Despite the compressed format, data can take quite a lot of space. Furthermore, if you use different GMT and DST configurations for the same symbol, the generated HST files tend to add up.

A cleanup tab would get added to the symbol operations dialog (... button) that would detail how much tick data the symbol has, the amount of data stored in HST files with various GMT/DST configurations and it would allow deleting any HST file set or all the data for the symbol.

Note: this feature was implemented in v2.2.1.
