Backup recovery
We recommend that you regularly save manual backups with different file names via "File" → "Save as", so that you can revert to the error-free state of the model at any time.
In addition, the program automatically creates backups. These backups are saved as files with a filename ending in a dollar sign ($) in the same directory as the model file. If necessary, you can restore this backup in various ways:
Backup recovery in programs with a single-file system
If the program uses a single file to store the model’s basic information, you will find a single file with a file extension ending in a dollar sign ($). In this case, you can manually replace this dollar sign with the full file extension of the relevant program to try to recover the information.
Example
- We want to recover a CYPE Architecture project. This program saves the project to a .str file, but a backup copy with the extension .st$ has also been generated in the same folder.
- 2. To restore the project, simply change the extension from .st$ to .str. You may also need to rename the file if its name matches that of the original file, provided it is in the same folder.
- 3. Once renamed, the program can open the new .str file from the "File" menu.
Backup recovery in programs with multiple file systems
If the program uses several files to store the model’s baseline information, you will find various files with extensions ending in the dollar sign ($). In this case, you can manually replace this dollar sign with the full extension. This must be done for all files with these characteristics.
Example
- We want to recover a CYPECAD project. This program saves the basic information on the structure of floors and columns in a .c3e file, and has generated a backup copy with the extension .c3$ in the same folder. In addition, the floor plan information is stored in the DAT folder within the same directory, with PLN files corresponding to the information for each floor plan, and PL$ backup files for each of the floor plans.
- To recover the project, copy the .c3$ file to a new folder and change its file extension to .c3e. You must also create a DAT folder and copy the PL$ files into it. You must then change the extension of each of these PL$ files to PLN.
- Once this has been done, the program can locate the new .c3e file in the new folder and open the project with the recovered information.
If there are other elements, such as walls or stairs, you can follow the same process:
- Extract the files containing information on these elements (identified by a $ symbol in their file extension).
- Paste them into the new directory whilst maintaining the same file and folder structure.
- Change their file extension to match that of the original file.
If the error is in a particular floor or element, you can try deleting one of these files (for example, a PLN file for a floor) to see if you can open the project with partial data and recover some of the remaining information.
Backup recovery in Arquimedes
Arquimedes uses a file with the .dbz extension to store the backup. This file is saved alongside the files with the extensions .dbd, .dat and .idx, which make up the contents of the project. To restore the .dbz backup file, you must rename the file extension to .zip and unzip it using a file extraction program. Inside, you will find various sets of files:
- The .i00, .i01, .i02, etc. files correspond to backup copies of the .idx file at different points in time. One of these files can be extracted into a new folder and renamed with the .idx extension.
- The .d00, .d01, .d02, etc. files correspond to backup copies of the .dat file at different points in time. One of these files can be extracted into the same new folder and renamed with the .dat extension.
The original .dbd file must be copied to the new folder so that it is grouped with the new .idx and .dat files obtained through this process.
Once this has been done, Arquimedes can locate the .dbd file in this new folder via the "File" menu and open the project with the recovered data.
