Query: .tkc files in Tester vs Terminal

 
I have imported external tick data for custom symbols in MT5 and created a script that uses the CustomTicksReplace function to amend the spread.

Ive noticed the .tkc files are slightly different in size in the folder Terminal/Bases vs Tester/Bases and have different 'last modified dates'

My question is, when replacing ticks in the terminal via a script, are the .tkc files not affected in the tester? are these two groups of files inherently different or could someone help me understand the differences between custom symbol data in the tester vs the terminal or point me to a resource so I can appropriately edit my data if not doing so already?

Kind Regards
 
If you change tick data in the terminal, I recommend deleting the folder Tester\bases so that the updated data gets into the tester.

Thank you for the info, I'll try this
