This program will search through all sub-folders in a given directory and rename any files or folders that have invalid characters.
I designed this program to assist users with fixing invalid filenames when backing up large directories to Microsoft OneDrive. By recursively searching through each file and folder, the program can check that there are no invalid characters or filenames that would cause an upload error.
This program generates a list of all file and folder names in the current directory (or the directory specified) and ensures that the names comply with Microsoft OneDrive's filename specifications.
The following names are not allowed. If they are encountered the program will rename them by appending "-renamed" to the file/folder name.
.lock, CON, PRN, AUX, NUL, COM0 - COM9, LPT0 - LPT9, _vti_, desktop.ini
The following characters are restricted in Microsoft OneDrive, and so if they are encountered in any file/folder name, the character will either be deleted or replaced. All trailing and leading whitespace is removed, and any trailing periods are also removed.
" * : < > ? / \ |
If any filenames would be empty after renaming, the program changes the name to "unnamedX" where X is an incremental number. This is to ensure that two unnamed files in the same folder aren't both renamed to "unnamed".
