you want onto a USB-pen-drive (say), rename it to the standard name for a Backup file (“TT4Data.Bak”) - and then “File->TT-Restore” it in the usual way.   See also the article in this KnowledgeBase, by searching on 'RestorePt'.

** Important: before trying either of these methods, please check with the Support Centre.
