How to convert these folders into .CSV file.

[Digvijayapatro]

How can I use the folder files in my code as .CSV format. Because in contains 2000+ files, so merging them is not possible.
df_1_1 = pd.read_csv("/content/drive/MyDrive/Data2/learning_set/acc_Bearing1_1.csv")
df_1_2 = pd.read_csv("/content/drive/MyDrive/Data2/learning_set/acc_Bearing1_2.csv")
df_2_1 = pd.read_csv("/content/drive/MyDrive/Data2/learning_set/acc_Bearing2_1.csv")
df_2_2 = pd.read_csv("/content/drive/MyDrive/Data2/learning_set/acc_Bearing2_1.csv")
df_3_1 = pd.read_csv("/content/drive/MyDrive/Data2/learning_set/acc_Bearing3_1.csv")
df_3_2 = pd.read_csv("/content/drive/MyDrive/Data2/learning_set/acc_Bearing3_2.csv")

Tell me how did you converted these folders into .CSV file.
