I have read https://rclone.org/crypt/#file-name-encryption-modes.
Are the numbers shown (~246, ~143) just for example? (or minimum of maximum filename lengths?)
Is it that what I should really care is actual underlying cloud provider's environment?
What is your rclone version (output from rclone version)
rclone v1.52.3
- os/arch: windows/amd64
- go version: go1.14.7
Which OS you are using and how many bits (eg Windows 7, 64 bit)
Windows 10 (64bits) Build 19041.450
Which cloud storage system are you using? (eg Google Drive)
This can have file names up to 4k I think, so if you are using crypt with google drive you don't have to worry.
However the examples in the docs are for backend which have file name limits of 255 chars which includes most local file systems and most of the other cloud storage providers. The bucket based backends typically have a total path length of 1024 characters.
