How many files can I have per directory if my filesystem is F2FS? I know Wikipedia says that max number of files (not per directory) depends, but that's another matter.
I want to make a custom command-line file manager (written in Python) to use in Termux on my Android 10 device. I'd like to have all the files actually just be in the same directory on Termux, but in my own filesystem, they'd be represented differently. So, naturally, I'm curious how many files I can stick in the same directory.

I'm providing a .zip with a .R file and a .xlsx file to some people
I need to make a code that can read this .xlsx file in any directory of any pc.
But as the directories vary from computer to computer, I couldn't find a solution.
IMPORTANT: I'm not using Rstudio for read this .R, so i just can use base functions
Using R - How do I search for a file/folder on all drives (hard drives as well as USB drives) This question don't solve my problem..
Take a look at the here package. When you load the library (library("here")) it sets "base" working directory and then you can use the package to construct relative file paths given that location. For example, if inside your .zip file you have an R script (e.g., My Data Analysis.R) that analyzes data that is kept within a folder called data you could read it in using, for example, read.csv(here("data", "my_csv_file.csv")) and it will construct the full appropriate file path no matter what computer it is on. Of course the file structure of the program needs to stay the same across programs.
I wish to combine many installers and make an exe using Iexpress. Total size of installers is 750MB. I tried combine and generated using Iexpress but the created exe file size is only 80MB. And when i double click and attempt to run the exe, its stated that its corrupted cabinet file and cannot be executed. After that i rebuild two exe files by separated installers into two groups and each group file size is around 300++MB. Both exe files are executed successfully. So i suspect that i cannot build all installers into one exe due to its large size. May i ask whether it is correct that iexpress will restrict the exe file size or i am doing something wrong on this?
I think a IExpress package is limited to about the size of a CD-ROM. If you look at the auto-generated DDF file that IExpress generates, one of the directives it gives is:
.Set MaxDiskSize=CDROM
Probably this means ~650MB.
I tried to find a way to change it, but I don’t see how, sorry.
I'm working on some code in IDL that retrieves data files through FTP that are Unix compressed (.Z) files. I know IDL can work with .gz compressed files with the /compress keyword however it doesn't seem capable of playing nicely with the .Z compression.
What are my options for working with these files? The files I am downloading are coming from another institution so I have no control in the compression being used. Downloading and decompressing the files manually before running the code is an absolute last resort as it makes things a lot more difficult as I don't always know which files I need from the FTP site in advance so the code grabs the ones needed based on the parameters in real time.
I'm currently running on Windows 7 but once the code is finished it will be used on a Unix system as well (computer cluster).
You can use SPAWN as you note in your comment (assuming you can find an equivalent of the Unix uncompress command that runs on Windows), or for higher speed you can use an external C function with CALL_EXTERNAL to do the decompression. Just by coincidence, I posted an answer on stackexchange the other day with just such a C function to decompress .Z files here.
In Perforce, I notice that my work-space is linked to a specific directory (location) in my local hard drive. Is it possible to change the location of this mapping for each file? For example if I have two scripts in two completely different directories locally -
C:/File1.pl & D:/File2.pl
And I want to map these 2 scripts under the same folder in perforce. Is this possible?
The root directory must be the same for all files in a single workspace.
However, you can define multiple workspaces, one which resides on your C:\ disk and one which resides on your D:\ disk.
Generally, a single workspace is used for a single project, and generally all files for a single project are located together in a single area of your workstation. I'm having trouble thinking of a scenario in which you'd want to have files be part of a single project, and yet stored in various places scattered around your workstation. Can you explain your scenario further?
There are techniques (the SUBST command, using Windows Junction Points, etc.) which can be used to create aliases for files on a different disk, but given what you've described, using multiple workspaces seems like the clearest approach to me.
I have one folder on my computer and one folder on a remote server, I transferred a large number of files but for some reason I have now 2 more files in my own folder than on the server so I would like to check which ones these are instead of going through them all manually.
I looked for directory comparison and I found the command diff to display differences, but I tried it for my different two folders and it couldn't find the directory on the remote server. This is what I tried:
diff /Volumes/TC1-SIMDATA/Parallel/ModelWSSim/ fraukje#localhost:parallel/ModelWSSim/
Could anyone hint me what I am doing wrong here?
The diff command works only with file system accessible files and folders (i.e. mounted folders generally speaking).
If you can mount the folders, you'll be able to compare them with diff, else you need to invest some time to find a good diff merge tool with FTP or SFTP or whatever access protocol that you need.
