6/11/2023 0 Comments Recursive folder backup python![]() But it is very difficult to back up after every one hour or after every minute. But accidentally, your computer hard disk crashes. Consider that you have made an important presentation after spending a lot of time on it. Sometimes we accidentally or mistakenly delete documents. We often create new documents, files and folders in our computers. The author has created a Python program to help Backup Files Automatically. To avoid the drudgery of physically doing so every now and then, it is best to automate the process. To ensure file and folder security, prudence dictates you take a backup. If you just want to loop through all files, the equivalent of find -type f, you can do this: for currentpath, folders, files in os.walk('.Lost or deleted files are a common phenomenon. And any subfolders of that (though we don't have those in the example). You don't have to do anything to recurse into those folders, because as you see, it recurses automatically and just gives you the files in any subfolders. , that it contains two folders namely pics and docs, and that there is one file, namely todo.txt. So in the first line, we see that we are in folder. This shows us: # currentpath folders files Let's show them: for currentpath, folders, files in os.walk('.'): In every loop, it fills the variables folders and files with all folders and files. So it loops three times, because there are three folders: the current one, docs, and pics. The currentpath is the current folder it is looking at. With this code: for currentpath, folders, files in os.walk('.'): ![]() It's quite simple! Let's walk through this tree: docs/ ![]() TL DR: This is the equivalent to find -type f to go over all files in all folders below and including the current one: for currentpath, folders, files in os.walk('.'):Īs already mentioned in other answers, os.walk() is the answer, but it could be explained better. If you didn't know, the with statement for files is a shorthand: with open('filename', 'rb') as f: List_file.write(('The file %s contains:\n' % filename).encode('utf-8')) Print('\t- file %s (full path: %s)' % (filename, file_path)) With open(list_file_path, 'wb') as list_file: Print('list_file_path = ' list_file_path) List_file_path = os.path.join(root, 'my-directory-list.txt') Print('walk_dir (absolute) = ' os.path.abspath(walk_dir))įor root, subdirs, files in os.walk(walk_dir): # immediately convert program arguments to an absolute path. # If your current working directory may change during script execution, it's recommended to BTW "file" is a builtin, so you don't normally use it as variable name.Īnother problem are your loops, which should be like this, for example: import os So that must be filePath = os.path.join(root, file). files: Files in root (not in subdirs) of type other than directoryĪnd please use os.path.join instead of concatenating with a slash! Your problem is filePath = rootdir '/' file - you must concatenate the currently "walked" folder instead of the topmost folder.subdirs: Files in root of type directory.root: Current path which is "walked through".Make sure you understand the three return values of os.walk: for root, subdirs, files in os.walk(rootdir):
