Migrating TCP Files from Tally 9 to Tally.ERP 9 Format
The Tally application folder contains files other than the data files which are referred to as secondary files. From Release 3.0 onwards the file format of all the secondary files have been standardized.
All the TDL files which were compiled for Tally 9 Release 1.x/2.x having the file extension .tcp needs to be converted to the new format. The existing .tcp files can be converted as follows
- Automatic conversion
- Manual Conversion
Automatic Conversion Process (using installer)
When the current version of Tally is installed in the same folder as the older version then the file conversion is done automatically.
When the current version of Tally is installed in the same folder as the older version then all the .tcp files which were included in the tally.ini file are automatically converted to Tally.ERP 9 compatible format.
The original .tcp file is renamed as <filename>.tcp.BAK i.e., the filename of the converted file is same as the original filename and the original .tcp file is retained as a backup file.
When Tally is installed in the same folder where the Old version is installed then the file Tallysav.tsf is automatically converted to the new format. The file Tallysav.tsf is renamed as Tallysav.tsf.BAK.
The dictionary files in new format are provided with the release. When Tally is installed in the same folder where the Old version is installed then the old files present in the directory will be overwritten by the new ones. It is to be noted that the new dictionary files are not compatible with prior versions.
