No, "cheryl'stst" is not a valid DOS filename because DOS filenames cannot contain certain special characters, including the apostrophe ('). Additionally, DOS filenames are limited to a maximum of 8 characters for the name and 3 characters for the extension in the standard 8.3 format. Therefore, a filename like "cheryl'stst" would violate these rules.
There are 8 characters which filename can obtain
In an MS-DOS filename, you may have up to 8 characters followed by a filename extension (eg. .txt, .doc, .bmp) with up to 3 characters separated by a period. In the filename, you may not use the following characters: < > . , : ; / | \ * ? + = " [ ] You may not use spaces either, and the only exception to using a period is separating the name with the extension. Foreign chararacters should be avoided due to codepage differences. Examples of valid filenames: snowcone.bmp report.txt stats.xls Examples of invalid filenames: snow cone.bmp one<two.txt statistics.xls
You can recover your file by undelete command: undelete <filename>
Yes it is a valid name..
Del is used to delete a file in command prompt.
Any old OS like MS-DOS. It supports a filename of 8 characters.
To lock a file in DOS, you can use the ATTRIB command to set the file as read-only, which prevents modifications. The command syntax is ATTRIB +R filename, where "filename" is the name of the file you want to lock. Additionally, you can set file permissions using attributes like hidden or system. However, true file locking in DOS is limited, as it doesn't provide robust file locking mechanisms like modern operating systems.
MS-DOS contains the command "attrib" which accepts two parameters. For example for making a certain file hidden use the following sequence: attrib +h filename. To return to the original condition use the sequence: attrib -h filename.
To display the filename of the current workbook in Excel, you can use the formula =CELL("filename"). This function returns the full path of the workbook, including the filename. If you only want the filename without the path, you can combine it with the MID and FIND functions to extract just the name. For example, =MID(CELL("filename"), FIND("[", CELL("filename")) + 1, FIND("]", CELL("filename")) - FIND("[", CELL("filename")) - 1) will give you just the filename.
Set the printer as the default image printing device, in the DOS window type print D:Devicename Filename | echo. & echo Could not print. & echo. & pause
The extension is the part of the filename after the dot that specifies the type of file (.txt for text files, .exe for executable files, .htm for hypertext markup language files, etc.).
In MS-DOS, the maximum length of a file extension is three characters. This limitation is part of the 8.3 filename convention, where file names can be up to eight characters long, followed by a period and a three-character extension. This convention was designed to ensure compatibility with earlier file systems and remains a characteristic of DOS and its derivatives.
