In [HKEY _ Local _ Machine \ Software \ dzh \ superstk \ Market \]

Only three subkeys of B $,SH and SZ are retained (please keep HK for Hong Kong stocks), and several other subkeys such as futures commodities are deleted.

Then delete the folders of $ $,DC, FI, HK, SC, SF, SG and ZC in the great wisdom X:\dzh2\data directory (please keep HK for Hong Kong stocks) and lose several hundred meters.

Start great wisdom again and see if it is much more refreshing.

1. You can delete the daily line, 5-minute line and 1 minute line data of Shenzhen Stock Exchange and financial futures in Tools-Data Management-Data Consolidation. The daily data storage time in Shanghai is shorter, only 2 or 3 years, and the rest are deleted.

2. In View-Options-System Parameters, under the column of data saving, except for the first item, the saving time of other options is shortened appropriately.

3. When downloading data, remove all check marks, manually add Shanghai Stock Exchange Index and Shanghai Stock Exchange A shares, and choose to download the latest 10 daily data.

After completion, it can reduce the space by about 50%.

I summarized it from the internet. I hope it works for you. If useful, please thank them.
