I am using CPANEL and there I edited and created my website directly.
I had php file with about 300 lines and somehow I changed encoding to something other than utf-8. When I changed it and saved it saved only first 10-20 lines of my file. I cannot redo (ctrl+z) to bring my code back.
So my question is how to get lost file back? I haven't closed it yet so session is still valid. Please fast help. I know I will get downvote but I am in despair....
You may be lucky depending on backups...
If you go into the Files section and click Backups, then select the most recent backup where you know your file still existed in the correct state (before you made the encoding change).
If you then save the file and unzip it, hopefully your file will be there and you will be able to re-upload it. Good luck!
In future, definitely develop offline and use source control then upload copies of your file to avoid this.

I have a website that has the old "list files" style of doing things, and I want to perform a hash on a file there before downloading it to the user's local system. I know how to hash a local file, but it seems there's not a lot of info as to whether or not I can do this without downloading the online file. My logic is, if the user already has the same file, why waste time downloading it? So, is it possible to do this?
After further contemplation I decided that the date modified comparison is actually the behavior that I want. If a client were to modify a file on accident, there is now an option to correct it. If they modify it on purpose, I certainly don't want to wipe out their work.
I have a text file. Now I have changed its file type from .txt to .abc. My VB.NET program loads the text into textboxes from that file. After changing the file type, however, other apps like NotePad and Word are able to open and read my .abc file.
Is there any way that only my application will be able to open/read from the file and no other app would be able to do so? What I mean is, suppose I have a PhotoShop document .psd file, no other app, rather that photoshop itself, can open it. How do I make my file unreadable by other apps?
There is no way to prevent an app that you don't develop from opening any file. The extensions are just there for helping us humans, and maybe a bit for the computer to know the default app you select for an extension.
Like you said, a .txt file can be opened by many many apps. You can open a .txt file with Notepad, Firefox, VSCode, and many others.
Same way, a .psd file can be opened by many many apps. You can open that .psd file with Photoshop, but also Notepad, Firefox, and VSCode, and probably the same apps as above.
The difference is which apps can read and understand the file.
In order to make a file not understandable by other apps, you need to make it into a format that cannot recognize, because you planned it "in secret".
Like Visual Vincent said above, you could encrypt the file in a way, or you can have a binary file, that basically only your app knows know to understand.
Since you dont own the app you want the file to be understood by, then you either have to accept that it can be opened by any app that can open files, or you can try to encrypt the file outside the app, or like zipping it with a password, and then decrypting or unzipping when you want to use it.
Firstly, any file can be read unless it is still open by a particular process or service. Even PhotoShop files can be 'read' by NotePad - try it!
So, an attempt at my first answer...
You can try a couple of methods to prevent opening the file, for instance, applying a file lock. As an example, SQL Server .mdf files are locked by the SQL Server service. This happens because the files are maintained in an open state, however; your application would have to remain running to keep these files open. Technically, though, the files can still be copied.
Another way is to set the hidden attribute for the file. This hides the file from the less savvy users, but it will be displayed if the user show's hidden files.
And my second answer: You refer to the format of files by saying only PhotoShop can read or write its own files (not true, but I know what you're saying).
The format of the file must be decided by yourself. You must determine how you are going to store the data that you output from your application. It looks like you have been attempting to write your application data into a text file. Perhaps you should try writing to binary files instead. Binary files, while not encrypted, as suggested by Visual Vincent in the comments to your question, still provide a more tailored approach to storing your data.
Binary files write raw binary data instead of humanised text. For instance, if you write an integer to the file it will appear as a string of four bytes, not your usual 123456789 textual format.
So, you really need to clarify what data you want to write to the file, decide on a set structure to your file (as you also have to be able to read it back in to your application) and then be able to write the information.
We have a process in place built on Excel VBA that uploads a file to FTP Server. On the other side, our client downloads it. Very randomly, they complain that the file they received is blank (the file name is the same though). We then check at our end and see that the file that was uploaded was never blank. So here comes the problem: we're always arguing whether it was our error or theirs.
I figured that there might be a couple of reasons behind it but I have a few questions to ask before coming to conclusions:
If, say, the file was never uploaded (a possibility), what happens when the client runs a download process at their end? Can that download process generate a blank file with the same name as our output file? It sounds impossible to me but since the client is following up on this issue, I have to ask this silly question.
How does the mechanism work - what are the steps that happen on FTP server the moment my process completes uploading the file? I sometimes see that as soon as I upload the file, a 0kb file is created and then a second later (or less) the file with right size appears? Could it be possible that their process is running right before this actual file creation?
Thank you in advance for your help!
So we have a client that creates "training packages" and then uploads them via ftp to their website. They create the training packages in PowerPoint, and then use some program to convert them into html/swf files and package them within a folder. When they upload, they use Filezilla, and just transfer the entire folder over. The folder is uniquely named, uses no spaces or special characters.
These files have uploaded fine for about a year. Recently, they've run into a problem. Whenever they try to upload training package folder, they are immediately presented with the "This file already exists, do you want to overwrite?" message. Except... the folder they're moving is brand new, and the file it's asking to overwrite DOESN'T EXIST. When they choose "Overwrite" the file looks like it transfers, but the file size is wrong, and the training package doesn't work correctly.
This happens with every training package they try to upload. It's not just a badly outputted package. Also, it's always the same file that has the problem--it's the main "player" for the training package, and though it contains different content for every package, it is the same file name (cplayer.swf) every time.
Things they've tried without success:
-Re-uploading the file again by itself, and overwriting
-Deleting the "bad" file and re-uploading the single file - Get the overwrite message again, even though the file DOES NOT EXIST.
-Renaming the file on the server and re-uploading the single file - Get the overwrite message.
-Renaming the single file locally within the package and uploading/renaming it - Won't let us rename because the file already exists.
-Used another FTP client - Same results as above, so not a client specific problem.
-Used a different FTP login - Same results as above, so not a permissions problem.
Other things of note:
-The file is small--it's not a time out problem. Plus, all other files upload fine, and some are a lot larger.
-They've emailed this file to me, and I've uploaded it successfully.
I am completely at my wits end. Does anyone have any ideas where I can at least troubleshoot a little further?
Thanks for the non-help, the downvote, and the general lack of response on what was a pretty serious issue for me.
In case anyone else has a similar problem, here's what was going on:
Virus software (specifically Malware Bytes) was blocking THIS ONE SINGLE FILE. All I had to do was exclude the folder that contained the file.
I've been working with Mercurial (on windows and using TortoiseHg) for some time now, but today I experienced something I just do not understand.
I'm sure, that I've made some modifications to a file (view.xaml). When I manually compare the local file with the one committed to the repository, I can identify the modifications. But when I do a hg status it does not show any modified files...
First thing I checked was, that I had actually saved my work. While doing this, I noticed, that in the windows explorer, it showed the file as modified for just a short time (like 10-20 seconds). Then it changed again and showed as unmodified.
Second thing I checked was the ignore list and view.xaml is not on the ignore list.
Can anyone enlighten me, as to why Mercurial does not show this file as modified?
