Top Forums UNIX for Advanced & Expert Users limit to number of files in a given directory Post 47253 by oombera on Thursday 5th of February 2004 03:14:14 PM

Interestingly enough, I would've thought the only limit was disk space, but then I found one of Perderabo's posts from last summer. I forgot that directories are themselves files and that all files might have a max size.

https://www.unix.com/unix-for-dummies-questions-and-answers/10548-linux-solaris-has-any-limit-folder-size.html?s=

But after reading it, it pretty much looks like the same as what Optimus_P said ... you'll probably run out of usable disk space before you run into any of these other limits on a directory.

Of course, if you keep putting so many files in one directory, you're gonna run into other problems trying to manipulate them (even simple things like just listing all the files).

NAME
Ukopp - copy files to USB stick or other disk or disk-like device SYNOPSIS
ukopp [ -nogui ] [ -job | -run ] jobfile DESCRIPTION
Ukopp is a graphical menu-driven program operating in its own window. Ukopp copies the files and directories specified in the job file to disk or disk-like media (e.g. USB stick). OVERVIEW
Ukopp works incrementally: only files that are not already identical on the target media are copied (new and modified files or files newly added to the backup job). Files/directories to include or exclude can be selected from the file system hierarchy, using a GUI navigator. Specifications are saved in a job file which can be re-edited and/or executed. Ukopp can be run in batch mode using the -nogui option. Ukopp can optionally keep old file versions instead of replacing them with updated versions. The retention time and/or the number of old versions to keep can be specified for each selected file or directory. File owners and permissions are retained even if the copy media has a Microsoft file system. Summary of functionality: - Copy files incrementally with optional file version retention. - Three media verification modes: full, incremental, compare. - Report disk:backup differences in detail or summary form. - Select and restore files from backup media or use drag and drop. OPTIONS
Command line options: [ -job ] jobfile open job file for editing [ -nogui ] -run jobfile execute a job file SEE ALSO
The online user manual is available using the menu Help > contents. This manual explains Ukopp operation in great detail. AUTHORS
