Working with the Flash File System
Restoring Deleted Files
You must specify the index number of a deleted file to identify the file to undelete. The index number
for each file appears in the first column of the
dir
command output. A file cannot be undeleted if a valid
file with the same name already exists. Instead, you must delete the existing file and then undelete the
desired file. A file can be deleted and undeleted up to 15 times.
To restore deleted files on a Flash device, perform this task in privileged mode:
This example shows how to restore a deleted file:
