Not working modtime (flag –ignore-size) on mega

w.v · April 29, 2026, 11:55am

What is the problem you are having with rclone?

Instead of checking modtime rclone checks by size despite flag "--ignore-size" (mega supports modtime read) and says that files wasnt changed and even didnt update modtime

Run the command 'rclone version' and share the full output of the command.

rclone v1.73.4

os/version: unknown
os/kernel: 6.1.118-android14-11-o-g778e4490e346 (aarch64)
os/type: android
os/arch: arm64 (ARMv8 compatible)
go/version: go1.25.9
go/linking: dynamic
go/tags: none

Which cloud storage system are you using? (eg Google Drive)

Mega

The command you were trying to run (eg `rclone copy /tmp remote:tmp`)

touch "$f"
rclone copy -vv --ignore-size -n "$f" M1:

The rclone config contents with secrets removed.

[M1]
type = mega
user = w@live.**
pass = ***

A log from the command with the `-vv` flag

Mega does not support modification times or hashes yet

please post rclone lsl -vv --dump=headers for just that one singie file.

w.v · April 29, 2026, 12:16pm

rclone lsl M1:/1.txt
    61870 2026-04-29 15:00:40.000000000 1.txt
rclone lsl "$f"
    61870 2026-04-29 15:05:09.810499092 1.txt

So the modtime is present.
Also we can see this here in table of remotes
