1. Overview

This small program realizes the file 1 key copy from the source end to the target end, the source end and the target segment are all on 1 computer, but the directory is different

2. Parameter file description

1. Description of settings. txt
a. By configuring settings. txt, fill in the path of source end and target end. If it ends with a backslash, it means filling in a folder, and if it doesn't end with a backslash, it means filling in a file
b. If the folder is automatically generated by date, replace it with {YYYYMMMDD} or {MMDD}, etc.
c. File support * Match any name
d. In no_create_ok_file group, ok identity is not generated, and in create_ok_file group, ok identity is generated
e. If settings. txt is not filled in correctly, running this applet will generate 1 error. log, but will not affect the subsequent copies

Example
D:\ test3\ {YYYYMMDD}\ = E:\ test4\ {YYYYMMDD}\ If you do not fill in the date when executing the program and enter directly, this {YYYYMMDD} will be automatically replaced with the date of the day, and if you fill in the date (such as 20191115), then {YYYYMMDD} will be automatically replaced with 20191115
D:\ test1\ fa* = E:\ test2\, which means copying all the files starting with fa in the D:\ test1 directory to E:\ test2

2. Description of okfile. txt
okfile. txt fills in the ok file on the source side. Some systems will generate an ok file when generating files, indicating that the system files have been generated. okfile. txt is to verify whether these files exist. If they do not exist, an warn. log will be generated when running this applet, but the actual copy will not be affected.

3. Description of procedures

Because business people don't understand python and don't install a development environment, it is convenient for them to operate by packaging python files into an exe. 


pip isntall PyInstaller #  Installation PyInstaller Bag 
pyinstaller -F filetran.py --icon=rocket.ico #  Will .py Documents and .ico Files are placed in 1 Up, in dist Generate under the directory exe Documents

Since my py file needs to read these two configuration files, I also need to put the. exe file and these two configuration files under the same directory, and then I can execute them under any one windows

Step 4 Attach code
filetran.py

Note that whether you use python to execute filetran. py or click filetran. exe, you need to put it together with settings. txt and okfile. txt, otherwise the program will report an error.
