FS RM
file_or_directory
Removes the file or empty directory specified by
file_or_directory
. This command fails with an error if
file_or_directory
does not exist, is not empty, refers to the current working directory or one of its
parents.
Note
Removing a file only reclaims space if the file removed is placed last in the file system. Deleted
data that is contiguous with the last deleted file is also reclaimed. Directories are only reclaimed if all
directories in that particular block of memory are deleted and found at the end of the file system. Use
the
ATFS INFO FULL
command to see where in the file system files and directories are placed.
FS INFO
Report on the size of the filesystem, showing bytes in use, available, marked bad and total. The report
ends with a blank line, as with most multi-line AT command output. Example output:
204800 used
695296 free
0 bad
900096 total
FS INFO FULL
Reports every file and directory in the order they are placed in the file system along with the amount
of space they take up individually. Also reports deleted space as well as unused directory slots.
Example output:
128 /flash./
128 /flash/lib./
128 /flash/directory./
1664 [unused dir slot(s)]
2048 /flash/file1.txt.
2048 [deleted space]
2048 /flash/directory/file2.txt

followed by a carriage return when it finishes.
