heidisql. When importing multiple tables: SQL error (1813): Tablespace '`01tst`.`00_tbl_00`' exists

Used by
MySQL 5.7 - x6.4
Open Server - the last

The folders with the database and tables were located first in FOLDER 1 . I reconfigured the server so that the folders with the database and tables are located in FOLDER 2 .

1. When the server was working with folders in FOLDER 1 , I exported the "01tst" database with its tables.
2. Switched the server to FOLDER 2 .
3. I import database "01tst" with its tables.

# PROBLEM 1
MISTAKE
When importing multiple tables: SQL Error (1813): Tablespace ' 01tst . 00_tbl_00 'exists.

I read somewhere that the problem can be removed

DROP TABLE 01tst . 00_tbl_00
or
DROP TABLE IF EXISTS 01tst . 00_tbl_00

did not help

FOLDER 2 ("... MySQL-5.7-x64 \ 01tst \") contained the file "00_tbl_00.ibd" and didn’t seem to draw any attention ... Like "db.opt", but not * .frm. ..
I deleted the files "00_tbl_00.ibd" and "db.opt" (presumably).

PROBLEM 1. SOLUTION 1 (PARTIAL)
1. I import a DB.
2. The program creates a database folder with files: * .ibd and db.opt.
3. It produces an error Example "SQL error (1813): Tablespace ' 01tst . 00_tbl_00 ' exists." or something similar.
4. Delete the folder with the imported database files from the directory, which gives an error.
5. Reboot the server.
6. I carry out the import procedure.
All table, all table are imported, but in some tables not all rows. About 10-15% of the rows are not in the imported tables ... Well, okay ... I will suffer ..

PROBLEM 2
Using the solution PROBLEM 1. SOLUTION 1 (PARTIAL) so added three databases. Then the error began to appear again. see .screen

Question.
1. How to get rid of it errors - SQL Error (1813)?
2. How to fix # PROBLEM 2 ?
