Edit-tricks are most useful when multiple tables must be changed, then the time needed to develop complex edit-patterns can be applied to each table. For each table, insert an alpha-prefix on each column (making each row-token "|-" to sort as column zero, like prefix "Row124col00"), then sort into a new file, and then de-prefix the column entries.
Pandas (styled as pandas) is a software library written for the Python programming language for data manipulation and analysis. In particular, it offers data structures and operations for manipulating numerical tables and time series .
Reparse Point (L): The file or directory has an associated re-parse point, or is a symbolic link. Offline (O): The file data is physically moved to offline storage (Remote Storage). Sparse (P): The file is a sparse file, i.e., its contents are partially empty and non-contiguous. Temporary (T): The file is used for temporary storage.
A flat-file database is a database stored in a file called a flat file. Records follow a uniform format, and there are no structures for indexing or recognizing relationships between records. The file is simple. A flat file can be a plain text file (e.g. csv, txt or tsv), or a binary file. Relationships can be inferred from the data in the ...
CAB – A cabinet file is a library of compressed files stored as one file. Cabinet files are used to organize installation files that are copied to the user's system. [2] CPT, SEA – Compact Pro ; EGG – Alzip Egg Edition compressed file; EGT – EGT Universal Document also used to create compressed cabinet files, replaces .ecab
Even binary data files can be compressed with this method; file format specifications often dictate repeated bytes in files as padding space. However, newer compression methods such as DEFLATE often use LZ77-based algorithms, a generalization of run-length encoding that can take advantage of runs of strings of characters (such as BWWBWWBWWBWW).

The CSV file format is one type of delimiter-separated file format. [2] Delimiters frequently used include the comma, tab, space, and semicolon. Delimiter-separated files are often given a ".csv" extension even when the field separator is not a comma. Many applications or libraries that consume or produce CSV files have options to specify an ...
